CuCl2 (aq) + Zn (s) →Cu (s) + ZnCl2 (aq) is an example of which type of reaction?

A) decomposition

B) redox

C) double-displacement

D) acid-base

The answer to your question is letter B.

Explanation:

Decomposition reaction: is a kind of chemical reaction where one reactant yields 2 or more products.

Redox: is a kind of chemical reaction where there is a change in the oxidation numbers of some reactants and products.

Double-displacement: is a kind of chemical reaction where two reactants interchange cations and anions.

Acid-base: in this chemical reaction an acid and a base react to yield a salt and water.

According to this information, the reaction given is:

a) it is not a decomposition reaction because it has two reactants.

b) Redox because Zn and Cu changed their oxidation numbers.

c) It is not a double-displacement reaction because "Zn" does not have an anion.

d) It is not an acid-base reaction because the products are not water and salt.
