Consider the following reaction: Xe(g) + 2 F2(g) ⇋ XeF4(g)
A reaction mixture initially contains 3.33 M Xe and 4.44 M F2. If the equilibrium concentration of Xe is 1.96 M, what is the equilibrium constant (Kc) for the reaction.

Enter your answer with 3 digits after the decimal.

)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.

Asample of hydrated tin (ii) chloride (sncl2) has a mass of 4.90 g. when it is dehydrated, it has a mass of 4.10 g. which is the correct chemical formula for the hydrate? sncl2•2h2o          sncl2•4h2o          sncl2•6h2o

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
