Difference (from prior major revision) (no other diffs)

Changed: 3c3

1. Besides actually do a limiting reactant problem calculation, what information in the lab indicated that you had to do a limiting reactant calculation to determine the mass of the products?

1. Explain what a hydrate is.

Removed: 5d4

2. Explain what a hydrate is and what happens to the hydrate to make the solution.

Removed: 7d5

3. What would happen to the percent yield if you did not leave the product in the dryer long enough?

Added: 8a7

2. Was it important to know that your reactants were hydrates, explain your reasoning.

Changed: 10c9,26

3. What information(s) in your lab indicated to you that you must do a Limiting reactant calculation to determine the amount of products?

4. What procedure/observation to you use from the lab that helped you determine which product you are/were doing a percent yield for?

5. What could be a possible reason why you obtained a percent yield greater than 100% (can't use mass wrong, calculated wrong, did not weigh correctly).

6. If one of your reactants produce a colored solution, how would that help you in determining if it was the limiting reactant or not? Explain.
