1.	Write the balanced chemical equation for the following and identify the type of reaction in each case. (a) Potassium bromide(aq) + Barium iodide(aq) rarr Potassium iodide(aq) + Barium bromide(s) (b) Zinc carbonate(s) rarr Zinc oxide(s) + Carbon dioxide(g) (d) Magnesium(s) + Hydrochloric acid(aq) rarr Magnesium chloride(aq) + Hydrogen(g)
Answer» Solution :(a) `2KBr(AQ)+BaI_(2)(aq)rarr2KI(aq)+BaBr_(2)(s)`, Double displacement reaction (B) `ZnCO_(3)(s)rarrZnO(s)+CO_(2)(g)`, Decomposition reaction (c ) `H_(2)(g)+Cl_(2)(g)rarr2HCl(g)`, Combination reaction (d) `Mg(s)+2HCl(aq)rarrMgCl_(2)(aq)+H_(2)(g)`, Displacement reaction
