edit: not sure why this was moved to homework - it isn't.
Hi :) I'm a bit embarrassed to ask this, but I hope someone can set me straight. As a second year university chem student I feel I should know this.
In this question about thermal conductivity, I realize that it is a subject to itself...
Hello, I'm having problem finding tangential acceleration. I was trying to find some examples of this being done in my book and on the web, but I couldn't. So I hope someone can help me with this.
The problem is: "A point on a rotating turntable 20.0cm from the center accelerates from rest to...
Why do you have [H] = 2.148 x 10^-5?
pH = -log[H]
4.668 = -log[H]
10^-4.668 = [H]
edit: Oh lol, I should've put that in my calculator before posting.. they're the same thing. I wasn't thinking straight.
For the first one, the HCl is in excess, so all of the base will be used up. You need to calculate the total number of moles of the base and the HCl (n/V=M), then subtract the moles of HCl by the moles of the weak base, and use that to calculate the amount of H+ produced. Don't forget to adjust...
I'm trying to conceptually understand a question that I was wondering about while reading about Acid and Base Equilibria.
Since a strong acid such as HCl completely reacts to give Cl- and the hydronium ion, and Cl- is then inert, then the only equilibrium going on is Kw. Kw = KbKa =...
Thanks for the help guys.
My friend gave me the answer from the solutions manual. The part I was missing was this:
Assume there are 100 grams of CO and CO2. This will give the number of moles of CO and CO2. The number is arbitrary, but any chosen number will result in the same...
Hi, I'm completely out of ideas for this problem, and any help would be really appreciated.
At 850 degrees C and 1 atm pressure, a gaseous mixture of carbon monoxide and carbon dioxide in equilibrium with solid carbon is 90.55% CO by mass. Find the equilibrium constant...
I already know the answer to this but I still have a question about how to understand this stuff for my upcoming quiz.
Two reactants, A and B, are mixed, and the reaction is timed until a color
change occurs. The data are as follows:
[A] [B] Time (s)
0.100 0.140 25
0.050 0.140 50...
