Combustion of Elements in Oxygen
Oxygen is a very reactive element. A substance burning in air is actually reacting with oxygen. The following elements react with oxygen in characteristic ways:
Magnesium
- Burns with a very bright, white flame.
Hydrogen
- Burns quickly, producing a loud squeaky pop.
Sulfur
- Burns with a blue coloured flame, producing a colourless gas.
