Carbon dioxide is a gas that is produced when organic materials are burned. It is a major component of the Earth’s atmosphere and helps to regulate the planet’s temperature.
Nitrogen peroxide is a gas that is produced when nitrogen and oxygen are combined. It is a major component of air pollution and can cause respiratory problems.
