(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Copper (II) Chloride dihydrate is mixed with solid aluminum. Find the products and balance the equation.

2. Relevant equations

N/A

3. The attempt at a solution

The original equation that I got was:

CuCl2 ∙ 2H2O + Al --> AlCl3 + Cu + H2O

When I balanced it, I got:

3 CuCl2 ∙ 2H2O + 2 Al --> 2 AlCl3 + 3 Cu + 2 H2O

but I'm unsure about that. I am just wondering if the H2O at the end of the equation should have a coefficient of 6 because 3 [CuCl2 ∙ 2 H2O] were needed. So then the equation would be:

3 CuCl2 ∙ 2H2O + 2 Al --> 2 AlCl3 + 3 Cu + 6 H2O instead?

I do not know which one is correct. Please help me!
