2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
Here's a breakdown of the equation:
* Al (s) represents aluminum metal in its solid state.
* HCl (aq) represents hydrochloric acid in its aqueous (dissolved in water) state.
* AlCl₃ (aq) represents aluminum chloride, which is formed as a soluble salt in the reaction.
* H₂ (g) represents hydrogen gas, which is produced as a byproduct of the reaction and escapes as a gas.
This is a single displacement reaction where aluminum displaces hydrogen from hydrochloric acid.
