Hydrogen and chlorine cannon animation
This brief animation illustrates the chain reaction that occurs when hydrogen and chlorine gases react.
Burning of sulfur to produce sulfur dioxide
Sulfur is burned in a deflagrating spoon in a flask, forming sulfur dioxide in the synthesis reaction.
Reaction of magnesium with carbon dioxide
The reaction of magnesium with carbon dioxide (dry ice) is demonstrated. Despite the absence of air, the magnesium continues to glow.
Oxidation and reduction of copper
A piece of copper metal is heated in a flame and oxidized to black copper oxide by air. The oxidized copper is reduced when placed in a hydrogen atmosphere. When removed from the hydrogen atmosphere, the metal is again oxidized.
Exploding soap bubbles filled with hydrogen alone
Hydrogen-filled soap bubbles are ignited producing small explosions.
