Question
Burning of fossil fuels in inadequate oxygen releases____.
- Carbon monoxide
- Methane
- Carbon dioxide
- Nitrous oxide
Hint:
Carbon monoxide is created during combustion if there is not enough oxygen available.
The correct answer is: Carbon monoxide
- The main ingredients in coal are carbon, water, hydrogen, and oxygen.
- The majority of the carbon in coal is bonded, with one C-C bond present for each carbon atom.
- When a C-C bond is broken, energy is released. For every 23g of carbon that is burned, about 43g of carbon dioxide is created.
- Carbon monoxide, a colorless, odorless, and exceedingly hazardous gas is created during combustion if there is not enough oxygen present.
