If 1.6 g of `SO_(2)` and `1.5xx10^(22)` molecules of `H_(2)S` are mixed and allowed to remain in contact in a closed vessel until the reaction
`2H_(2)S+SO_(2)rarr 3S+2H_(2)O`
proceeds to completion. Which of the following statement is true?

Options

A. Only 'S' and `'H_(2)O'` remain in the reaction vessel
B. `'H_(2)S'` will remain in excess
C. Nither `H_(2)S` nor `SO_(2)` will remain
D. SO_(2) will remain in excess

Answer

D

Explanation

`{:(C_(x)H_(y)+(x+(y)/(4))O_(2)rarrxCO_(2)+(y)/(2)H_(2)O),("10 ml 40 ml 50 ml"),("1 ml 4 ml 5ml"):}`
`therefore x=4`
`(y)/(2)=5 rArr y=10`
`"hydrocarbon is "C_(4)H_(10)`
