Question

Aluminum metal reacts with copper(II) chloride to produce aluminum chloride and copper metal. I need a balanced chemical equation

Answer 1

Answer:

2Al+ 3CuCl2= 2AlCl3 +3Cu

Answer 2

Answer:

The balanced chemical equation is:

$2 Al +3CuCl_{2}$ → $2AlCl_{3} +3Cu$

Explanation:

The chemical equation for the given reaction can be written as:

$Al+CuCl_{2}$ → $AlCl_{3} +Cu$

First, we have to compare coefficients on both sides of the equation.

We have $2Cl$ on LHS and $3Cl$ on RHS. So we have to multiply $CuCl_{2}$ with 3 and $AlCl_{3}$ with 2. Then the equation can be written as:

$Al+3CuCl_{2}$ → $2AlCl_{3}$ $+Cu$

Now we have $1Al$ on LHS and $2Al$ on RHS. Also, we have $3Cu$ on LHS and $1Cu$ on RHS.

So we have to multiply $Al$ with 2 on LHS and $Cu$ with 3 on RHS. Now the balanced equation can be written as:

$2Al+3CuCl_{2}$ → $2AlCl_{3} +3Cu$
