is a chemical reaction involving the addition of oxygen.​

Answer 1

Answer:

1 - carbogen

2 - carbon dioxide

3 - oxidation reaction

Explanation:

1 - Carbogen is a mixture of carbon dioxide and oxygen (95% Oxygen / 5% Carbon Dioxide), it is used to stimulate breathing in the treatment of respiratory disease.

2 - A carbon dioxide (CO2) fire extinguisher is a portable, active fire protection device that works by expelling carbon dioxide onto a fire. It works by displacing the oxygen the fire relies upon to continue burning, and it is primarily used to extinguish fires in which the source of the fuel is a flammable liquid or gas.

3 - Oxidation means the addition of oxygen to a molecule or the removal of hydrogen from a molecule. Reduction means the addition of hydrogen to a molecule or the removal of oxygen from a molecule.
