Explanation / Answer

1) Ba(ClO3)2 ---------- BaCl2 + 3O2

a) Decomposition reaction. Here one compund splits into two

b) Redox: Cl gets reduced from +5 in Ba(ClO3)2 to -1 in BaCl2. while, oxygen gets oxidised from -2 to 0

2) CaO + CO2 --- CaCO3

Combination (synthesis)

3) NaNO2 + HCl -------- NaCl + HNO2

Double displacement: AB + CD ---------- AD + CB

4) ZnSO4 + Mg ------ MgSO4 + Zn

a) Redox: Zn gets reduced from +2 in ZnSo4 to 0 while Mg gets oxidised from 0 to +2

b) Displacement (Single): AB + C ---------- AC + B
