Homework Help: Coming Up With Reaction Quotient

    Can't figure this one out. Here's the problem.

    Solid molybdenum (VI) oxide reacts with gaseous xenon difluoride to form liquid molybdenum(VI) fluoride, xenon gas, and oxygen gas. Write the Qc for this reaction.

    I know Qc is products over reactants and pure liquids and solids are not included.

    So this is what I came up with. Its wrong though.

    Qc= [XeF2]3 / [Xe]3 [O2]

    Any help would be great. Thanks.

    1. What is the balanced reaction equation?

    2. If it is products over reactants, why do you have XeF2 - a reactant - in the numerator?
