9.20. (i) PbS(s) +4H2O2(aq) → PbSO4(s) + 4H2O(l)
(ii) 2MnO4– (aq) +H2O2(aq) + 6H+(aq) → 2Mn (aq) + 8H2O(l) + 5O2(g)
(iii) CaO(s) + H2O(g) → Ca(OH)2(aq)
(iv) AlCl3(aq) + 3H2O(l) → Al(OH)3(s) + 3HCl (aq)
(v) Ca3N2(s) + H2O(l) → 3Ca(OH)2(aq) + 2NH3(aq)
(a) Hydrolysis reactions, (iii) (iv) and (v)
(b) Redox reactions (i) and (ii)
