CHEMISTRY 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) October 15, 2019 avatar Noor Savani Share Save VIDEO EXPLANATION ANSWER (a) Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s) 2KBr (aq)
+BaI 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) 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 (d) Magnesium(s) + Hydrochloric acid(aq) → Magnesium chloride(aq) + Hydrogen(g) Mg (s)
+2HCl (aq)
→MgCl 2
(aq)
+H 2
(g)
In this reaction, more reactive Mg is replacing less reactive H. Hence, it is displacement reaction |
