Answer 1

An oxidation-reduction reaction which is also known as redox reaction is a type chemical reaction that involves a transfer of electrons between two species.

Explanation:

An oxidation-reduction reaction which is also known as redox reaction is a type chemical reaction that involves a transfer of electrons between two species.

To identify oxidation and reduction we just need to remember "LEO" and "GER" which means LEO = Loss of electrons is Oxidation and GER = Gain of electrons is Reduction.

All redox reaction is a chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. They are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

There are thousands of an examples for oxidation and reduction reactions.

A good example of a redox reaction is the thermite reaction, in which iron atoms in ferric oxide lose (or give up) O atoms to Al atoms, producing `Al_2O_3`.

`Fe_2O_3(s)+2Al(s)→Al_2O3(s)+2Fe(l)`

Another good example is the reaction between hydrogen and fluorine in which hydrogen is being oxidized and fluorine is being reduced

`H_2 + F_2 -> 2HF`
