When a compound containing c, h, and o is completely combusted in air, what reactant besides the hydrocarbon is involved in the reaction? express your answer as a chemical formula. identify the phase in your answer?

A special type of combination is combustion. One of the key reactants in a combustion reaction must always involve an oxygen. This is the defining characteristic of combustion. When a combustible matter is burned, it reacts with the oxygen in air in the presence of heat. Moreover, one of its end products must be water. Let's take glucose as our example of a hydrocarbon.

C6H12O6(s) + 6O2(g)  > 6CO2 (g) + H2O(g)

Therefore, when a solid glucose interacts with oxygen gas, it yields carbon dioxide and water vapor.

The answer is !
