(a) 2KBr(aq) + BaI2(aq) ➝ 2KI(aq) + BaBr2(aq)
The reaction is known as double dis-placement reaction.
(b) ZnCO3(s) ➝ ZnO(s) + CO2(g)
The reaction is known as decomposition reaction.
(c) H2(g) + Cl2(g) ➝ 2HCl (g)
The reaction is known as combination reaction.
(d) Mg(s) + 2HCl(aq) ➝ MgCl2(aq) + H2(g)
The reaction is known as displacement reaction.
