 Wiki Assignment 10: Carbohydrates are made of sugars, starches and cellulose. They are also made of the same 3 compounds carbon, hydrogen and oxygen. Carbohydrates are the main form of energy the body uses. Carbohydrates are not involved in weiht gain unless eaten too much. Carbohydrates are used to store enery in the muscles for excersize. Carbohydrate is also the primary energy source of brain, nervous tissue, retina, kidney, and red blood cells. Biomolecule examples would be glycouse and celulose. Proteins are mad o amino acids arranged in a linear chain. Proteins are one of the three main macronutrients. Protein is necessary for repairing body tissue and building muscles. 2 biomolecule groups involved in protein are the aminno acids and starches. Lipids are naturally occurring molecules that contain many calories in a small space. Examples of these are fats, waxes, and sterols. Lipids help by keepin metabolism maintained and by storing energy for later use. Biomolecule examples are carbon, hydrogen, oxygen, fats and glucose. Nuclic acids ar mostly made up of DNA and RNA. Nucleic acids helps determine our genes.Nucleic acids have hydrogen, carbon and oxygen involved with the DNA and RNA process.

Wiki Assignment 9: 1. A concentrated solution is a solution in which a relatively large amount of solute is dissolved in a solution.With a solution being concentrated that means there are more collisions involved in the reactions which means a higher reaction rate. A dilute solution is a solution in where a relativley small amount of solute is dissolved. 2. A strong acid solution is an acid in a solution that completley dissociates to produce H+ ions and the conjugate base. A weak acid soluion is an acid in a solution that dissociates only to a slight extent in an aqueous solution. 3. In a dilute solution of strong acid HA There are few H+ and A- ions in the solution. Then when these 2 react it forms a new substance and a new charge. In concentrated solution of strong acid there are many H+ and A- ions all in the solutiion clumped together which means that there are many collisions which equals a higher reaction rate which then means a high concentration. In a dilute solution of weak acid there are very few H+ and A- but then in the solution there is also HA bonded together. In a concentrated solution of weak acid HA there are H and A but also many bonded pairs together

Wiki Assignment 8: Equillibrioum 2- 1. Once a chemical system has reached eqiullibrium the concentrations of all reactants and products reamian constant with time because the rate of the products is equal to the rate of reactants. The reason equillibrium is dynamic is becaue chemical equillibruim is a dynamic state where the concentrations of all reactants and products remain constant. There is also no net change due to the fact that forward and reverse reactions are always happening at the same time even afte a chemical system reaches equillibrium. Likewise, when there is a forward and reverse reaction there isthe same rate and due to that consistency of concentration equillibrium is a dynamic state. 2. An equillibrium expression is written as followed: The ratio of the concentration of the products wih ther coefficients over the concentration of reactants with their coefficients at equillibrium. Each concentration is raise to the power correspnding to the coefficient in the balanced equation. Also note hat solids and liquids are not used in the expresion. H^2(g) + F^2(g)=2HF(g) equillibrium expression is [HF]^2/[H^2]x[F^2]=K N^2(g) + 3H^2(g) = 2N^3(g) equillibrium expression is [NH^3]^2/ [N^2]x [H^2]^3=K 2O^3(g) =3O^2 equillibrium expresion is [O^2]^3/ [O^3]^2=K 3. Heterogenous equilibira= CaCO^3(s)= CaO(s) + CO^2(g) equillibrium expression is K=[CO^2] Homogenous equilibria= 2O^3=3O^2 equillibriom expression is [O^2]^3/[O^3]^2=K

Wiki Assignment 7: An example of an equillibrium system would be kicking a soccer ball back and forth with a friend but one kicks it with their right foot and the other person kicks it with their left foot. This is an example of an equllibium system because they are opposite to eachother and exactly balancing the 2 processes. This is matched with chemical equilibrium because it is a dynamic state where the ball moving back and forth with the same amount of strength used to kick the ball which results in the product and reactant remaining constant. This also results in no net change. With this experiment it can be thought of as the rate of the forward reaction is equal to the reverse raction just like the ball gpoing back and forth. This experiment is just one way in which this equilibrium process can be used another example is ping pong where the ball goes back and forth and there is no net change because the ball is always being hit back anf fourth which is a equillibrium system.

Wiki assignment 6: Concentration:[|Reaction rate concentration] With this example it shows that the more concentrated the hydrogen peroxide is the faster the reaction rate and he tries the experiment with 3% and 30% on toothpaste and there is a major difference between the reactions. Temperture:[|Temperture reaction rates] With this example the video shows how as the temperture of a reaction increases the rate of the reaction increases by using light sticks at a different temperture. With that the one at the highest temperture as the most molecules colliding which means the reaction rate increases. Catalyst:[|catalyst reaction rates] With this example its shows how adding a catalyst to a reaction increases the rate of that reaction. In this experiment there is elephant toothpaste and some solutions. When the non consumed solution is put on the toothpaste the reaction happns very fast with the more solution there is acting as a catalyst. Surface area:[|Surface area reaction] With this experiment it shows how surface area of of the reactants increases the reaction rate.The chemist puts lakapodium powder on a nceramic plate as used in oiur labs. He then puts the plate on the bunsen burner and it does not burn very well. Then he increases the surface area of the powder and puts it on the bunsen burner and huge flame occurs. With that it shows how the increase of surface area affects reaction rate.

