Question

Formation of CUo from copper and oxygen denotes

Answer 1

Explanation:

Oxidation and reduction process takes place in a reaction simultaneously. ... Cuo+H2 ====>Cu +H2O is a redox reaction.

Answer 2

The formation of CUo from copper and oxygen denotes a redox reaction or combination reaction that occurred.

• In a redox reaction reduction of one substance and oxidation of other substances takes place simultaneously.
• Redox reactions are of many types such as combination reactions, decomposition reactions, displacement reactions or double displacement reactions.
• CUO is formed from Cu and O2. so, the reaction is 2Cu + O2 ------> 2CuO
• Here, the oxidation state of oxygen is changed from 0 to -2 so oxygen is reduced.
• Similarly, the oxidation state of cu is changed from 0 to +2 so, cu is oxidised.
• This reaction is an example of a combination reaction as two reactants combined to form a single product.
