Paramagnetism: Nitrogen and Oxygen - Oxygen
The paramagnetism of liquid oxygen is tested.
oxygen
Water gas reaction
When water contacts burning charcoal, hydrogen gas and carbon monoxide gas form.
Exploding soap bubbles filled with hydrogen alone
Hydrogen-filled soap bubbles are ignited producing small explosions.
Exploding soap bubbles filled with hydrogen plus some oxygen
Hydrogen plus some oxygen produces louder explosions.
Exploding soap bubbles filled with hydrogen plus more oxygen
Hydrogen plus more oxygen produces even louder explosions.
