is H20 the only thing we leave out when doing an ICE table?

Yes, you will only use the other three compounds in an ICE table.

When doing an ICE table, do not include water, liquids, or solids, as these do not have concentrations.

Yes H2O is not included in the ICE tables along with solids and liquids.

I think you only include gases when doing an ICE

Yep! Leave out H2O, solids, and other liquids.

Yes, you should leave out H2O because we assume that it is in excess so the concentration doesn't affect the reaction.

Leave H2O out only if it is a liquid. It must be included if it is a gas.

I believe ICE table only pertains to gases

You include any gases, but since solids and liquids have negligible change they are not included in ice box or the equilibrium constant.

when performing a ice table you should only worry about the gasses and aqueous molecules

Typically in the textbook problems, water is seen in liquid form. Since liquid and solids are not included in ice tables, do not include water. However if water was in gas form and depending on the problem, I think you might have to include it.

Only if H20 is in the liquid form then do not include it in the ICE table but if it is in gaseous form then include it. Also, don't include any solids or liquids in the ICE table.

Leave out water, solids and other liquids but aqueous and gases can be used in the table

Leave out pure liquids and solids. Water as a liquid isn't included, because it remains in excess. Its acting as a solute and the changes in concentration of water are so minute we don't have to account for them.

In addition to leaving out water, you should also leave out solids and liquids in the ICE table.

When filling out and ICE table, only include gases and aqueous molecules. In addition to the comments above, you want to leave our solids because you cannot really condense or expand solids since they are in a fixed state

H2O could be included if it is in the gas phase and you are calculating Kp. Otherwise it should be excluded if it is liquid (which most of the time it will be).

In an ICE table we leave about liquids and solids. If the H2O is in gas phase then it will be included in the ICE table as well.

yes you don't include water but also don't include other liquids and solids, just gases.

whether we leave out water in the ICE table is dependent on the question, so make sure to read the chemical equation carefully.

Do not include H2O.

In ICE tables, you leave out liquids and solids, so if that water is in liquid form, you leave it out. If that water is in gaseous form, you do have to include it in the ICE table.

you leave out any molecule that is a pure liquid or solid. If H20 is in a gas phase, then it is included

you include gases as well as aqueous reactants/products

You do not include liquids, solids, and water even in expressions. Aqueous is included though. Water in gas phase is included though.
