One method of experimentally determining whether a species is paramagnetic is to weigh it in an instrument called a magnetic susceptibility balance. this is a balance with a strong electromagnet placed next to the sample holder. if the species is paramagnetic, the mass reading of the balance will increase when the field is switched on.
classify these species as paramagnetic or diamagnetic
which species will have the strongest mass shift on a magnetic susceptibility balance?

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
