Question
What are the product A and B in the following reaction:
- Silicon carbide
- Silicon carbide and carbon monoxide
- Silicon carbide and carbon dioxide
- Silicon trioxide and carbon
Hint:
The silicon attaches with carbon and a toxic gas is released.
The correct answer is: Silicon carbide and carbon monoxide
The correct option b)Silicon carbide and carbon monoxide.
SiO2 +3C --> SiC + 2CO
When silicon oxide reacts with carbon it gives silicon carbide and releases carbon monoxide.
