The chemical equation for this reaction is Al + HNO3 → Al(NO3)3 + H2.
This reaction is a single replacement reaction, also known as a displacement reaction.
To balance the equation, you must make sure that there is the same number of atoms for each element on both sides of the equation. In this case, you would need to add a coefficient of 2 in front of HNO3 to balance the equation, resulting in 2Al + 2HNO3 → 2Al(NO3)3 + H2.
The products of this reaction are aluminum nitrate (Al(NO3)3) and hydrogen gas (H2).
The reaction between aluminum and nitric acid is exothermic, meaning it releases heat energy.
