(i) ZnCO3(s) - ZnO(s) + CO2(g)
(ii) Pb(s) + CuCl2 (aq) - PbCl2(aq) + Cu(s)
(iii) NaBr(aq) + AgNO3(aq) - AgBr(s) + NaNO3(aq)
(iv) H2(s) + Cl2(g) → 2HCI(8)
(v) Fe2O3(g) + 2AI - AI2O3 + 2Fe(s)
(vi) 3H2(g) + N2(g) → 2NH3(g)​

Answer 1

Answer:

(i) ZnCO3(s) - ZnO(s) + CO2(g) =Decomposition Reaction

(ii) Pb(s) + CuCl2 (aq) - PbCl2(aq) + Cu(s) =Displacement Reaction

(iii) NaBr(aq) + AgNO3(aq) - AgBr(s) + NaNO3(aq)=Double Displacement Reaction

(iv) (iv) H2(s) + Cl2(g) → 2HCI(8) =Combination Reaction

(v) Fe2O3(g) + 2AI - AI2O3 + 2Fe(s) =Redox Reaction

(vi) 3H2(g) + N2(g) → 2NH3(g)​=Combination Reaction
