Question
On repeated sparking 10 mL of a mixture of carbon monoxide and nitrogen required 7 mL of oxygen for combustion. What was the volume of nitrogen ? (All volumes are measured under identical conditions).
Options
A.7/2 mL
B.4 mL
C.7 mL
D.17/2 mL
Solution
CO = x mL, N2 = (10 - x) mL
CO +
O2 → CO2,
N2 + O2 → 2NO
O2 required =
mL, O2 required = (10 - x) mL
+ (10 - x) = 7, x = 6 mL
N2 = 10 - 6 = 4 mL
CO +
O2 → CO2,N2 + O2 → 2NO
O2 required =
mL, O2 required = (10 - x) mL+ (10 - x) = 7, x = 6 mLN2 = 10 - 6 = 4 mL
