Answer 1

Explanation:

please mark as best answer and thank me please

Answer 2

This is the oxidation-reduction chemical reaction.

• When oxygen is passed over red ,hot copper then the product formed will be copper oxide . This type of chemical reaction is known as the oxidation-reduction reaction.

• This also called combination reaction or synthesis reaction.

• It is called redox reaction as in this the two elements are there ,out of which the more electronegative element gets reduced and less electronegative one gets oxidised.

• Here in this reaction , 2Cu + O2 → 2CuO , Cu is oxidised and the oxygen gets reduced.
