Question

Consider this reaction:

Answer 1

Answer:

$\large \boxed{\text{C. 112 L}}$

Explanation:

We can use Avogadro's Law: Equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules.  

To say it another say, gases react in the same volume ratios as their coefficients in the balanced equation.

  H₂  +    Cl₂  ⟶ 2HCl

1 mol + 1 mol ⟶ 2 mol

  1 L  +   1 L    ⟶   2 L

Thus,

$\text{Volume of HCl} = \text{56 L Cl}_{2} \times \dfrac{\text{2 L HCl}}{\text{1 L Cl}_{2}} = \textbf{112 L HCl}\\\\\text{The volume of HCl is \large \boxed{\textbf{112 L}} }$
