Every combustion reaction we deal with produces gas with oxygen in the product, so O2 (oxygen gas) must be a reactant.
For example, methane reacts with Oxygen in this way:
CH4(l) + O2(g) -> C02(g)+2H2(g)
Note O2 in gaseous form as a reactant.
Oxygen is always a reactant in a combustion reaction.
A combustion reaction generally includes a hydrocarbon (some type of fuel) and oxygen
Combustion is burning of of any compound in presence of oxygen. So the reactants will be oxygen and the compound under consideration.
This element is oxygen.

a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
The type of reaction that always has an element and a compound as reactants is a single displacement reaction, or a substitution reaction. These are of the form A + BC ---> AC + B.

Combustion reactions always have O2 as a reactant. The other reactant is the thing being burned. If the thing being burned is a hydrocarbon, the products will be water and carbon dioxide.
Assuming you have given a complete equation, no. It requires oxygen as a reactant and will always have CO2 and H2O as products. Plus, combustion reactions typically involve carbon based elements as reactants.

Limiting reactant is the one that limits the rate of the reaction. It is always supplied in adequate amount so that there is enough for the reaction to carry out to obtain the desired products. under ideal cases, When the reaction reaches completion there will be no limiting reactant.
