a) 1) 2P + 3Mg → Mg3P2 (compound reaction);
2) Mg3P2 + 6H2O → 3Mg (OH) 2 + 2PH3 (exchange reaction);
3) 2PH3 + 4O2 → P2O5 + 3H2O (substitution reaction);
4) P2O5 + 3H2O → 2H3PO4 (compound reaction);
5) 2H3PO4 + 3Ba (OH) 2 → Ba3 (PO4) 2 + 6H2O (exchange reaction).
b) 1) Al2O3 + P2O5 → AlPO4 (compound reaction).
c) 1) P2O5 + 3K2O → 2K3PO4 (compound reaction).
