if 4.0 mol of a is reacted with 4.0 mol of b which of the reactant is limiting
a) b is limiting because 4. 0 mol and 6. 0 mol are needed.
b) a is limiting because 2 is smaller than 3 (the numbers refer to the coefficients the balanced equation).
c) b is limiting because 3 is larger than 2 (the numbers refer to the coefficients in the balanced equation)
d) a is limiting because 2 moland 4. 0 mol are needed. e. neither is limiting because equal amounts (4. 0 mol) of each reactant are reacted.

)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.
