WHY CARBON IS NOT USED TO REDUCE THE OXIDE OF MERCURY (HgO) WHILE CARBON IS USED TO REDUCE OXIDES OF
ZINC????
Answers
the metal oxides and then reduced to the corresponding metals by using suitable reducing agents such as carbon,e.g .zinc metal can be obtained from it's oxide

hope it helps u dear✌️✌️✌️✌️
Answer:
IF you will observe the reactivity series properly, you will find that mercury is less reactive than zinc. Mercury is even less reactive than hydrogen. So it do not possesses a strong ionic bond between the mercury and oxygen atoms and hence only heating can do the reduction. If you want you can use carbon here to reduce but think the oxygen will get wasted be forming carbon dioxide gas. Reduction with carbon will also increase the expenditure to extract mercury. The main concept is that as mercury is very less reactive, only heating can thermally decompose Hydrargyrum oxide or Mercury oxide ( HgO) to mercury and oxygen. is any doubts, you can ask me.
