2. What is combustion
Combustion is a chemical reaction that
occurs between a fuel and an oxidizing
agent that produces energy, usually in
the form of heat and light.
3. How it happened
Ina complete combustion reaction, a
compound reacts with an oxidizing
element, such as oxygen or fluorine, and
the products are compounds of each
element in the fuel with the oxidizing
element
4. A simple example can be seen in the
combustion of hydrogen and oxygen,
which is a commonly used reaction in
rocket engines
The result is water vapor.
5. For what it help
Thecarbon in fossil fuels return to
ecosystem, as humans burn fossil fuels to
release energy dust particles and gases
containing carbon are also release into
the environment. This is part of a cycle
called carbon cycle.
