How does potential energy become kinetic energy? Select one
a. Potential energy has no relation to kinetic energy
b. Potential energy becomes kinetic when an object remains in place and continues to build up more and more energy
с
When something hot touches something cool, the potential energy in the hot object is turned into kinetic energy in the cool object
When an outside force acts on an object with potential energy, that force turns the potential energy into kinetic energy

One of the few xenon compounds that form is cesium xenon heptafluoride (csxef7). how many moles of csxef7 can be produced from the reaction of 13.0 mol cesium fluoride with 12.5 mol xenon hexafluoride? csf(s) + xef6(s) csxef7(s)

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

What is the average rate of the reaction between 10 and 20 s?
