I’m sure you would all like to ace your first chemistry test. Here’s how: 1. Test yourself on the topics below to see what you know and don’t know. 2. Review this packet in its entirety. Be familiar with each of the topics that were covered in the powerpoint presentation. 3. Write down what you don’t know yet. If you don’t know something, ask a friend or ask me. 4. If you are missing anything it may be available on the class website: http://www.chemistryacademy.com 9. Provide a balanced chemical equation for the combustion of 1. What is chemistry? isopropanol, C3H8O. 2.

What is matter?

3.

What is not matter? Give examples.

4.

What do chemists do?

5.

Where does chemistry fit in with the other branches of science?

6.

Name a branch of science more basic than chemistry.

7.

List the branches of science from basic to applied.

8.

What is our simple scientific method?

9.

Give an example of a positive and negative control

10. Provide two isomers of C3H8O by drawing their structural and skeletal formulas 11. Draw an ether with the formula C3H8O.

10. What is a synonym for a negative control?

12. Draw an amine, an alcohol, a carboxylic acid, an ester, and an amide. 13. Provide the molecular formula, skeletal formula, and functional groups present in leucine , shown below. 14. What organic functional groups are present in sodium chloride, NaCl? 15. Explain what is implied by the wedges and hatches used in the drawing of leucine. Does it contain straight chains, branched chains, or rings?

11. Why are negative controls important for most drug studies?

16. What happens to molecular formulas when double bonds and rings are used? 12. Provide a positive control for an experiment designed to produce bubble gum that blows big bubbles 17. Describe what you know about aristolochic acid, palytoxin, and the kahalalides. 13. How many bonds to the atoms C, N , H, and O form? 18. Draw a chart organizing chemistry into functional groups, 14. What is a useful mnemonic device for the bonding inorganic, and organic domains. pattern of hydrogen, oxygen, nitrogen, and carbon? 19. Define density, viscosity, and solubility. What role, if any, do 1. Who wrote The Skeptical Chymist? these play when solutions are mixed? 2.

What is a natural product and why are they important?

3.

Why is chemistry awesome?

4.

Compare and explain the flammability of liquids to gases.
