An example of a synthesis is the statue of liberty turning green. oxygen in the air combines with the copper statue to form copper oxide, which is green. which of these is the correct chemical reaction for this?

a) cu + o → cuo
b) cu + o2 → cuo
c) cuo → cu + o2
d) 2 cu + o2 → 2cuo

D. 2Cu + O2 = 2CuO

Explanation:

Then CuO, which is black, reacts with CO2 to form CuCO3 which is green.

Answer : The correct chemical reaction is, (D)

Explanation :

Synthesis reaction : It is defined as a chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

When copper react with an oxygen then it react to give copper oxide as a product.

The balanced chemical reaction will be:

Hence, the correct chemical reaction is, (D)
