Question

give any two example of combustion reaction ad also give definition of combustion

Answer 1

Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. In the more general sense, combustion involves areaction between any combustible material and an oxidizer to form an oxidized product.

combustion of methane
CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)burning of naphthalene
C10H8 + 12 O2 → 10 CO2 + 4 H2Ocombustion of ethane
2 C2H6 + 7 O2 → 4 CO2 + 6 H2Ocombustion of butane (commonly found in lighters)
2C4H10(g) +13O2(g) → 8CO2(g) +10H2O(g)combustion of methanol (also known as wood alcohol)
2CH3OH(g) + 3O2(g) → 2CO2(g) + 4H2O(g)
