Question10 of 10Iron reacts with hydrochloric acid to produce iron(II) chloride and hydrogen gas.Fe + 2 HCl --> FeCl2 + H2How many moles of HCl will react with 4.6 moles of Fe?2.32.84.66.99.2

Answer 1

Answer: The number of moles of HCl that will react with given amount of Fe is 9.2 moles.

Explanation:

We are given:

Moles of iron = 4.6 moles

For the given chemical reaction:

$Fe+2HCl\rightarrow FeCl_2+H_2$

By Stoichiometry of the reaction:

1 mole of iron reacts with 2 moles of hydrochloric acid.

So, 4.6 moles of iron will react with = $\frac{2}{1}\times 4.6=9.2mol$ of hydrochloric acid.

Hence, the number of moles of HCl that will react with given amount of Fe is 9.2 moles.
