Carbohydrates are composed of Carbon, Hydrogen, and Oxygen. They are used to supply the body with energy so it can perform day to day tasks. Examples of Carbohydrates are glucose and cellulose. Sources of carbohydrates are in pasta and potatoes. Proteins consist of Carbon, Nitrogen, Hydrogen, and Oxygen. Proteins are used to help rebuild muscle. Proteins are found in peanut butter and meat. Two examples of Proteins are amino acids and starches. Lipids are formed from long carbon chains. Lipids are loaded with energy but can cause heart issues. Two examples are fatty acids and glucose. Nucleic Acids are made up from carbon and nitrogen. Nucleic acids are used by the body to make DNA which determines the make up of your body. Two examples of Nucleic acids are Ribonucleic Acids and Deoxyribonucleic acids.

1.A concentrated solution is a solution where the amount of solute is greater than the amount of solvent. A Dilute solution is the opposite, the amount of solvent is greater than the amount of solute. 2.The difference between a strong and weak acid is how well it reacts with water. A strong acid reacts completely with water but a weak acid does not. 3. Once a chemical equation reaches equilibrium, the concentrations of the reaction and product will stay constant. This is because the reactants are becoming products in the forward reaction at the same rate the products are turning back into the original substance in the reverse reaction. Since the rate of both is the same, once the equation reaches equilibrium both concentrations will remain constant. Our picture of equilibrium being constant is not changed because the forward and reverse reactions continue to happen even after equilibrium is reached. To calculate the equilibrium constant you take the product of the concentrations of the products is divided by the product of the reactants. If there is a coefficient in front of the particle in the equation than you use the coefficient as an exponent while calculating the equilibrium. 1) 2NO2 N2O4 K = [N2O4] [NO2]2 2) 2O3 3O2 K = [O2]3 [O3]2 3) H2 + F2 2HF K = [HF]2 [H2] [F2] Homogeneous H2 (g) + I2 (g) 2HI (g) K = [HI]2 [H2] [I2]

 * __Solubility and Immiscibility__**

To get rid of oil that is spilled on water, proffesionals use booms to quarentine the oil spill into a desgnated area. Special boats called skimmers then come by and "skim" the water and suck out the oil. The oil is then stored and disposed of properly. Another way to get rid of oil spilt on water is to set it on fire in a controlled situation and let it burn away. One final way to treat an oil spill is to use chemicals to break the oil down so it is less harmful to the environment.

Solubility is the ammount of a solute that can be fully disolved in a solvent. The rate of dissolution is the ammount of time it takes for a solute to dissolve in a solvent. Increasing temperature increases the solubility as well as the rate of dissolution. Stirring a mixture increase the rate at whcih the solute dissolves. Increasing the area increase the solubility becasue there is more solvent for the solute to mix with.


 * __Properties of Water__**

1.One property of water that makes it unique from other substances is called cohesion. This is when the negativly charged oxygen molecules in water are attracted to the positively charged hydrogen molecules. This causes water molecules to be attracted to other water molecules. 2.Water can be found naturally in all three states of matter; solid, liquid, and gas. Water is the only known substance to be able to do this in nature by itself. 3.Another property of water is that it has something called surface tension. Surface tension is caused by cohesion of water, causing the molecules ontop of water to come together and form a sort of barrier, allowing light objects to float ontop. Water has the second highest surface tension, Mercury being higher. 4.Water also has the highest heat capacity. This means it takes the most energy to raise the temperature of water up one unit. Water's heat capacity is 1 Kelvin per gram per degree celcius. 5.Unlike many other substances, when water is frozen it expands. Few other liquids share this trait. Water expands up to 9% when it is frozen.

 * __Wiki Assignment 3: Global Warming__**

The Greenhouse effect is caused by none other than the greenhouse gases. When light from the sun shines down on earth, it passes through the atmosphere in ultraviolet rays and is absorbed by the ground. Some of this light is the bounced back up into the atmosphere in an infrared form. The light is now vibrating at a higher frequency, one that is equal to the frequency of the greenhouse gases. Since both the light and the greenhouse gases have the same frequency, the light is bounced back to the surface, warming it up, also known as global warming.

One opinion I have heard was that Global Warming is not something we need to worry about. Earth is simply going through a climate change, which has happened in the past, and no change needs to be made. Another opinion on Global Warming is that the sun is either increasing in temperature or is moving closer towards earth, both of which would increase earth's average temperature.

[|Example 1] This video is an example of the Gay-Lussac Law. According to this law, when you increase the temperature of the molecules, the pressure will increase. In this video, a bottle of Axe Body Spray is set on fire in a campfire. The bottle was under pressure and the fire heated the action up. The molecules bagan to bump into eachother more because of the heat and the pressure was increased. As a result, the can exploded.

[|Example 2] This video demonstrates Charle's Law. As you decrease the temperature of a gas, the volume will also decrease. In the video, the proffesor demonstrates the law by pouring liquid nitrogen on a latex glove filled with air. You can clearly see the balloon gets much smaller, proving Charles Law is accurate.

[|Example 3] According to Boyle's Law, if you decrease the volume of a gas, the pressure increases, or the other way around. In this video, the guy decreases the volume of the gas in the tube. This increases the pressure and causes the rocket to shoot off the end.


 * __Wiki Assignment 1: TED Talk__**

[|Aliens, Love -- Where are they?]

I chose this talk because I have always been fasinated by the idea of Aliens. I'm pretty sure it always started with outer space video games but I've always just been so amazed by the idea of life somewhere else besides earth. The movie Independance Day made me wonder even more and I truely do believe there is other intellegant life in the universe. The Talk consisted of John Hodgman speaking about the posssibility that there is already aliens living among us. Maybe the ordinary could actually be the extraordinary and we just haven't realized it yet. Hodgman gives several examples of times in his life that could possibly point in the direction of aliens living here on earth without us knowing it. There was really no scientific evidence behind Hodgman's talk. He had several stories about so called "close encounters" but doesn't back them up with any true facts. Putting that aside, Hodgman truly does an amazing job at making you think about your life and examining any odd experiences that may be hard to explain. He puts an odd theory of Aliens living here on earth into a fun and enjoyable talk that will leave you thinking about E.T.'s at least a little.