Wiki Assignment 5:

Oil spills are very hazardous to not only people but also animals and oil spills are something preventable. There are ways in case of oil spills to prevent the spread of oil among the people and animals. One way is to place a boom in the water. Booms are placed near the shores of the ocean and they collect any oil that crosses its path. Skimmmers are also used which are boats used that pick up oil when the boat meets the oil. The last major way peole treat the oil is by dropping chemicals into the ocean with the use of airplane. This way is effective but this can also hurt the animals. [|Oil spills cleanup]

Solubility (also known as solute) is a the property of a solid, liquid or gas substance that can be dissolved in a homogenous solution Solubility and tempertures relationship is dependent on one another because when temperture is increased the shape of molecule can change. Stirring will not have anaffect on solubility by stirring would be neceesary to stir kool aid or else it will not dissolve and it will taste really bad. The surface and solubility is not very relative to eachother but this is what ties into temperture because when a substance changes its form the surface also changes. The rate of dissolution is the rate of which the speed of something goes into and dissolves. With the rate of dissolution if temperture increases the rate of dissolution inctreases. Stirring increases the rate of dissolution also. Then the more surface area there is the rate of dissolution also increases.

//Wiki Assignment #4: Water kis a very intersetin molecule. It can take the space of both a solid and a liquid and without water we would not be able to live. Water also makes up 70% of our body. Also, when we loose weight we can onlt lose .5 pound per day the rest is water weight lost. Water is composed of oxygen and hydrogen and thats why it has the symbol H2O. Water is everywhere we look whether its the ocean or the icicles when its winter in minnesota. Some researchers say that by 2025 there will be a shortage of water in the world compared to too much water back in the late 1990's. Water is trely an amazing thing that makes everyday worth living.

Wiki Assignment #3: The greenhouse affect is a good thing that really helps the way the earth works and is necessary for it to work like it does. It is caused by the atmosphere containing gases that absorb and emit infrared radiation. Greenhouse gases trap the heat within the surface and cause heating at the surface of the earth, With this it helps keep a constant pressure but some think that this could be the cause of global warming.I do not think global warming is real although with the green house effect in play. In the recent months the crediblity of the scientists supposedly proving this we are questioning whether they just made all this research up. Also if this is false how are there snow storms all over the nation and how come I had to cut my vacation this weekend short because of snow :(. We have had the coldest tempertures in recordance and we are still paying these people millions for what? proving something that is not real come on the facts show that global warming is not real and so does real life. Also, Al Gore made a movie that shows what he says is global warming but he cannot support his information and he has no idea what he is talking about he just acts like he knows whats going on but rather his information shows how global warming is not real.P.S. sorry about the underlinings my computer is messed up and sorry about gores accusations im just being a good chemist and observing the world.

demonstration**// //**- This demonstrates boyle's law because as the liquid nitrogen is sealed in the plastic bottle the liquid nitrogen is changing into a gas. As the volume increases the pressure also increases wich causes this explosion. With kinetic molecular theory as the tiny paricles are in random motion and as the volume increases there is a lesser chance for those particles to collide.**//
 * boyles law

[|//**Charles law demonstration**//]//**- This demonstration shows that temperture decreases when liquid nitrogen is poured onto the baloon and when temperture decreases the average kinetic energy is also decreased. Yet as the temperture decreases the mass of the balloon decreases causing in more collisions betweeen the particles in the balloon.**//

[|//**gay-lussacs law demonstration**//]**//- This demonstration shows that as the coke is being heated up and not shaken the person is determining whether or not the same affect will happen. As the temperture increases so does the volume causing the bottle to explode. Overall, involving kinetic molecular theory the increase in volume causes less particles colliding but, as the temperture increases that causes more friction.

Ted Talk Assignement #1://** [|**How to live before you die incorporating science**] I chose this talk because to this man has something he believes in which is science and also something he loves to do which is technology incorporating science. This man had a goal and he stuck with it because he knew what he loved and that is what he enjoyed. He rolled with the punches of what life gave him and turned them into learning experiences which makes him one of the most successful men in America because he listened to not what others thought but rather, what he thought. In this video Steve Jobs talks about 3 very important things. He talks about how bad things can be good thinks, about his past and life experiences, and how death is the best invention in the world. He talks about how he was fired from the company he made and how he reacted and made 2 other multimillion dollar companies and he says "after i showed apple what i had done i learned what true success was and that is the best feeling in the entire world." He said how death is the best invention in the world because it teaches us how we only live once. But, the most important thing he talked about in my opinion is saying of if he did not like something he would change even if it meant losing something important to him just so he could like himself and be successful. When I listened to this talk about how technology and science changed his life i thought he was crazy. When i look at it now, he was getting to something and that taught me to follow your dreams and never let anyone tell you what you can and cannot do in your life. This is an exceptional video and it shows how one man's passion for science taught hi life lessons he will remember forever.
