Question

Write the balanced chemical equation for the following and identify the type of reaction in
each case.
(i) Potassium bromide(aq) + barium iodide(aq) potassium iodide (aq) + bromide(s)
(ii) Zinc carbonate (s) zinc oxide (s) + carbon dioxide (g)
(iii) Hydrogen (g) + chlorine (g) hydrogen chloride (g)
(iv) Magnesium (s) + hydrochloride acid (aq) magnesium chloride(aq) + hydrogen(g)

Answer 1

Answer:

(iii) H2 + cl2 ---- 2Hcl

(iv) Mg + HCl ----- Mgcl2 + h2

Explanation:

hope it helps

Answer 2

(I) 2KBr (aq) + BaI2 (aq) ---> 2KI (aq) + 2Br (s)

This is double-displacement Reaction

(ii) ZnCO3 (s) --------> ZnO (s) + CO2 (g)

This is Decomposition Reaction

(iii) H2 (g) + Cl2 (g) -------> 2HCl (g)

This is Combination Reaction

(iv) Mg (s) + 2HCl (aq) -----> MgCl2 (aq) + H2 (g)

This is Displacement Reaction.
