Final answer:
Oxygen, nitrous oxide, and hydrogen peroxide are therapeutic gases known for their ability to oxidize substances or support combustion, used in various applications from medical treatment to fuel combustion.
Step-by-step explanation:
Therapeutic gases that will oxidize or support combustion include oxygen, nitrous oxide, and hydrogen peroxide. Oxygen is well-known for supporting combustion and is a critical component in various oxidative reactions including medical applications and combustion engines. Nitrous oxide behaves similarly to oxygen when heated with combustible substances, making it a strong oxidizing agent. It can decompose to form oxygen, thus supporting combustion even more effectively than air. Lastly, hydrogen peroxide is a powerful oxidizing agent capable of producing free radicals that damage cellular structures but is also used as a disinfectant due to its oxidizing properties.
