Agata [3.3K]

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

<u>Explanation:</u>

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.
