Answer 1

The reaction is given by the equation:

\[ \text{H}_2 + \text{Cl}_2 \rightarrow 2\text{HCl} \]

From the stoichiometry of the reaction, 1 mole of \( \text{H}_2 \) produces 2 moles of \( \text{HCl} \).

If we start with 10 moles of \( \text{H}_2 \):

\[
\text{Moles of HCl produced} = 10 \text{ moles H}_2 \times \frac{2 \text{ moles HCl}}{1 \text{ mole H}_2} = 20 \text{ moles HCl}
\]

So, the number of moles of HCl produced is **20 moles**.
