I think it will be B. Hope it helps :)
Answer: 1 mol of
will be produced from this reaction.
Explanation: Reaction follows,

As seen from the balanced chemical equation above, we get
For every 3 moles of Aluminium and 3 moles of
, 1 mole of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 1 mole of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 3 moles of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 6 moles of
is formed.
Mg (s) + HCl (aq) → MgCl₂(s) + H₂(g)
Looking at the equation :
We have 1 Mg at the left hand side and 1 Mg as well on the right hand side.
So that is balanced.
We have 1 H at the left hand side and 2 H on the right hand side.
So that is not balanced. Same for Chlorine. Cl.
We add 2 to the HCl on the left hand side and that balances it.
Mg(s) + 2HCl(aq) → MgCl₂(s) + H₂(g)
