Answer:
2Al (s) + 6HCl (aq) → 2 AlCl3 (aq) + 3H2 (g)↑
Explanation:
- We can put an up arrow to H2 cause as it is a gas, it can be released to the atmosphere.
- Aluminum as metal must be solid.
- As we have two solutions, both are aqueous phase.
- The stoichiometry must match on both sides of the reaction to have the same amount of elements of each compound.}
