Place ~1 mL (~1/2 inch) of 0.1 M CuSO4(aq) into a small test tube (~4" in size).
Add a small piece of zinc metal to the solution.
Let it sit for 10 to 15 minutes, then record your observations.
The images below shows the result of adding Zn to a CuSO4 solution.
Complete the table by selecting the observation that most closely matches the evidence you observed that indicates a chemical change occured. Then select the correct reaction type.

From the procedure
In the fume hood, turn the blower on, but leave the light off.
Obtain a small strip of magnesium metal ribbon.
Using proper techniques, thoroughly heat the end with the CuSO4 over a Bunsen burner for about half a minute.
Using crucible tongs or a test tube holder, hold the tip of the magnesium ribbon in the hottest part of a Bunsen burner flame. As soon as the magnesium ignites, look away to avoid eye damage.
When the reaction is complete, examine the residue and record your observations.
The video below shows the reaction of magnesium and oxygen, a black solid that remains after the reaction falls away.
