1.	13. If 6 litres of hydrogen and 4 litreand exploded and if water is added to the gases formed,(2015)find the volume of the residual gas.
Answer» The required reaction is, H2 + Cl2 ==>2HCl Here 6 litres of H2 reacts with 4 litres of chlorine. But by Gay Lussacs law, 1 volume of hydrogen will react with 1 volume of chlorine. Here the taken volume is 4 litres. As HCl is highly soluble in water.It will soon dissolve[as water is added].And H2 gas will be left. So the residual gas volume is = 6 litres - 4 litres. = 2 litres. thnxx

13. If 6 litres of hydrogen and 4 litreand exploded and if water is added to the gases formed,(2015)find the volume of the residual gas.

Answer»

The required reaction is,

H2 + Cl2 ==>2HCl

Here 6 litres of H2 reacts with 4 litres of chlorine.

But by Gay Lussacs law,

1 volume of hydrogen will react with 1 volume of chlorine.

Here the taken volume is 4 litres.

As HCl is highly soluble in water.It will soon dissolve[as water is added].And H2 gas will be left.

So the residual gas volume is = 6 litres - 4 litres.

= 2 litres.
