Hydrogen
Hydrogen is a colourless and odourless gas. The gas is highly flammable and explosive. Hydrogen is produced in chemical plants and is used for the heat treatment and protection against oxidation of metal. Also the hardening (hydrogenation) of vegetable and animal oils and fats is carried out with hydrogen.
