; Carbon dioxide in earth's atmosphere is considered a trace gas currently occurring at an average concentration of about 385 parts per million by volume or 582 parts per million by mass. . Carbon dioxide is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Here, in a bowl-shaped depression of about 100 m diameter, local concentrations of CO2 rise to above 75% overnight, sufficient to kill insects and small animals, but warm rapidly when sunlit and disperse by convection during the day[24] Locally high concentrations of CO2, produced by disturbance of deep lake water saturated with CO2 are thought to have caused 37 fatalities at Lake Monoun, Cameroon in 1984 and 1700 casualties at Lake Nyos, Cameroon in 1986.

Humans take in oxygen and breathe out carbon dioxide. Today we know that gas is carbon dioxide. It acts as both a pressurizing agent and, when dissolved into the underground crude oil, significantly reduces its viscosity, enabling the oil to flow more rapidly through the earth to the removal well.

It's used by some dry cleaners for this reason. In rare circumstances, carbon dioxide can be a threat to life. It is often referred to by its formula CO2.

If organic chemistry is the study of carbon, then why isn't carbon dioxide considered to be an organic compound? What is 35 degrees Celsius in Fahrenheit? What is the exposition of the story of sinigang?
