What type of reaction are each of these reactions:
Mg + CuSO4 —> MgSO4 + Cu

2HCI + Mg(OH)2 —> MgCI2 + H2O

AgNO3 + NaCI —> AgCI + NaNO3

(single displacement, double displacement or acid-base reaction)

Answer 1

1. Mg + CuSO4 —> MgSO4 + Cu

=> Single displacement reaction

2. 2HCI + Mg(OH)2 —> MgCI2 + H2O

=> Acid - base reaction

3.AgNO3 + NaCI —> AgCI + NaNO3

=> Double displacement reaction
