OMG, Can you believe it? I found the commercial after about 15 minutes!
-feign shock, and faints-
JK JK. I'm not kidding when I said I found the video. This is is.
I do assume the music here is appropriate because I didn't hear the music. :D I was listening to the radio instead. :D
So, I have assumed that you have watched the video, it's short and it won't take up too much of your time, just maybe some of your minutes. :D
So, let me tell you the aim of the commercial again. The aim of the old Dove commercial is to tell all users that the Dove soap contains less alkali then other soap, like, it has a pH value of 7.
So I've just finished reading Sarah's post on this, and it really got me wondering, and I also do totally agree with her. :D
Well, what she said was that since that the pH value is about 7, what is the point of the soap when we can just use water?
Makes good sense right? I know I do. :)
I was thinking....you do know that alkalines are soapy right?
So by making the soap less soapy, the bar won't drop that often!
Okay, I know that's =.="'
Okay, sorry for the no-answer post.

Transition Metal
Hello! Welcome back!
I know you must be very psyched to be reading this again! :) Anyway, this term's subject is still Chemistry, and the topic is Atoms. So now you must wondering what has the Periodic Table got to do with Atoms? Well, atoms have chemical symbols in them, and the Periodic table shows the Chemical symbols (Elements) and the number of protons, electron, and neutrons, which is needed to find out about the atoms. (refer to the previous previous post to read it again!)
Does it answer your question?
But, that is not the main topic for this post! The main topic is called Transition Metals.
#1
Transition Metals are located in groups IB to VIIIB.
As the possess the properties of metals, the transition elements are also known as the Transition metals.
What makes them so special is that they are able to put more than eight electrons in the shell that is one in from the outermost shell. In other words, this is the point in the periodic table where you can place more than 8 electrons in a shell.
Another point is that these metals are really very hard, with super high melting points, and boiling points.
The transition metals are able to put up to 32 electrons in their second to last shell.
Something like gold (Au) has an organization of 2-8-18-32-18-1.
Of course, there are still some rules. No shell can have more than 32 electrons. It's usually 18 or 32 for the maximum number of electrons.
Transition metals can use the two outermost shells/orbitals to bond with other elements.
It's a chemical trait that allows them to bond with many elements in a variety of shapes.
Example: Molybdenum (Mo) with 42 electrons. The configuration is 2-8-18-13-1.
It is therefore unstable. Those two orbitals (13 and 1) can use the electrons to bond with other atoms.
So what are it's uses?
Alloys
Transition metals are commonly used to create alloys, which are combinations of metals and/or non-metallic substances.
Many well-known substances are alloys made of transition metals.
Iron is combined with carbon and a variety of other substances to make steel, and the inclusion of chromium makes it stainless steel.
Copper makes up several well-known alloys: it is mixed with zinc to create brass, combined with tin to form bronze and mixed with nickel to form cupro-nickel, which is often made into coins.
Catalysts
Some transition metals and compounds of transition metals are used as catalysts in chemical reactions to speed up the rate of reaction without adding any reactive properties themselves.
For example, vegetable oils are turned into saturated fats that take longer to melt by way of hydrogenation.
Nickel is used as the catalyst so that hydrogen can effectively join a carbon-carbon double bond.

HYDROGEN BOMB! BOOMZ!
Scary huh? I mean does it sound scary?
Let me scare you with some pictures first! MUSHROOM!
The hydrogen bomb functions by the fusion, or joining together, of the lighter elements into heavier elements.
The end product again weighs less than its components.
Extremely high temperatures are required in order to initiate fusion reactions.
The hydrogen bomb is also known as a thermonuclear bomb.
The first thermonuclear bomb was exploded in 1952 at Enewetak by the United States, the second in 1953 by Russia (then the USSR). Great Britain, France, and China have also exploded thermonuclear bombs.
Structure of the bomb. Easy, but super dangerous.
Process of it.
Like other types of nuclear explosion, the explosion of a hydrogen bomb creates an extremely hot zone near its center.
In this zone, because of the high temperature, nearly all of the matter present is vaporized to form a gas at extremely high pressure.
A sudden overpressure, i.e., a pressure far in excess of atmospheric pressure, propagates away from the center of the explosion as a shock wave, decreasing in strength as it travels.
It is this wave, containing most of the energy released, that is responsible for the major part of the destructive mechanical effects of a nuclear explosion.
The details of shock wave propagation and its effects vary depending on whether the burst is in the air, underwater, or underground.

