Question

hydrogen chloride gas and oxygen react to form water vapor and chlorine gas. What volume of water would be produced by this reaction if 9.5 L of hydrogen chloride were consumed?

Answer 1

Answer : The volume of water produced by this reaction would be, 4.75 liters.

Explanation : Given,

Volume of HCl gas = 9.5 L

The balanced chemical reaction will be:

`4HCl+O_2\rightarrow 2H_2O+2Cl_2`

As we know that at STP, 1 mole of gas occupy 22.4 L volume of gas.

By the stoichiometry we can say that:

As, 4 liter volume of HCl gas react to give 2 liter volume of water

So, 9.5 liter volume of HCl gas react to give
`(9.5)/(4)* 2=4.75L` volume of water

Therefore, the volume of water produced by this reaction would be, 4.75 liters.
