Question

2Al +6HCl → 2AlCl3 + 3H2 then solve the problem below. Find the number of moles of Al used to produce 2.5 moles of H2

Answer 1

Answer:

2.5 moles of H2 will be produced by $\frac{5}{3}$ moles of Al

Explanation:

The given equation is  a balanced equation

2Al +6HCl → 2AlCl3 + 3H2

As per this reaction, 2 moles of Al are used to produce 3 moles of H2

1 mole of H2 will be produced by $\frac{2}{3}$ moles of Al

2.5 moles of H2 will be produced by $\frac{2}{3} * 2.5 = \frac{5}{3}$ moles of Al
