Pure solids and pure liquids have concentrations that are difficult to express (molar density?) and cannot be changed so they are simply left out of any equilibirum expression. Do I have Ksp video?
I have a double displacement reaction and it only gives me the moles for the reactants...do I put 0's in both spots(for the products) for the initial concentration? Thanks :)
@neverowned1 You'll have to determine which way the reaction will shift based on solving the equilibirum expression for the values given. After that, plug in (initial concentrations - x) on the side that will decrease and (initial concentrations + x) on the side that will increase - mind the stoichiometry (maybe 2x, 3x, etc.) After that, it's just algebra. Sorry, no time to post an example.

what if there was a solid in the products or the reactants??

howd he get the -0.0503

@jf1gd2 There is 1:3 stoichiometry between N2 and H2. So, if H2 is decreased by 0.151 then N2 must be decreased by one third that much . . . 0.0503.

what if u only get initial concentrations and none at equilibrium...use limiting reagent as x??? and solve? example plz.

@neverowned1 you would have to use the quadratic formula.
