(a) Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)

2KBr (aq)+BacI 2(aq)

→2KI (aq) +BaBr 2(s)

In this reaction, both the reactants exchanges ions to for two new products, hence, it is a double displacement reaction

(b) zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)

ZnCO 3(s)

→ZnO (s) +CO 2(g)

In this reaction, a single substance yields two different product. hence, it is a decomposition reaction

(c) Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)

H 2(g) +Cl 2(g)

→2HCl (g)

In this reaction, two different reactants react with each other to form a single product. Hence, it is called a combination reaction
