Oxygen and Carbon Dioxide OXYGEN (O) Oxygen was discovered by a British chemist, Joseph Priestly in 1774, and independantly by Carl Wilhelm Scheele, a Sweedish chemist. Oxygen has many uses - it is used in welding torches, to assist in hospital patient's breathing and in metal fabrication industries. Oxygen is also used for defense purposes as a propellant for guided misiles and rockets CARBON DIOXIDE (CO2). Carbon dioxide was named "fixed air" by a Scottish chemist, Joseph Black. A French chemist, Antoine Lavoisier proved that "fixed air" is an oxide of carbon, by showing that the gas obtaine...
