Aqueous Reactions: Mercury(I) Nitrate   
(Movie/Animation, Audio/Visual (8))
Reactions of solutions with aqueous Mercury (I) Nitrate.
Aqueous Reactions: Mercury(II) Ion   
(Movie/Animation, Audio/Visual (8))
Reactions of solutions with aqueous Mercury (II) Ions.
Vapor Pressure   
(Movie/Animation, Audio/Visual (5))
Pressure exerted by vapor of several organic substances is demonstrated using barometers. Molecular models of the substances are shown.
Structure-Property Relations for Alkanes and Alcohols   
(Movie/Animation, Audio/Visual (4))
Boiling points of alkanes, miscibility of alcohols, and the vapor pressure and viscosity of several organic compounds are demonstrated.
Barometer   
(Movie/Animation, Audio/Visual (3))
The use of a mercury barometer to measure air pressure is demonstrated.
Constructing Mercury Barometers   
(Movie/Animation, Audio/Visual (3))
Barometers are constructed using glass tubes filled with mercury. Two methods are used to fill the tubes and differently shaped tubes are used.
Reactions Under a Microscope   
(Movie/Animation, Audio/Visual (2))
Microscale redox and precipitation reactions.
Thermochromism: Mercury(II) Iodide   
(Movie/Animation, Audio/Visual (2))
When red-orange Mercury(II) Iodide (HgI2) is heated, it undergoes a phase transition at 126oC to a pale yellow form. As the heated sample cools, it gradually returns to the original red-orange color.
Reaction, Microscale: Mercury With Silver Nitrate   
(Movie/Animation, Audio/Visual (2))
A droplet of mercury is carefully combined with a solution of silver nitrate under a microscope.
Pressure   
(Movie/Animation, Audio/Visual (1), Movie/Animation (1))
Use of a mercury barometer and a McLeod gauge manometer are demonstrated.
