The flame in a torch used to cut metal is produced by burning acetylene (c2h2) in pure oxygen. assuming the combustion of 1 mole of acetylene releases 1251 kj of heat, what mass of acetylene is needed to cut through a piece of steel if the process requires 20.7 × 104 kj of heat?

)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.
