Lead into silver nitrate solution
Lead metal is placed in a silver nitrate solution.
reactions
Reaction of zinc with iodine
Granular zinc and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
Zinc iodine reaction
Powdered zinc and solid iodine are mixed and no reaction is observed. Adding water to the mixture initiates a reaction.
Burning of sulfur to produce sulfur dioxide
Sulfur is burned in a deflagrating spoon in a flask, forming sulfur dioxide in the synthesis reaction.
Aluminum iodine reaction
Powdered aluminum and solid iodine are mixed and no reaction is observed. Adding water to the mixture initiates a reaction.
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.
Hydrogen and chlorine cannon
Hydrogen and chlorine gases can be mixed together without reacting, but when the mixture is struck with bright light, it reacts explosively.
Ammonium dichromate volcano
Ammonium dichromate decomposes to form nitrogen, water vapor, and chromium(III) oxide.
Hydrogen and chlorine cannon animation
This brief animation illustrates the chain reaction that occurs when hydrogen and chlorine gases react.
Nitrogen triiodide detonation
Simply touching dry nitrogen triiodide with a feather causes it to explode. Includes slow-motion replay of explosion.
