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 + Hydrochloric →Magnesium chloride (aq) + Hydrogen (g)
(a) Double displacement reaction (also known as precipitation reaction):
2KBr (aq) + Bal2 (aq) → 2KI (q) + BaBr2 (s)
(b) Decomposition reaction:
ZnC03 (s) → ZnO (s) + C02 (g)
(c) Combination reaction:
H2 (g) + Cl2 (g) → 2HC1 (g)
(d) Displacement reaction:
Mg (s) + 2HCL (aq) → MgC12 (aq) + H2 (g)
