=Assignment #10 - Biomolecules=

Carbohydrates:

 * 2) Store energy, are present in DNA.
 * 3) Starch and sugar.

Proteins:

 * 1) Composed of amino acids.
 * 2) Hold up structure of cell walls.

 * 1) Not classified by chemical composition. Mainly made up of fats and waxes.

 * 3) Steroids and cholesterol.

Nucleic Acids:
The groups are: carbohydrates, proteins, lipids, and nucleic acids = = =Assignment #9 - Acids and Base= 1. A concentrated solution has a lot of solute, a dilute solution has little solute. 2. A strong acid completely reacts with water and the forward reaction dominates. On the other hand weak acids barely react with water and the reverse reaction dominates. 3. = = =Assignment # 8 - Equilibrium=
 * 1) Composed of chains of monomeric nucleotides.
 * 2) The nucleic acid stores and transmits genetic information.
 * 3) DNA and RNA.

1. As time elapses the concentrations of all reactants and products are constant even if the moles of the compounds change because the ratio of reactants to products will shift to even out the concentration. So therefore the equilibrium is dynamic because there can be different amounts of the compounds with maintaining a constant concentration. 2. When writing a equilibrium expression only use gases or aqueous compounds. The products go in the numerator position and the reactants in the denominator. Write the compounds in brackets with the coefficient in as an exponent. ex: H2(g) + F2(g) = 2HF(g) ... {HF}2 / {H2}{F2} N2(g) + 3H2(g) = 2NH3 .... [NH3]2 / [N2][H2]3 2O3(g) = 3O2(g) .... [O2]3 / [O3]2 3. Homogeneous Equilibria: N2(g) + 3H2(g) = 2NH3(g) ... [NH3]2 / [N2][H2]3 Heterogeneous Equilibria: CaCO3 (s) = CaCO(s) + CO2(g) ... [CO2] =Assignment #7 - Equilibrium= An example of equilibrium in the real world is water coming out of a faucet and going down a drain. The sink becomes only a little bit filled before it starts to drain, but the amount of water in the sink is constant because it is poring in at the same rate it is draining out. If the drain was somewhat clogged there would be more water in the sink at equilibrium, or if the water pressure was low there would be less water at equilibrium. The water coming out of the faucet would be the reactant in a chemical equilibrium and the water draining would be the product. This example is a dynamic equilibrium because the constant can either be low or high depending on the product to reactant ratio. = = =Assignment #6 - Reaction Rates= = = =Assignment #5 - Investigating Solubility and Immiscibility.=  1.) If an oil spill can be reached within hours it can be trapped in an area surrounded by buoyant booms with a skirt that hangs down and is attached to the buoys. Once it is contained, the oil can be collected by using boats that either scoop or suck the oil off the water. Spills can also be cleaned up by using absorbent sponges or, if the spill is far away from settlement, the spills can be lit on fire. To minimize the effect of oil spills is simple, we need to find oil alternatives so we don't depend on it as much.
 * Temperature: If you have three glow-sticks you can place one it hot water, one in cold, and one in room temperature. The hot water will speed up the reaction rate of the glow-stick and make it shine brighter, the cold water will slow down the reaction and it will shine dimmer. The one in room temperature will stay constant. []
 * Surface area:[]

 * Catalyst: Blood contains enzymes, which are a type of catalyst, if it is added to hydrogen peroxide it will speed up its decomposition. []
 * Concentration: If someone wanted to make a volcano for a science fair project they would have to make "lava" out of vinegar and baking soda. Depending on how quickly they want their volcano to erupt they would either increase or decrease the amount of baking soda added to the vinegar.

2.) Solubility is the ability of a substance to d issolve. Generally, an increase in the temperature of the solution increases the solubility, surface area and stirring do not effect solubility. Rate of dissolution is the rate of which a solute dissolves. Stirring, temperature increase, and increase of surface all speed up the rate of dissolution. = = =Assignment #3 - Greenhouse gas effect= The greenhouse gas effect is when the earth emits a specific frequency of infrared light and the gases in the atmosphere resonate off of it. The frequency ies are absorbed by the gas molecules and re-emitted back towards the earth, which increase the temperature of the earth.

I haven't heard much about global warming but i have heard that it was dis-proven because it never was proven in the first place. I also hear that if it is true that there wouldn't be a noticeable effect for a long time. = = =Assignment #2 - Ideal Gases in the Real World.= All Gas Laws can be explained through examples using balloons.

Boyle's Law: popping a balloon. If you squeeze a balloon to hard it will pop because by pressing on it you are trying to decrease the volume which would increase the pressure on the sides of the balloon, forcing it to pop. If pressure is increased, volume is decreased, and vice-versa, because according to Boyle, pressure and volume have an inverse relationship.

Gay-Lussac's Law: Heating Balloon. Heating a balloon, shown [|here], will cause it to pop. This happens because the law states that temperature and pressure are direct relationship. Increase the heat will increase the pressure in the balloon, causing it to pop.

Avogadro's Law: Blowing up a balloon. When you blow up a balloon you are increasing the amount of gas in it, which increases the volume of the gas. The law shows if you increase the amount, or moles, of gas in return you increase the volume, thus making the balloon larger. = = =Assignment #1-TED Talk.= [|Video], Anthony Alta on Growing New Organs

I chose the video because I'm very interested on new technology. I though it would be very interesting to see how it was possible to build something that had to be perfect enough to replace an actual organ in a human body. Anthony Alta talked about the process in which they remove cells from the actual organ that is being replaced. Next they look closely at what the cell is made up of, and then they regenerate it in large quantities. They add layers of the different kinds of cells to make the organ, it is then put into an "oven" which has the exact conditions of the human body. The organ is exercised until it is able to perform its job without help. Alta then explained how difficult and long this process is. After watching this video I was amazed at the fact that something like this is actually possible. I learned that it took a long time for organ to be grown, it also take a large staff for this to be done. I learned that even though this new technology can be a life saver it is still not ready to be used on real patients in need. Alta said that they still need stem cells from the heart, liver, nerve, and pancreas to be able t construct those organs.
