Write a balanced chemical equation for the following and identify the type of reaction of each case. KBr + BaI2 → KI + BaBr2 ZnCO3 → ZnO + CO2 H2 + Cl → HCl Mg + HCl → MgCl2 + H2

2KBr + BaI₂ → 2KI + BaBr₂ (Double Displacement Reaction)

ZnCO₃ → ZnO + CO₂ (Decomposition Reaction)

H₂ + Cl → 2HCl (Combination Reaction)

Mg + 2HCl → MgCl₂ + H₂ (Displacement Reaction)
