What is the combustion of hydrocarbons?
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon.
What is combustion BBC Bitesize?
Combustion is another name for burning. In a combustion reaction, fuel is burned and reacts with oxygen to release energy.
How does the combustion of hydrocarbons contribute to pollution?
The combustion of hydrocarbon fuels releases carbon dioxide (CO2), as well as other greenhouse gases that contribute to atmospheric pollution and climate change. Unlike fossil fuel impurities that result in byproduct emissions, CO2 is an unavoidable result of hydrocarbon combustion.
What does complete combustion of hydrocarbons produce?
Complete combustion of hydrocarbons (without impurities) in the presence of enough oxygen produces water vapor and carbon dioxide.
Why the combustion of all hydrocarbons is exothermic?
Common combustion reactions break the bonds of hydrocarbon molecules, and the resulting water and carbon dioxide bonds always release more energy than was used to break the original hydrocarbon bonds. That’s why burning materials mainly made up of hydrocarbons produces energy and is exothermic.
Do all hydrocarbons undergo combustion?
All hydrocarbons (including alkanes, alkenes and cycloalkanes) can undergo combustion reactions with oxygen to give the same two products. Hydrocarbon fuels burn when they react with oxygen in the air.
How do you find the combustion reaction?
Balancing combustion reactions is easy. First, balance the carbon and hydrogen atoms on both sides of the equation. Then, balance the oxygen atoms. You balance oxygen after carbon and hydrogen because it is always standing alone as O2, and it is easier to balance than H and C….Step 3.

What is combustion GCSE chemistry?
Combustion is the name given to reactions where a fuel combines with oxygen. There are many examples of combustion. Natural gas (methane) burns to form carbon dioxide and water. This is typical of all hydrocarbons (provided that they have a good supply of oxygen).
What is complete combustion of fuels?
Complete combustion Fuels are substances that react with oxygen to release useful energy (exothermic). Most of the energy is released as heat, but light energy is also released. About 21 per cent of air is oxygen. When a fuel burns in plenty of air, it receives enough oxygen for complete combustion.
How is complete combustion of a hydrocarbon different from incomplete combustion?
Complete combustion of hydrocarbons will result in the production of carbon dioxide and water, while an incomplete combustion of hydrocarbons will result in the production of carbon monoxide and water.
How does complete combustion affect the environment?
Environmental aspects of combustion There are various impacts of combustion on the environment, these impacts can be caused by; Gas leaks, oil spillage, noise and air pollution. Incomplete combustion of hydrocarbons also results in carbon monoxide pollution.
