=Wiki Assignment #10= 1) Carbohydrates are carbon, hydrogen, and oxygen bond together in the ratio: Cx(H2O)y, where x and y are whole numbers that differ depending on the specific carbohydrate to which we are referring. Proteins are large [|molecules] that may consist of hundreds, or even thousands, of amino acids. Amino acids all have the general structure. Lipids contain even numbers of carbon atoms in straight chains commonly C14 to C24, and may be saturated or unsaturated, and can contain a variety of substituent groups. Nucleic acid is made of alternating sugar and phosphate. 2) Carbohydrates are the main energy source of the body. Proteins comprise approximately 50% of the dry weight of cells and fill a number of purposes. Lipids are there to help store the energy that we get from Carbohydrates. Nucleic acids store and transmit genetic information and use that information to direct the synthesis of new protein. 3) Two types of Carbohydrates are pasta and pizza. Two types of proteins are meat and beans. Two types of lipids are cholesterol and seafood. Two types of Nucleic acids are DNA and RNA =Wiki Assignment #9= 1) The difference between a concentrated and a dilute solution is that in a concentrated solution there is more of the solute in the solution. In a dilute solution there is more of the solvent in the solution.

2) The difference between a strong and a weak acid is that a strong acid completely reacts with water to make (HA)-. When the forward reaction dominates there is an equal amount of H+ and A- in the solution. A weak acid is when the reverse reaction dominates and the initial amount of (HA)- will be about the same in the final amounts. There would only be a little amount of H+ and A- in the solution.

3) =Wiki Assignment #8= 1) When a chemical system is at equilibrium, all the concentrations are constant because the reactants are turn to products at the same speed as the products are turning into reactants. This means there is no change in their concentrations. This process is dynamic because there is still a reaction going on although the two are constant. 2) To write the equilibrium expression for a balanced chemical reaction equation is: looking at the different substances, looking to see what state they are in. This is important because only gaseous stated substances are included in the equilibrium expression; solids and liquids are not included. To write and expression- which is the right side of the double arrows substances go on top that are divided over the left side substances. Some examples would be: 4O (g) double arrows 2O(g) + 4O (g) Expressions: K= [O]2[O]4 3) Homogenous 2FeCl2(aq) double arrows Fe2(aq) + 2Cl(aq) K= [Fe2] [Cl]2 / [FeCl2]2 Heterogeneous Fe(OH)2(s) double arrows Fe2+ (aq) + 2OH- (aq) K= [Fe2+][OH-]2 =Wiki Assignment #4 - Properties of Water= 1) Pure water has a pH of 7; this is right in the middle of it. pH is a measurement of how acidic or how basic a solution is. 2) Weight: 62.416 pounds per cubic foot at 32 ° F, I believe that this is high but I am not sure. This is how much water weighs at 32 ° F. 3) Water boils at 212 ° F, this is high. This is the point that water will change into steam. 4) Water has a very high surface tension, this is very high. Surface tension is what causes the surface portion of liquid to be attracted to another surface. 5) Water is called the "universal solvent" because it dissolves more substances than any other liquid, this is high. This tells you that water can dissolve almost anything. "Water properties: Water Science for Schools: Physical and chemical water properties." //USGS Georgia Water Science Center//. Web. 21 Feb. 2010. . =Wiki Assigment #3 - Greenhouse Effect= The  greenhouse effect  is the rise in temperature that the Earth experiences because some gases in the  atmosphere  such as water vapor,  carbon dioxide ,  nitrous oxide  , and  methane  trap energy from the sun. Without these gases, heat would go back into space and Earth’s average temperature would be about 60  ºF  colder. Because of how they warm our world, these gases are referred to as  greenhouse gases  . These greenhoue gases bounce off the ozone laver and hit the Earth thus warming it up and keeping us warm. I have heard that global warming is going to flood the world because the glaciers are melting away, but we are still getting massive amounts of snow up here in Minnesota and it also is still cold. I would live to see where they are getting the info that the world is heating up because I can't see it here. I think like me that people don't think that it is happening is because they are not seeing it in their own communities around them. I have heard that the global temp is to go up 1.1-6.4 degrees celsius which is 2.0-11.5 degrees fahrenheit. which sounds like a lot but I am not seeing it. = = Wiki Assigment #2- Examples of Gas Laws [] [] [] Picture one which is the bottle with the two balloons in it is an example of Boyle's law. This is an example of a diaphragm which helps make you breath through moving up and down to either increase or decrease you lungs capacity. This is an example because the temperature stays the same even though the pressure decreases and the volume increases which is what is stated in Boyle’s law. Picture two in a pressure cooker which cooks food by using the water that you put in there to make steam to heat food up for canning. This is an example of Gay-Lussac’s law which states that if you in the temperature the pressure will increase but the volume stays constant. This is shown in the pressure cooker because the pot stays the same size but the pressure increases as you heat in up. The third picture is a hot air balloon. This is an example of Charles’ law because the pressure stays the same but the volume needed to make the air balloon fly increases as you heat up the air in the balloon. As it states in Charles’ law as the temperature increases the volume also increases but the pressure stays the same. =Wiki Assignment #1-TED Talk= [] I chose this video because this is a house hold item that people use every day and this think helps to keep the water you drink clean. In this talk he tells us how long it took fresh water to get to teh superdome after katrina which was five days. He also talked about how people would shot ofthers just so that they could have water. He said that after he had failed he finally came up with the right idea on what to make. thus the "Lifesaver bottle" was made. Before this the best filters could filter down to 200 nm, and that is the size of the bacteria. The smallest virus though is 25 nm, but his "Lifesaver bottle" is up to 15 nm. The "Lifesaver bottle" is useful for up to 6,000 L and will a utomatically shut off when you have reached that so not to harm the user. My reaction to this is that everyone can have safe drinking water no matter where you live or what kind of water is around you. By using the "Lifesaver bottle" we all can have safe drinking water
