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

2.5 moles of H2 will be produced by
`(5)/(3)` moles of Al

Step-by-step 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
`(2)/(3)` moles of Al

2.5 moles of H2 will be produced by
`(2)/(3) * 2.5 = (5)/(3)` moles of Al
