BRAINCAKECombustion
Alkenes burn in oxygen. In complete combustion (plenty of oxygen) all the carbon is converted into carbon dioxide and all the hydrogen into water:
C2H4 + 3O2 → 2CO2 + 2H2O
Because the formula is CnH2n, every alkene gives equal moles of CO2 and H2O, and needs 1.5n mol of O2 per mole:
