HOPE IT HELPS YOU

IF MY ANSWER IS RIGHT PLEASE MARK ME IT AS BRAINLIST

Answer 2

Answer:

(1) 40 mL

Explanation:

As no.of moles = Volume at STP/Volume of compound

​n H2 = 20/22.4l

​n Cl2 = 20/22.4l

​H 2+Cl 2 ⇌2HCl

1+1⇌ 2

1 mole of H2 and 1 mole of Cl2 gives 2 mole of HCl.

So,20ml of h2 and 20ml of cl2 will give 40ml of hcl at stp.

So, the final answer is Volume of HCL at STP is 40ml.
