Question

10 mol of Zn react with 10 mol of HCl. Calculate the number of mola of H, produced (a) 5 mol (b) 10 mol (c) 20 mol (d) 2.5 mol​

Answer 1

Good morning everyone

ANSWER:

A) 5 mol

EXPLANATION:

The chemical equation of reaction of zinc with hydrochloric acid (HCl)

Zn+2HCl => ZnCl2+H2

Here 2 moles of HCl reacts with 1 mole of zinc

Hence we should find for 10 moles of HCl

10/2 = 5

So the answer is 5 moles. I hope it works. Thank you have a nice day.
