710 mmHg is the pressure (in mm hg) of the gas inside the following apparatus if the outside pressure, patm, is 740 mm hg and the difference in mercury levels is 30 mm hg
The separation of a single chemical compound (in this case, mercury(II) oxide) into two or more smaller compounds is known as chemical decomposition (in this example mercury and oxygen). There are several industries that employ mercury. It is utilised in electrical switches, thermometers, barometers, batteries, and the production of chlorine gas and caustic soda.
mercury in gas column is above the mercury that is open
So, pressure of gas is less than Patm use:
Patm = Pgas + h
740 mmHg = Pgas + 30 mmHg
Pgas = 710 mmHg
what is the pressure (in mm hg) of the gas inside the following apparatus if the outside pressure, patm, is 740 mm hg and the difference in mercury levels is 30 mm hg?
