is to burn. In every complete combustion equation a hydrocarbon(CxHy)
reacts with oxygen (O2)
to produce water (H2O)
and carbon dioxide (CO2).
Combustion reactions that the pattern of : CxHy +
O2(g) --> H2O(g)
25O2 --> 18H2O
reacts with oxygen gas to produce water and carbon
let’s go step by step.
Write the reaction for the complete combustion of propane (C3H8).
|1. Write the formula for the given reactant.
|2. Add oxygen, O2, as a reactant. Don't forget that oxygen is a diatomic molecule.
||C3H8 + O2 -->
|3. Your products are ALWAYS H2O and CO2 in a complete combustion. Write H2O and CO2 on the products side.
||C3H8 + O2 --> H2O + CO2
|4. Balance the equation
||C3H8 + 5O2 --> 4H2O + 3CO2
