Question

9) Chlorine is prepared in the laboratory by treating M,O2 with
aqueous hydrochloric acid according to reaction
4 HCl(aq) + M,O2 +2H200 + M Cl2 aq) + Clzig)
How many grams of HCI react with 5 g of M,O2?
[ Atomic Mass : CI = 35.5 and Mn = 55 u ] for class 11 science for 3 marks ​

Answer 1

Answer:

According to the given equation:

MnO

2

+4HCl→MnCl

2

+Cl

2

+2H

2

O

1 mole of MnO

2

reacts with 4 mole of HCl

or 87 g MnO

2

reacts with 146 g HCl

∴ 5 g MnO

2

Will react with

87

146

×5gHCl=8.39HCl
