The correct answer is C. nitrous oxide. Nitrous oxide, also known as laughing gas, is a gas that is used as an anesthetic. It is inhaled and can cause a feeling of euphoria and relaxation. It is often used in dentistry to numb the pain of dental procedures.
Oxygen is a gas that is essential for life. It is used by the body to produce energy. Nitrogen is a gas that makes up about 78% of the Earth’s atmosphere. It is not used as an anesthetic. Chlorine is a gas that is used to disinfect water and to make bleach. It is not used as an anesthetic.
Nitrous oxide is a safe and effective anesthetic. It is used by millions of people each year. It is important to note that nitrous oxide is not a substitute for general anesthesia. General anesthesia is a much more powerful anesthetic that is used for major surgery.
