Re: solving for q (grams vs mol)

I think it all depends on the problem you're given. You will just have to adjust your units given what you have and what you need and make that adjustment for each problem!

Re: Kw= 1.0 x 10^-14

The Kw value at 25C is 1.0 x 10^-14. It is also the designated value for Kw. Because water is neutral, it can be inferred that the [H3O+] and [OH-] concentration will equate to each other and have the same value, which is where 1.0 x. 10^-7 came from.

Re: Kw

Yes! The Kw value will change based off of the temperature, which in turn changes the pH of a solution. Water is considered neutral when the acid and base concentrations are the same, hence pH = 7.

Re: Chapter 5 question 61

Since the system is being compressed, which applies to pressure, we are only looking at moles of gas. Therefore, since there are 6 moles of gas on either side of the equation, the system would not favor either side when compressed. Why don't you take the six moles of gaseous water into account on t...

Re: Water in Excess

The general rule of thumb is to never take into account the liquids and solids, only aqueous compounds, because liquids and solids are incompressible and their concentration stays constant throughout the reaction. The concentration value of liquids and solids is so high that including them in the eq...

Re: Pure substances

For pure solid and pure liquid, active mass is taken to be unity, i.e., 1 as they remain constant throughout the reaction. In other words, pure liquids and solids are made up of one substance, hence they do not have a concentration because it doesn't change enough.

Re: Kc vs Kp

Yes it can! However, Kc should be used if all of the species in the equation are aqueous, you should be using Kc. When everything in equation is gases, either Kp or Kc can be used.
