Question

2. Copper chloride and aluminum react to produce aluminum chloride and copper. Which of the following is the correctly balanced chemical equation for this reaction?

a. 2Al(s)+ 3CuCl2(aq) --> 2Cu(s) + 3AlCl3(aq)



b. 3Al(s) + 3CuCl2(aq) --> 3Cu(s) + 2AlCl2(aq)



c. 2Al(s) + 3CuCl2(aq) --> 3Cu(s) + 2AlCl3(aq)



d. 3Al(s) + 2CuCl2(aq) --> 3Cu(s) + 2AlCl3(aq)

Answer 1

Answer:

Option C is correct

2Al(s) + 3CuCl2(aq) --> 3Cu(s) + 2AlCl3(aq)

Answer 2

Answer:

$2Al+3CuCl_{2} --- > 2AlCl_{3} +3Cu$ , Therefore C is the correct answer

Explanation:

Aluminium reacts with copper chloride to generate copper metal and aluminium chloride. Because aluminium is more reactive than copper, it displaces copper from a copper chloride solution according to metal reactivity. The chemical equation is as follows:

$Al(s) + CuCl_{2} (aq) - > AlCl_{3} (aq) + Cu(s)$

A chemical equation represents a chemical process in the form of substances. A balanced chemical equation is one in which the number of atoms in all the molecules is equal on both sides of the equation. A chemical equation's balancing is governed by the Law of Conservation of Mass.

The following chemical equation can be balanced.

$2Al+3CuCl_{2} --- > 2AlCl_{3} +3Cu$
