Question

State whether a displacement reaction will occur. Also, write the chemical equation.

Zinc sulphate and iron

Copper sulphate and zinc

Zinc sulphate and copper

Answer 1

Answer:

1. ZnSO4 + Fe - - - - - FeSO4 +Zn

2. CuSO4 +Zn------ZnSO4 +Cu

3. ZnSO4 +Cu - - - - - ZnSO4 +Cu

Explanation:

1. Iron that is ferrous is more reactive than zinc so it will remove zinc in the 1st reaction and form ferrous sulphate.

2. Zinc is more reactive than the copper so it will remove copper and form zinc sulphate.

3. By 2nd explanation no reaction will happen
