Question

15. Balance the following equations :
(a) CaCO3 (s) + HCl (aq) → CaCl, (aq) + H2O (1) + CO2 (g)
(b) Zn (s) + HCl (aq) → ZnCl2 (aq) + H2(g)
(c) MnO,(s) + HCl (aq) → MnCl(aq) + H2O (1) + Cl2 (g)
(d) Na CO2 (s) + H2SO4 (aq) → Na,SO4 (aq) + H2O (1) + CO2(g)
(e) Mg3N, (s) + H2O (1) ► Mg(OH)2 (s) + NH3(g)
(f) NH; (g) + O2(g) → N2 (g) + H2O (1)
