1. Dissolve three grams of powdered copper (II) sulfate in 20 ml of distilled water in a beaker.
2. Place a strip of zinc metal in the water. Wait at least 15 minutes for a reaction to occur.
3. Observe and record what happens to the zinc.
4. Write the equation for the reaction; identify the type of reaction.
What type of reaction is this? Is this an exothermic reaction or endothermic reaction?

Yes, Zn is higher on the activity series than Cu, so it will displace the Cu in CuSO4. Pure Cu will be deposited while the Zn becomes ZnSO4. This is a single replacement reaction.

CuSO4 (aq) + Zn (s) --> ZnSO4 (aq) + Cu (s)
which would be a SINGLE DISPLACEMENT reaction, and it would occur on its own because Zn is MORE reactive than copper. this means that you would not need to add heat but it would release heat making it an EXOTHERMIC reaction.
