Incomplete combustion. Incomplete combustion means burning in a lack of air (not enough oxygen).If there is not enough oxygen available for all the carbon to turn into carbon dioxide (see complete combustion), then some or all of the carbon turns to carbon monoxide.This happens with 2 H 2 C 2 (g) + 5 O 2 (g) --> 4 CO 2 (g) + 2 H 2 O (g) Because of the visual display, this demonstration is sometimes referred to as "fire rocks" ( see demonstration 5.20k ). Air is 1/5th O … The acetylene in this lab will be collected in a test tube and burned. If you have a higher ratio than that, combustion will be incomplete. For complete combustion, the equation is: 2 C2H2 + 5 O2 → 4 CO2 + 2 H2O. A combustion reaction occurs when a compound merges with oxygen to release heat in an exothermic reaction. C2H2, ethyne, is a hydrocarbon. So the balanced equation for the incomplete combustion is: 2C 2 H 2 + 3O 2 → 4CO + 2H 2 O However, combustion tends to be less complete as the number of carbon atoms in the molecules rises.
