Answer :
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:
[tex]4HCl+O_2\rightarrow 2H_2O+2Cl_2[/tex]
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 [tex]\frac{9.5}{4}\times 2=4.75L[/tex] volume of water
Therefore, the volume of water produced by this reaction would be, 4.75 liters.
