1) 2 P + 5 O2 = P2O5 (compound reaction).

2) P2O5 + 3 H2O = 2 H3PO4 (compound reaction).

3) 2 H3PO4 + 3 Ca (OH) 2 = Ca3 (PO4) 2 + 6 H2O (exchange reaction).

4) Ca3 (PO4) 2 + 3 CO2 + 3 H2O = 3 CaCO3 + 2 H3PO4 (exchange reaction).

5) H3PO4 + Al (OH) 3 = AlPO4 + 3 H2O (exchange reaction).

1) SO3 + ZnO = ZnSO4 (compound reaction).

2) ZnSO4 + 2 NaOH = Zn (OH) 2 + Na2SO4 (exchange reaction).

3) Zn (OH) 2 = ZnO + H2O (decomposition reaction, conditions: temperature)

4) ZnO + 2 HCl = ZnCl2 + H2O (exchange reaction).

5) ZnCl2 + CO2 + H2O = ZnCO3 + 2 HCl (exchange reaction).
