Question10 of 10Iron reacts with hydrochloric acid to produce iron(II) chloride and hydrogen gas.Fe + 2 HCl --&gt; FeCl2 + H2How
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.

the empirical formula of a compound is NO2. it's molecular mass is 92g/mol. What is its molecular formula?
lesantik [10]
The molecular formula:
N_x(O_2)_x

M_{N_x(O_2)_x}=x \times M_N + x \times 2 \times M_O \\ \\&#10;m_N=14 \ \frac{g}{mol} \\&#10;m_O=16 \ \frac{g}{mol} \\ M_{N_x(O_2)_x}=92 \ \frac{g}{mol} \\ \\&#10;92=x \times 14+x \times 2 \times 16 \\&#10;92=14x+32x \\&#10;92=46x \\&#10;\frac{92}{46}=x \\&#10;x=2 \\ \\&#10;N_2(O_2)_2 \Rightarrow N_2O_4

The molecular formula is N₂O₄.
