Question
How many types of oxides form when carbon reacts with oxygen?
- 4
- 3
- 1
- 2
Hint:
2 types of oxides are formed.
The correct answer is: 2
Carbon forms two oxides namely carbon monoxide and carbon dioxide when it with oxygen. Carbon dioxide is the only oxide formed when carbon is burned in an excess of air.
C + O2 ---> CO2; with excess oxygen
2C + O2 ---> 2CO; with less oxygen
