Question

Write the suitable balanced chemical equaiton of a) Displacement reaction. b) Combinaiton reaction.

Answer 1

Answer:

Mg+2HCl-->MgCl2+H2 -- displacement reaction

H2+Cl2-->2HCl-- combination reaction

Answer 2

Answer:

Explanation:

Combination Reaction: If in a Chemical equation, two or more reactants combine to form a single product then it is known as combination reaction.

                             CaO(s) + H2O(l) ---- Ca(OH)2 (aq)

Decomposition reaction: If in a chemical reaction a single substance decomposes to form two or more substances then it is known as decomposition reaction.

                    CaCO3 (s) + CuSO4 (aq) --- ZnSO4 (aq) + Cu (s)
