10cm3 of CO is mixed and sparked with 100cm3 of air containing 21% O2. If all the volumes measured at S.T.P. the volume of resulting gases would be?
90cm3
100cm3
105cm3
110cm3
115cm3
Correct answer is C
2CO(g) + O2(g) ---> 2CO2(g)
2vol 1vol 2vol
Volume in cm3 Before sparking: 10 // 21
Volume in cm3 On sparking 10 // 5 // 10
Volume in cm3 After sparking: 0// 16 // 10
Total volume of resulting gas = Volume of [excess oxygen + CO2 produced + unreactive components]
= 16 + 10 + 79 → 105cm3
