Study Notes

Combustion Reactions

Introducing a glowing splint to oxygen gas causes a rapid combustion reaction, resulting in a burst of flame.
Igniting hydrogen in air produces a loud explosion, releasing a large amount of energy.

Effects of Gases on Combustion

Carbon dioxide gas extinguishes a flame, as it displaces oxygen, depriving the fuel of the necessary reactant for combustion.

Chemical Reactions

The reaction between carbon dioxide and limewater produces calcium carbonate, a white precipitate.

Combustion in Oxygen

Burning in pure oxygen results in a more vigorous reaction than in air, due to the higher concentration of oxygen available for combustion.
