Question:-
Consider the following:
Carbon
Carbon-monoxide
Hydrogen, and
Sulphur
What is the amount of oxygen (in kg) required for complete combustion of each one of the above respectively?
Option (A)
1, 8, 8/3, 4/7
Option (B)
4/7, 1, 8, 8/3
Option(C)
8/3, 4/7, 8, 1
Option(D)
8, 1, 4/7, 8/3
Correct Option:
(C)
Question Solution:
C + O2 ® CO2
CO + (1/2)O2 ® CO2
H2 + (1/2) O2 ® H2O
S + O2 ® SO2
Amount of oxygen required for carbon = 32/12 = 8/3
Amount of oxygen required for CO = 16/28 = 4/7
Amount of oxygen required for H2 = 16/2 = 8
Amount of oxygen required for S = 32/32 = 1
