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. \(2KBr_{(aq)}+Bal_{2(aq)} \rightarrow 2Kl_{(aq)}+BaBr_{2(aq)}\) ; Double displacement reaction
b. \(ZnCO_{3(s)} \rightarrow ZnO_{(s)} + CO_{2(g)}\) ; Decomposition reaction
c. \(H_{2(g)}+Cl_{2(g)} \rightarrow 2HCl_{(g)}\) ; Combination reaction
d. \(Mg_{(s)}+2HCl_{(aq)} \rightarrow MgCl_{2(aq)}+ H_{2(g)}\) ; Single displacement reaction
