1. Study the questions found HERE

2. Be able to calculate the thickness of a piece of aluminum foil if you’re given its density and you can measure its weight on a triple beam balance.

3. Be able to calculate the area of a piece of aluminum foil if you know its density and thickness.

4. Know how to calculate the volume of one mole of water, given that the atomic weights of H = 1 and O = 16. ( For help, see Problem 4( j ) HERE )

5. Know how to calculate the volume of a drop of water using a plastic pipet.

6. In a chemical reaction involving two metals, know how to recognize which metal has gained electrons (for help with this, go HERE ).

7. Know how to calculate the % by weight of potato chips there are in a bag of potato chips.

8. Know how to write the chemical reaction that takes place when calcium metal is added to water. HELP!

9. Know how to write the chemical reaction that takes place when acid neutralizes a base.

10. Recognize when metals gain or lose electrons in chemical reactions with other metals. Know which metal gets oxidized, which metal gets reduced, and how to figure out which metal is more reactive than another. HELP! MORE HELP!

11. Know how to prepare a solubility graph if you are given solubility data for a substance at different temperatures, and be able to work problems based on the graph (for example, see TRY SOME PRACTICE PROBLEMS HERE).
