what are the products to complete combustion of hydrocarbons?

Answers

Answered by 18p3490vie

Fuels are substances that react with oxygen to release useful energy. Most of the energy is released as heat, but light energy is also released.

In general, for complete combustion:

hydrocarbon + oxygen → carbon dioxide + water.

propane + oxygen → carbon dioxide + water.

When hydrocarbons are completely burned in the presence of adequate oxygen, water vapour and carbon dioxide are produced.

Hydrocarbons are compounds that have both hydrogen and carbon in them.
They are the main component of fossil fuels such as natural gas, petroleum, and coal.
Energy is extracted from fossil fuels by combusting them.
When a fuel burns in an abundance of air, it gets adequate oxygen to burn completely.
Complete combustion necessitates a large amount of air in order for the components in the fuel to react completely with oxygen.
Combustion with oxygen creates three products: carbon dioxide, water, and heat.
The energy required to break the bonds in hydrocarbon molecules is far less than the energy generated during the production of CO2 and H2O molecules' bonds.
As a result, considerable amounts of thermal energy are released during the process (heat). Therefore, it is an exothermic reaction.
This thermal energy can either be used directly or transformed into mechanical energy via a heat engine.
When the availability of oxygen is insufficient, incomplete combustion happens. Water is created, but instead of carbon dioxide, carbon monoxide and carbon are formed.
