Identify B in the following reaction,

{\mathrm{H}_4}\mathrm{Si}{\mathrm{O}_4}\xrightarrow[{ - {\mathrm{H}_2}\mathrm{O}}]{{1000^\circ C}}A\xrightarrow[\Delta ]{{\mathrm{Carbon}}}B + \mathrm{CO}

View answer and explanation

Correct option: D

Carborundum

Option D (Carborundum) is correct because heating H4SiO4 at 1000°C gives silica (SiO2), which reacts with carbon at high temperatures to form carborundum (SiC).
