Question

Combine each side and then balance the whole equation. Al+HCl=AlCl3+H^+

Answer 1

`2Al + 6 HCl ---> 2AlCl_3 + 3 H_2`

Step-by-step explanation:

The valency of aluminium is +3 while the valency of chlorine is -1

we will first write the half reactions

Half oxidation reaction

`Al -----> Al^(3+) + 3^(e-)\\2H^+ 2e^- ----> H_2\\Cl + e^- -----> Cl^-`

Now will write the complete equation-

`Al + HCl -----> AlCl_3 + H_2`

The balanced equation would be

`2Al + 6 HCl ---> 2AlCl_3 + 3 H_2`
