The correct answer is B. Low purity oxygen.<\/p>\n
Oxidation is a chemical reaction that involves the combination of oxygen with another substance. This can be a simple reaction, such as the burning of wood, or it can be a more complex reaction, such as the oxidation of iron to rust.<\/p>\n
The amount of oxygen required for oxidation depends on the substance being oxidized. Some substances, such as metals, require a lot of oxygen to oxidize, while others, such as carbon, require very little.<\/p>\n
The type of oxygen used for oxidation also depends on the substance being oxidized. Some substances, such as metals, can be oxidized with air, while others, such as carbon, require pure oxygen.<\/p>\n
Low purity oxygen is often used for oxidation because it is less expensive than pure oxygen. It is also less likely to cause explosions, which can be a problem with pure oxygen.<\/p>\n
Hydrogen, sulphur, and nitrogen are not typically used for oxidation. Hydrogen is a flammable gas, so it is not safe to use for oxidation. Sulphur is a non-metal, so it does not react with oxygen easily. Nitrogen is an inert gas, so it does not react with anything.<\/p>\n","protected":false},"excerpt":{"rendered":"
