Oxygen is a tasteless gas. It is part of the stellar life style. Without oxygen, humans would more than likely die. It is found on the human body, the Sun, oceans, and the atmosphere. It's used to make acid, sulfur acid, nitric acid, and other compounds. Oxygen is very useful in hospitals because it allows patients, who have a hard time breathing, breathe. It is also used to treat victims of carbon monoxide poisoning.
