Answer 2

Option D)  C + O2

C + O2  could be the chemical formula for a compound.

• Two oxygen atoms and one carbon atom make up the chemical structure of the gas known as carbon dioxide (CO2). Its capacity to absorb infrared waves makes it a significant greenhouse gas. The gaseous chemical molecule carbon dioxide is present in the atmosphere of the planet Earth.
• As carbon and oxygen combine to generate carbon dioxide, it is a combination reaction. It is a combustion reaction because oxygen causes carbon to burn.
• Atoms of carbon and hydrogen can be found in gasoline. Carbon dioxide is created during combustion when oxygen from the air and carbon from the fuel mix (CO2).
• One of the many greenhouse gases in the atmosphere is carbon dioxide (CO2). Because they act as a greenhouse's glass, allowing visible light from the Sun to pass through, but absorbing long-wavelength infrared radiation from the Earth and maintaining a warm atmosphere, these gases are also known as greenhouse gases.
