1. Double displacement

2. Decomposition

3. Synthesis

4. Double displacement

Further explanation

Given

Some reaction equations

Required

Type of equation

Solution

4Al + 2Fe3N2 → 4AlN + 3Fe2

Double displacement

Cations and anions switch places

2PbSO4 → 2PbSO3 + O2

Decomposition

Single compounds break down into 2/more products

H2O + SO3 → H2SO4

Synthesis

Two or more reactants combine

3ZnS + 2AlP → Zn3P2 + Al2S3

Double displacement

Cations and anions switch places
