1. a sample consisting of 1.0 mol caco3 (s) was heated to 800oc when it is decomposed. the heating was carried out in a container fitted with a piston that was initially resting on the solid. calculate the work done during complete decomposition at 1.0 atm. what work would be done if instead of having a piston, the container was open to the atmosphere?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
