Question

(54)
If 1.6 g of SO2 and 1.5 x 10raise to the power22 molecules of H2S
are mixed and allowed to remain in contact in a
closed vessel until the reaction
2H2S + SO2gives 3s + 2H2O,
proceeds to completion. Which of the following
statement is true ?
(1) Only 'S' and 'H2O' remain in the reaction vessel.
(2) 'H2 S' will remain in excess
(3) 'SO2 will remain in excess
(4) None​

Answer 1

Answer:

Explanation:

2H2S (g) + SO2 (g) --------> 2H2O (l) + 3S (s)

According to the reaction equation ,

 

2 moles of H2S combines with 1 mole of SO2 to give three moles of sulphur.

Therefore, the ratio of moles of H2S , SO2 and S is 2:1:3

Dividing by 4 , we get

H2S : SO2 : S as 0.5 : 0.25 : 0.75

Answer 2

hey dear your answer is here

If 1.6 g of SO2 and 1.5 x 10raise to the power22 molecules of H2S

are mixed and allowed to remain in contact in a

closed vessel until the reaction

2H2S + SO2gives 3s + 2H2O,

proceeds to completion. Which of the following

statement is true ?

please mark me as brainliest ✌️✌️

(a) is correct answer

1) Only 'S' and 'H2O' remain in the reaction vessel.