Orbital theory...Sounds so Chim!
Well, this was supposed to be called the Molecular Orbital Theory, or MO Theory.
The goal of molecular orbital theory is to describe molecules in a similar way to how we describe atoms, that is, in terms of orbitals, orbital diagrams, and electron configurations.
Humph, I wonder how it will be done...
Orbital diagrams are usually drawn to make things easier to understand. :D
O2
O
These 2 pictures are actually diagrams for O2 and O. They are oxygen! :p
Each line in the molecular orbital diagram represents a molecular orbital, which is the volume within which a high percentage of the negative charge generated by the electron is found.
-The molecular orbitals are filled in a way that yields the lowest potential energy for the molecule.
-The maximum number of electrons in each molecular orbital is two.
-Orbitals of equal energy are half filled with parallel spin before they begin to pair up.
It can usually be found in this equation:
Isotopes!
Welcome back to the next series of Atoms! I really hoped you had fun in reading the previous post! Anyway, due to time constrain, I have fast forward the lesson to Isotopes!
So what exactly are Isotopes???? Hmmm...
Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes.
Refer to the previous post to recap on what is Neutron! :)
Hydrogen
The most common isotope of hydrogen has no neutrons at all; there's also a hydrogen isotope called deuterium, with one neutron, and another, tritium, with two neutrons.
You might now wonder how many Isotopes can 1 element have.
Well, sad to say that an atom cannot just have any number of neutrons. There are combinations of neutrons and protons, at which the forces holding nuclei together seem to balance best. Atoms with a few too many neutrons, or not quite enough, can sometimes exist for a while, but they're unstable.
So what is unstable in the above question?
Unstable atoms are radioactive: their nuclei change or decay by spitting out radiation, in the form of particles or electromagnetic waves.
Radioisotopes/ Radioactive Isotopes
That question above ^^^^^ leads me to the next topic, called radioisotopes!
It is well, sad to say that Radioisotopes are really really really (I mean really) dangerous.!!!
Because the like charges of the protons repel each other,there are always forces trying to push the atom nucleus apart. The nucleus is held together by something called the binding energy.
In most cases, elements like to have an equal number of protons and neutrons because this makes them the most stable. Stable atoms have a binding energy that is strong enough to hold the protons and neutrons together.
Even if an atom has an additional neutron or two it may remain stable. However, an additional neutron or two may upset the binding energy and cause the atom to become unstable.
In an unstable atom, the nucleus changes by giving off a neutron to get back to a balanced state. As the unstable nucleus changes, it gives off radiation and is said to be radioactive.
I'm sorry to say that the picture isn't clear, but I can tell you that it is giving out radioactive waves...Reminds me of the Bombing at Nagasaki. 0-0
Other facts
You'll get why I am showing you the Table :)
All elements with atomic numbers greater than 83 are radioisotopes meaning that these elements have unstable nuclei and are radioactive.
Elements with atomic numbers of 83 and less, have isotopes (stable nucleus) and most have at least one radioisotope (unstable nucleus).
As a radioisotope tries to stabilize, it may transform into a new element in a process called transmutation.
Uses of Radioisotopes
Shocking?!?!?! Yes, it can be used in medication you know! -Feign shock-
One major use of radioisotopes is in nuclear medicine. Of the 30 million people who are hospitalized each year in the United States, 1/3 are treated with nuclear medicine.
There are nearly one hundred radioisotopes whose beta and/or gamma radiation is used in diagnosis, therapy, or investigations in nuclear medicine. The most used radioisotopes were discovered before World War II.

Chemistry.....Atoms!
Wasssssssssssssup People! It's officially chemistry for this term! One last term before the EOYs! But anyway, I'm here to tell you more about atoms, and not here to make you depressed by telling you that the next term is the EOYs.
So anyway, let me give you a brief overview of the whole topic on Atoms...I guess. :)
So I'm sure you will ask, what are Atoms?
Before I start on anything official here, please do read up on elements. It will help you greatly in the first part, which is now. :)
All elements are made up of Atoms.
This picture below shows what scientists have found, the shape I mean.
The picture above shows the interior of an atom. Fasinating isn't it?
You might be wondering what are the headings there, and it's quite easy to understand actually.
The nucleus of an atoms consists of Protons, and Neutrons. Protons are POSITIVELY CHARGED, while Neutrons are NEUTRAL.
Electrons are the small little particles orbiting the nucleus. They are NEGATIVELY CHARGRED.
The picture below might actually help you! :)
However, if you have taken a good look at the periodic table, you are able to see that there are over a HUNDRED elements. And each element has a different number of neutrons, protons, and electrons.
Now, how do you know which number is the proton number (atomic number), and which is the mass number (made up of protons, and neutrons)?
So let me tell you again, if you didn't quite understand what I was talking about.
Mass Number
-Usually at the top left hand of the element box (right in this case)
-Made up of Protons, and Neutrons
Atomic Number
-Usually at the bottom left of the element box (right in this case)
-Number of Protons
Facts
You might have noticed that although it is the same element, the mass number is different, but it's not any typo error. There is a scientific explanation behind it. The element here is Carbon. In this case, carbon is in different proportions, and that is why the mass number is different, but it is still carbon in any case.

