Answer :
The following is the balance chemical equation:
3 H2 + 2 AlCl3 result from 2 Al + 6 HCl.
By calculating the created H2 in moles,
Using the equation,
H2 is produced when 3.0 moles of HCl are added.
So,
X moles of H2 will be produced by 3.40 moles of HCl.
By figuring out X,
X = (3,40 mol x 3,0 mol x 3,0 mol) mol
X = 3.4 moles of hydrogen
Aluminium interacts with weak hydrochloric acid at room temperature. The dissolution of the metal in hydrochloric acid results in the production of aluminum chloride and colorless hydrogen gas. Because the finished products do not interact, this reaction cannot be stopped.
Aluminum may initially seem as though it won't react when placed in an acid. This is due to the coating of aluminum oxide that develops on the surface of the metal as a result of an earlier interaction with the air and serves as a barrier of protection.
