What does the k represent? So if x is a real number then the domain should include all reals? So basically to find the domain you should plug in some x's to see if they aren't real numbers? I fixed the (f/g) forgot to add the /4. What!?

Homework Statement Find a. (f+g)(x) b. (f-g)(x) c. (fg)(x) d. (f/g)(x) f(x)=2x-5 & g(x)=4 Homework Equations (f+g)(x)=2x-1 (f-g)(x)=2x-9 (fg)(x)=8x-20 (f/g)(x)=2x-5/4 The Attempt at a Solution When I've completed all the other equations, I'm stuck on domain. I'm thinking that its all...

What do you do when the pH is given, but you have to find the molarity?

Thank you I wrote down the equations that were listed on the website.

Actually, haha Tritation curves come up later up in the chapter. Thanks for the explanation. Now I can have an early understanding for them. Could someone explain Henderson-Hasselbach though, this doesn't seem to be in my notes. Also what is RICE?

Cool, just had chemistry today, went over the introductory parts of the unit. We've gone over the equation of the formation of water, and the conjugate bases, and acids of each acid or base. What are titration curves though?

thx for sharing, the lectures aren't exactly what I've been doing but it does help.

[SOLVED] Acids, Bases, and Salts I will be starting on a new chapter unit of Acids, Bases, and Salts for class. I was wondering what important information I should be aware of, like equations and laws since I want to stay ahead of my class, and not die if I miss a day.

I might not be familiar with gun laws but isn't that illegal?

I'm having trouble understanding the CNIE process. It would be very much appreciated if someone could show me how to solve a sample problem.
