The Synthesis of Copper Sulphide

1) Purpose:
How will the elements react? How will the compound they form react?

2) Hypothesis:
If the elements and compound react, then the elements will have to be a mixed powder and it will have to be heated because it is difficult for solids to react.

3) Safety Precautions:
Wear safety spectacles.
Be able to access fume hood.
Allow tube to cool completely after heating it to prevent burning.
