Write the balanced chemical equation for the following and identify the type of reaction in each case.
(a) Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)
(b) Zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)
(c) Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)
(d) Magnesium(s) + Hydrochloric acid(aq) → Magnesium chloride(aq) + Hydrogen(g
(a) 2KBr + BaI2 → 2KI + BaBr2
Type of reaction: Double displacement reaction. Because the cation K+ and Ba2+ have exchanged their anions Br- and SO42- .
(b) ZnCO3 → ZnO + CO2
Type of reaction: Decomposition reaction. Because in this reaction single reactant break down into two product
(c) H2 + Cl2 → 2HCl
Type of reaction: Combination. Because in this reaction two reactant combine into single product.
(d) Mg + 2HCl → MgCl2 + H2
Type of reaction : disclacement reaction because H in HCl has been displaced by Mg.
