Wiki Assignment 10 (Last one!) Biomolecules The goal of this last wiki is to familiarize yourself with the types of biomolecules we will talk about next week. For each of the types of biomolecules, answer the following questions:

1. What is the molecule made of? 2. What is/are the function(s) of the molecule? (What do they do in the body?) 3. What are 2 examples of the biomolecule group?

The groups are: carbohydrates, proteins, lipids, and nucleic acids

Wiki Assignment 9: Concentrated vs. Dilute and Strong vs Weak. Answer the following questions: 1. What is the difference between a concentrated solution and a dilute solution? 2. What is the difference between a strong vs weak acid solution? 3. Come up with some sort of representation of the following combinations: A concentrated solution of a strong acid, a concentrated solution of a weak acid, a dilute solution of a strong acid and a dilute solution of a weak acid. This could be drawn in a word document and uploaded to the wiki (instructions for uploading files to the wiki will be posted by Friday) or some sort of written description. You must include what is present in solution (use the symbolism HA for the acid).

Wiki Assignment 8: Equilibrium 2 Answer the following questions about equilibrium 1. Explain why, once a chemical system has reached equilibrium, the concentrations of all reacts and products remain constant with time. Why does this constancy of concentration not contradict our picture of equilibrium as being dynamic? 2. Describe how we write the equilibrium expression for a reaction. Give three examples of balanced chemical equations and the corresponding expressions for their equilibrium constants. 3. Give balanced chemical equations and write the corresponding equilibrium constant expressions for examples of both homogeneous and heterogeneous equilibria.

Wiki Assignment 7: Equilibrium

Come up with your own example of an equilibrium system and relate it to chemical equilibrium. Make sure to thoroughly explain how your example matches with chemical equilibrium.

Wiki Assignment 6: Reaction rates Find an example demonstrating how each of the following affects the reaction rate and explain the effect using collision theory: Concentration Temperature Catalyst Surface Area You many NOT use any of the examples we talked about in class. Videos or written descriptions are fine to use, but make sure to cite where you find your information.

Wiki Assignment 5: Investigating Solubility and Immiscibility Your Task: 1.**__Immiscibility__** is when two liquids will not mix with each other. One potential danger when this happens is when there is an oil spill on the ocean. When an oil spill occurs, the oil floats on the water and spreads out, destroying ocean life and ruining shorelines. What is done to clean up oil spills and minimize their destructive effects on the environment?

2. **Solubility versus Rate of Dissolution** Perhaps it is because both solubility and rate of dissolution are affected by temperature, but confusion often exists about the difference between these two concepts and the effects that temperature, stirring, and surface area have on them. -Define Solubility and Rate of Dissolution -Explain how temperature, stirring, and surface area affect each concept.

Your posts are due by 9pm on March 7th.

Wiki Assignment 4: Wonderful Water Our next unit we will be covering liquids and solutions, and we will spend some time talking about water. Water is clearly a very important molecule to any living thing, but it is also a very unique molecule compared to similar molecules. Your assignment is to find out a little more about what makes water such an unusual molecule.

Your task: 1. Research and list 5 physical properties of water AND list if that property is unusually high, low, or similar to other molecules. (only one of your properties can be melting or boiling point) 2. Define each property you list. 3. Cite where you find your information

Wiki Assignment 3: A Global Warming? We can't go through our gases unit without talking about the chemistry of our atmosphere. The topic of global warming/climate change has been a source of debate and politics for many years now. There is a lot of misunderstandings surrounding the topic of global warming and atmospheric chemistry. This assignment will hopefully bring some clarity to the debate.

The assignment: 1. Read the following article related to the science behind the greenhouse effect: (From ChemMatters Magazine, October 2003. Published by the American Chemical Society and available on-line at www.chemistry.org/education/chemmatters.html) 2. Explain (on the atomic level) how the greenhouse effect works. 3. List any statements or opinions you have heard about the global warming debate that may or may not be scientifically accurate. (Need at least 2). You could list what you've heard about the potential hazards of global warming, why people say global warming is not happening, or anything else related to this topic. We will examine these statements in class on Wednesday, Feb 17.
 * Posts must be made by 9pm on February 14.**

Wiki Assignment 2: Ideal Gases in the Real World In this assignment, your task is to find three examples of the gas laws in the real world. Your examples could be video clips, pictures, articles, or simply observations that you make. 1. Find three situations/examples that demonstrates three different gas laws. 2. Either upload, link or embed the examples to your wiki. (Cite where you got your pictures, unless you took the picture) 3. Using 2-4 sentences, explain how what you chose demonstrates a gas law -Use the kinetic molecular theory to help your explanation

1. Go to @http://www.ted.com and watch a science talk that interests you. What to post on your page: -A direct link to the talk you watched -Why you chose that talk -Brief synopsis of the talk -Your reaction to the talk/what you learned
 * 1) 1--There is a lot of interesting research being done in all areas of science. This first assignment is for you to investigate some of this research. The TED organization is a nonprofit organization dedicated to sharing ideas in technology, entertainment and design. TED has conferences throughout the year where they bring in the top researchers to speak about what they are working on, then post the talks on their website for all to see. Here is your assignment:
