Question

combustion reaction are Redox reaction in nature? define combustion reaction also?​

Answer 1

Oxidation, reduction, and redox reactions can all be defined in two ways.

The simpler definitions refer to reactions involving some form of oxygen. As an example, pure iron can be produced from iron oxide in a blast furnace by the following reaction

3 C + 2 Fe 2 O 3 → 4 Fe + 3 CO 2

In this reaction, iron oxide (Fe 2 O 3 ) gives away its oxygen to carbon (C). In chemical terms, the carbon is said to be oxidized because it has gained oxygen. At the same time, the iron oxide is said to be reduced because it has lost oxygen.
