Carbon

B

Carbon monoxide

C

Carbon dioxide

D

Calcium carbronate

Text Solution

Verified by Experts

The correct Answer is:
A
Carborundum is SiC. It is obtained by heating silica(`SiO_(2)`) with carbon in an electric furnace
`{:(SiO_(2)+2C to Si +2CO),(Si" +"C " "to SiC),(ulbar(SiO_(2)+3C to SiC +2CO)):}`
