They trapped a mixture of atmospheric air with additional oxygen in a test-tube (A) upside-down over a large quantity of dilute alkali solution (B), which in Cavendish's original experiment was potassium hydroxide,[14] and conveyed a current through wires insulated by U-shaped glass tubes (CC) which sealed around the platinum wire electrodes, leaving the ends of the wires (DD) exposed to the gas and insulated from the alkali solution. So let's say, 94 tour. The percentage of the world reserves located in the country with the largest reserves. www.opendialoguemediations.com. [7] Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature. Ramsay wrote to Rayleigh suggesting that he should look for a heavier gas in the nitrogen got from air, while Rayleigh should look for a lighter gas in that from ammonia. Density is a measure of the amount of mass contained in a unit of volume.The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions.
