https://en.wikipedia.org/wiki/Carbon_dioxide
Carbon dioxide is a chemical compound with the chemical formula CO2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO 2 is the primary carbon source for life on Earth.

Of the greenhouse gases, carbon dioxide (CO 2) is the most significant.Natural sources of atmospheric CO 2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms. These sources are balanced, on average, by a set of physical, chemical, or biological processes, called " sinks," that tend to remove CO 2 from

Carbon dioxide is a greenhouse gas. It absorbs and emits infrared radiation at its two infrared-active vibrational frequencies. The two wavelengths are 4.26 μm (2,347 cm −1) (asymmetric stretching vibrational mode) and 14.99 μm (667 cm −1) (bending vibrational mode). CO 2 plays a significant role in influencing Earth 's surface

The black is carbon and the red is oxygen. Carbon dioxide (CO 2) is a chemical compound and is acidic. It is a gas at room temperature. It is made of one carbon and two oxygen atoms. People and most animals release carbon dioxide when they breathe out. Also, every time something organic is burnt (or a fire is made), it makes carbon dioxide.
