what do I put instead of it, 1, or 0 o what?

@wolfe8 any ideas please?

wolfe8 · Answer

Wait what's an ICE again?

adamconner · Answer

how to calculate equilibrium concentration, where I is initial, C is change and, E is equilibrium

adamconner · Answer

I know that solids don't count in the equilibrium, but when I make the table, what do i substitute for it?

australopithecus · Answer

Well first off do you have initial and final concentrations?

australopithecus · Answer

These tables can see difficult at first but they are actually really easy

australopithecus · Answer

So much stuff exists online how to solve these just take the time to review other material http://chemwiki.ucdavis.edu/Physical_Chemistry/Chemical_Equilibrium/Le_Chatelier%27s_Principle/Ice_Tables

solids get completely ignored in equilibrium expressions, because the concentration of a solid (or a pure liquid, for that matter) don't change. You can substitute in a 1 for the concentration of the solid, but definitely not a zero.