Digestion - Alimentary Canal
Hey Sup People! How are you doing this afternoon? Hope you are doing gggggggggrrrrrrrreeeeeeeaaaatttt! (GREAT)
Okay, enough of the introduction :) So today's topic is also about Digestion, but we're moving on to another topic, the Alimentary Canal. I know you must be thinking: "Hey we've learnt this before! Why are we learning this again?" Yes I know that question very well, but here, we're going in dept about all the organs, and stuffs.
So let me list out the enzymes the substrates, and the end product.
Carbohydrate
Starch ( Salivary Amylase) Maltose
Maltose (Maltase) Glucose
Protein
Protein (Pepsin) Polypeptides
Polypeptides (Erepsin/Trypsin) Amino Acids
Fats
Fats (Bile) Emulsified Fats
E. Fats (Lipase) 3 Fatty acids + 1 Glycerol
Okay, so now you've seen all the reactions, let's get down to all the organs in the alimentary canal, and their functions. Please get your paper and pens/pencils ready, for the next few paragraphs would be a rollercoaster ride. (0_0 That's exaggerating)
Mouth
Oesophagus
Stomach
Liver, Gall Bladder, Pancreas

Mouth
- Contains teeth that chews food molecules into smaller food substances so that it would have a larger surface area for more enzymes to act on it
- In here, starch is digested by the salivary amylase to form maltose
- The saliva secreted by the salivary glands produces the enzyme, and it also softens, and mixes the food
- The tongue rolls the partially digested food into a bolus before it is being swallowed down.
Oesophagus
- It is also known as the gullet, but at this level, it should be called the oesophagus
- No digestion takes place here
- There are 2 muscle that aids in Peristalsis (The next point) - the longitudinal muslce, and the circular muscle
- Peristalsis - The rhythemic wave-like contraction of muscles that propels and mixes the contents of the alimentary canal forward
Stomach
- The stomach is an elastic, muscular bag with thick elastic walls.
- It secretes a mixture of gastric juice - hydrochloric juice, pepsin, and rennin
- The stomach contracts and relaxes so that the foods are well mixed with the gastric juices
- In here, protein is being digested in polypeptides by the enzyme pepsin
- The end product is a semi-liquid product called chyme, that is being released into the duodenum, the first part fo the small intestine.
- The interesting thing about a stomach is that it is the only organ which has a pH value of 2 (refer to the previous post about pH values)

Digestion - Enzymes
Hey's People, I'm back after a break, if you can see the timing. But anyways, here's the 2nd part of the mighty digestion! (Y) The.....*Drum Roll Please*.....Enzymes! (Y)
Anyway, Enzymes are really simple to understand, but you have to remember a lot of things, but if you write it all out on 1 piece of foolscap paper, I guess you'll remember it better, by a lot, so anyways, good luck!
So Here's the Definition of enzymes.
Enzymes are Proteins. (Please remember that) They are biological catalysts that help speed up the rate of chemical reactions without themselves being broken down at the end of the reaction. (How cool is that?)
Enzymes - Conditions
Yes, there are conditions, like the T&Cs that we humans have. There are 2 main conditions for the best enzymes reactions, and I think you'll find it easy to remember. :)
1. Optimum Temperature
It basically means the temperature at which the enzymes works best in, which is room temperature of about 37 degrees or so (plus minus) and some questions usually states 40 degrees, which is also considered. At this temperature - room temperature - the enzymes reactions with the substrate is at it's peak, but after that temperature, the enzymes would slowly denature, meaning that the reactions would become slowly, and the enzymes would slowly die.
However do please take note that in scientific terms, the enzymes do not die but denature.
2. pH Values
Sorry to say that we have not learnt Chemistry as we would be learning it the next term, but I guess it is just the acidity and the alkaline, and in this case, it is the pH values of the enzymes.
salivary amlase works best in pH7
protease works best in pH2
lipase works best in pH 7~8

