Answer:
2Al + 6HCl —> 3H₂ + 2AlCl₃
Explanation:
From the question given above:
Al + HCl —> H₂ + AlCl₃
The above equation can be balance as illustrated below:
Al + HCl —> H₂ + AlCl₃
We have 1 atom of Cl on the left side and 3 atoms on the right side. It can be balance by putting 6 in front of HCl and 2 in front of AlCl₃ as shown below:
Al + 6HCl —> H₂ + 2AlCl₃
We have 6 atoms of H on the left side and 2 atoms on the right side. It can be balance by 3 in front of H₂ as shown below:
Al + 6HCl —> 3H₂ + 2AlCl₃
We have 1 atom of Al on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of Al as shown below:
2Al + 6HCl —> 3H₂ + 2AlCl₃
Thus, the equation is balanced.
