Question

"Oxidation and reduction process occur simultaneously."Justify the statement with example.

Answer 1

Yes this is right that oxidation and reduction processes occur simultaneously bcz if one element is oxidised, then one element would be reduced.

Answer 2

if oxidation and reduction takes place in a reaction then it is called redox reaction .When an element is oxidized another element is reduced
ex- CuO + H2 -------> Cu + H2O
here CuO is in the process of reduction and H2 is oxidizing
