when does combustion occour

it occours whenever something reacts with oxygen gas (02)

complete combustions formula is

fuel + oxygen = carbon dioxide + water

incomplete combustions formula is

fuel + oxygen = carbon mondioxide + water

the product of fuel + oxygen (complete)

carbon dioxide + water

the product of fuel + oxygen (incomplete)

carbon mondioxide + water
