Here are the Questions/problems for Type of Chemical Reaction Lab
Part I
Answer these questions using information from your data table and balanced complete chemical rxns.


1. What is the color of the copper (II) oxide?

2. What is the color of magnesium oxide? What observation would indicate that a chemical reaction occurred?

3. What observation did you not see with the copper that you did with the magnesium to indicate that a chemical reaction occurred? Did this mean that the copper did not go through a chemical reaction, explain?

Decomposition (not including Hydrogen peroxide reaction)

4. What gas was produced and how do you know it is that gas? What color and phase is CuO?

5. What was the other product that you observed? Is it one of the products that you wrote in the chemical equation? If it where did it come from?

Single Replacement

6. What gas was produced in the chemical reaction with zinc and hydrochloric acid? How did you know it was that gas? What is the phase and color of zinc chloride?

7. What color was the copper (II) sulfate solution? What happened to the liquids color as the reaction occurred? What color solid did you form? What is this solid?

8. From your experiment, what causes the blue color in the copper (II) sulfate solution?

9. From your observation, can you tell if zinc sulfate is aqueous? If it is, what color is the solution?

Double Replacement

10a. How do you know that this reaction occurs?

10b. How do you know that this double replacement reaction occurred?

10c. How do you know that this did not occur?

Part II

Write the balanced complete chemical equation for the following reactions. Then do a net ionic reaction on the reaction.
1. Copper metal (elemental form) is added to a solution of silver nitrate. to produce copper (II) nitrate solution and elemental silver
2. A solution of silver nitrate and calcium chloride is added together to produce silver chloride solid and calcium nitrate.
3. Chlorine gas (elemental form) is bubbled through a solution of potassium bromide to produce potassium chloride solution and elemental bromine.
