Just want to make sure that I am thinking of this right. When using an ICE chart to find the equilibrium concentrations we do not include any solids or liquids since those compounds are not included in solving for the equilibrium constant.
Yes, so because substances as solids and liquids don't really change very much in molar concentration in a reaction, we don't use them to calculate K at all, so therefore we do not need to pay attention to them in our ICE chart bc they're not going to be used in our K equation anyway.

can you (or anyone else who reads this) please explain this a bit more? i thought for the sake of this class we only take into consideration gases when calculating for K?
Yes, you do not need to include the concentrations of solids or liquids in the ICE box chart as their concentrations do not change significantly to the point where they would have an affect on K.
That's correct. The purpose of using ICE tables is to find concentrations of reactants/products at equilibrium so that we can solve for K (if the question asks to solve for K). And, as we already know, solids and liquids serve no purpose when calculating K, so they can be left off the ICE table.
