Give examples of the formation of carbon dioxide: a) In natural processes, b) in industrial processes, c) in the laboratory.

Carbon dioxide – carbon dioxide, is formed in natural processes during the life of animals. An animal, including a person, inhales air that contains oxygen and exhales carbon dioxide.
In industrial processes, carbon dioxide is emitted from the combustion of any substance that contains carbon in its warehouse. For example, when coal is burned, carbon dioxide is released.
In the laboratory, carbon dioxide can also be obtained by burning organic matter. When diluted hydrochloric acid and calcium carbonate react in the laboratory, carbon dioxide is obtained.
