Question

Volume of HCl gas formed when 2 litres hydrogen reacts completely with 2 dm^3 of chlorine gas is--- *​

Answer 1

Answer:

So, 2 litres of 2 dm³ volume. Now, At STP , 22.4 dm³ reacts with 22.4 dm³ to produce 44.8 dm³ of HCl.

Answer 2

Solution:

HCl gas is formed when Hydrogen gas reacts with chlorine gas.

$H_{2} + Cl_{2} \rightarrow 2HCl$

From the above reaction, it is clear that 1 mole of Hydrogen reacts with 1 mole of Chlorine to form 2 moles of HCl.

Molar ratio of Hydrogen gas : Chlorine gas : HCl gas = 1 : 1 : 2

At STP, 1 mole = 22.4 L

2 Litres of Hydrogen reacts with 2 Litres of Chlorine gas to form 4 litres of HCl.
