Hydrogen chloride gas and oxygen react to form water vapor and chlorine gas. What volume of water would be produced by this reac
AlladinOne [14]

Answer: 3.4 L

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given Volume}}{\text {Molar Volume}}=\frac{6.5L}{22.4L}=0.29moles

The balanced chemical equation for reaction of Hydrogen chloride gas with oxygen to form water vapor and chlorine gas.

4HCl(g)+O_2(g)\rightarrow 2H_2O(g)+2Cl_2(g)

According to stoichiometry :

4 moles of HCl produce = 2 moles of H_2O

Thus 0.29 moles of HCl will produce =\frac{2}{4}\times 0.29=0.15moles  of H_2O

Volume of H_2O=moles\times {\text {Molar Volume}}=0.15moles\times 22.4L/mol=3.4L

Thus 3.4 L of of water would be produced by this reaction if 6.5 L of hydrogen chloride were consumed
