define combustion.state it type?
Answers
Answer:
Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen. When fuel and oxygen react it releases the heat and light energy. Heat and light energy then result in the flame. So, the formula for Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.
Explanation:
Answer:
Explanation:
Combustion refers to the process where a substance burns in the presence of Oxygen, giving off heat and light in the process.
Not all reactions can be said to be similar to this process. Even many people believe rusting of Iron is a similar process as rusting involves iron combining with oxygen giving off heat.
It is the spontaneity with which substances react with Oxygen which defines a reaction.
Hydrocarbon + Oxygen → Carbon Dioxide + Water + Heat Energy
Complete combustion: When the reaction takes place in the presence of abundant Oxygen, the substances combine with Oxygen to their maximum extent. Such reactions have heat and light as a visible by-product.
Incomplete combustion: These are defined as the reactions that occur in the absence of sufficient oxygen because of which substances are unable to burn completely. Such reactions leave Soot in the container due to this process along with the formation of Carbon monoxide which is an air pollutant.
Apart from classifications based on the availability of Oxygen, reactions are also categorized based on their spontaneity and rate of reaction. Reactions that proceed violently can either lead to fire or even explosion (which is also accompanied by loud noise). Formation of rust can also be categorized under slow combustion.
