16. You have 2 beakers: one contains 30 g of water (1) at 60°C & the other has 30 g of ethyl alcohol (1) at 60°C. How many Joules of heat is required to heat each beaker up to 85 °C?
(Specific heat of alcohol: 2.44 J/(g*°C), Boiling point = 78.4 °C, Latent heat of Vap, = 841 J/g)

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.
