Explanation:

(a) 2H2(g) + Cl2(g) → 2HCl(g)

(b) 3Zn(s) + 6HCl(aq) → 3ZnCl2(aq) + 3H2(g)

(c) 2KClO3(s) → 2KCl(s) + 3O2(g)

(d) Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)

(e) Cu(s) + 2H2SO4(aq) → CuSO4(aq) + 2H2O(l) + SO2(g)

(f) 2Al(s) + 3H2SO4(aq) → Al2(SO4)3(s) + 3H2(g)

(g) Ca(OH)2(s) + CO2(g) → CaCO3(s) + H2O(l)

(h) NH3(g) + HCl(g) → NH4Cl(s)

(i) Na2CO3(s) + H2O(l) → 2NaOH(aq) + CO2(g)

(j) 4Fe(s) + 3O2(g) → 2Fe2O3(s)

(j) Al2(SO4)3(aq) + 6H2(g) → 2Al(s) + 3SO3(g) + 6H2O(l)

(j) CaCO3(s) + H2O(l) → Ca(OH)2(aq) + CO2(g)

(k) P4(s) + 5O2(g) → P4O10(s)
