Re: H20 in the ICE table
When doing an ICE table, do not include water, liquids, or solids, as these do not have concentrations.

Re: H20 in the ICE table
Yes, you should leave out H2O because we assume that it is in excess so the concentration doesn't affect the reaction.

Re: H20 in the ICE table
You include any gases, but since solids and liquids have negligible change they are not included in ice box or the equilibrium constant.
Re: H20 in the ICE table
when performing a ice table you should only worry about the gasses and aqueous molecules
Re: H20 in the ICE table
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.
Re: H20 in the ICE table
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.

Re: H20 in the ICE table
Leave out water, solids and other liquids but aqueous and gases can be used in the table

Re: H20 in the ICE 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.

Re: H20 in the ICE table
In addition to leaving out water, you should also leave out solids and liquids in the ICE table.

Re: H20 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

Re: H20 in the ICE table
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).

Re: H20 in the ICE table
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.

Re: H20 in the ICE table
yes you don't include water but also don't include other liquids and solids, just gases.

Re: H20 in the ICE table
whether we leave out water in the ICE table is dependent on the question, so make sure to read the chemical equation carefully.

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.
Re: H20 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
Re: H20 in the ICE table
You do not include liquids, solids, and water even in expressions. Aqueous is included though. Water in gas phase is included though.
