Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which equations represent the incomplete combustion of methane?I. CH4(g) + 2 O2(g)

A	I and II only
B	I and III only
C	II and III only
D	I, II and III

Explanation:

Detailed explanation-1: -4CH4(g)+7O2(g)→2CO(g)+2CO2(g) + 8H2O(l)

Detailed explanation-2: -Therefore, CH4+O2→C(s)+2H2O is an incomplete combustion.

Detailed explanation-3: -Balanced equation is: CH4+2O2→CO2+2H2O.

Detailed explanation-4: -The equation for incomplete combustion of propane is: 2 C3H8 + 9 O2 → 4 CO2 + 2 CO + 8 H2O + Heat. If not enough oxygen is present for complete combustion, incomplete combustion occurs. The result of incomplete combustion is, once again, water vapour, carbon dioxide and heat. But it also produces carbon monoxide.
