Answer» (a) `2KBr(aq) + BaI_(2)(aq) to 2KI(aq) + BaBr_(2)(aq)` The reaction is known as double displacement reaction. (b) `ZnCO_(3)(s) to ZnO(s) + CO_(2)(g)` The reaction is known as decomposition reaction. (c) `H_(2)(g) + Cl_(2)(g) to 2HCl(g)` The reaction is known as combination reaction (d) `Mg(s) + 2HCl(aq) to MgCl_(2)(aq) + H_(2)(g)` The reaction is known as displacement reaction. |