Digestion - nutrients
Heys People! I know I'm posting at such a late date, but at least I posted....right? Anyways, here is what I think is the summary of digestion. I've summarised the points I think is required for the exam, as well as adding in several other informations I think it would be fun to know, maybe. But anyways, here it is!
Digestion is basically just the breaking down of large, insoluble, indiffusible food substances into smaller, soluble, and diffusible food substances.
Easy to remember...right? Yeahs.
So anyways, there are 3 types of nutrients in total - carbohydrates, proteins, and fats.
Carbohydrates:
It provides energy for the body cells.
There are 3 types of carbohydrates, mainly the diasaccharides, monosaccharides, and the polysaccharides. I would not go into detail for that as you people have to study!!!
So anyways, there are 2 type of tests for carbohydrates, the Benedicts Test and the Iodine Test.
It is made up of Carbon, Hydrogen, and Oxygen (CHO)
Benedicts Test:
It tests for reducing sugar, and if reducing sugar is present, the solution would become reddish (is there even such a word?) -orange precipitate. If not, it would just remain as blue.
Iodine Test
It tests for, as you all should know, for starch. So, if starch is present, the solution would turn blue-black, or if starch is not present, then the solution would remain brown/yellow, depending on the colour of the iodine at first. But I guess it would be better if you choose brown instead, to you know, just to play safe XD
Protein:
It is the main substance used for the growth of new cells, and the repair of damaged cells. It also provides energy when the body lacks fats, or carbohydrates.
It is made up of Carbon, Hydrogen, Oxygen, and Nitrogen.
Protein can never never be stored as it is TOXIC!!!! Thus, it is removed by the body via egestion, as urea in urine.
Biuret's Test
The biuret test is used to test for the presence of protein. If protein is present, the solution would change to violet (yeah!!! 0_0). If not, it wouls remain as blue.

Raw or cooked food?
So I'm back, finally I guess, from the terrible terrible 1 week holiday. Anyway, let's get back to the topic on hand. Oh, and 1 more thing, welcome to the era of Biology! .......
You know, I love sashimi so this would be quite an interesting topic to research on. Maybe if the results shows that raw food digest slower, I would consider going all cooked food. -_____-"'
According to a certain website, it states that raw food does not digest as easy as cooked food, thus if you want to feel full, do eat more cooked food, unless you're somehow on a diet.
It is believed that your body's own elimination system can eliminate all or most of the toxins in the cooked portion of your diet when eating more raw food. When you eat more cooked food you are eating toxins faster than your body can get rid of them so they back up causing disease.
While searching, I came across this websites that answers the second question- Should we eat raw food or cooked food?
Raw foods are rich in enzymes. Enzymes are needed for the digestive system to work. They are necessary to break down food particles so they can be utilized for energy. The human body makes approximately 22 different digestive enzymes which are capable of digesting carbohydrates, protein and fats. Raw vegetables and raw fruit are rich sources of enzymes.
Lack of digestive enzymes can be a factor in food allergies. Symptoms of digestive enzymes depletion are bloating, belching, gas, bowel disorders, abdominal cramping, heartburn and food allergies.
All of us loose our ability to produce concentrated digestive enzymes as we grow older. In cases where age is a factor, or where lack of digestive enzymes causes food allergies, supplementation may be helpful.
The more food that you can eat raw, the better.
If you do cook your food, the best way to cook food is to lightly steam, stew, or use a slow crock cooker. Eat as few over-processed and over-cooked foods as possible. The body has a difficult time digesting fried, pasteurized, barbecued, dried, and other over-processed and over-cooked foods which you find in boxed and processed foods.
Cooked food undergoes cooking (that's why it's called cooked food duhh..) and it uses heat. Enzymes are then destroyed in heat and it chemically changes foods from the substances needed for health into free-radicals and poisons that destroy our health!
. Enzymes are importanttt...
Therefore, the author of this blog strongly recommends raw food. Ye-ah. I love (L) raw food!

All of us loose our ability to produce concentrated digestive enzymes as we grow older. In cases where age is a factor, or where lack of digestive enzymes causes food allergies, supplementation may be helpful.
The more food that you can eat raw, the better.
If you do cook your food, the best way to cook food is to lightly steam, stew, or use a slow crock cooker. Eat as few over-processed and over-cooked foods as possible. The body has a difficult time digesting fried, pasteurized, barbecued, dried, and other over-processed and over-cooked foods which you find in boxed and processed foods.
Cooked food undergoes cooking (that's why it's called cooked food duhh..) and it uses heat. Enzymes are then destroyed in heat and it chemically changes foods from the substances needed for health into free-radicals and poisons that destroy our health!
. Enzymes are importanttt...
Therefore, the author of this blog strongly recommends raw food. Ye-ah. I love (L) raw food!
