I had a feeling I'd be stuck like that. oh well... thanks for the help

Yep... so... if n=10 and I know all my [math]A_i[/math], it's going to be a pain in the bum to find x, you're saying?

Thanks for the advice [math] \sum_{i=0}^n A_i (1+x)^{-i} = 0 [/math] I forgot the = 0. Is there a way I can solve that one?

In the attached equation, is there any way to analytically solve for x?

Do gases of different molecular weights separate like liquids would? Mainly I'm thinking of gases like Cl2 and H2. Would the H2 gas form a "layer" on top that I could release from a container? I ask because I found when electrolyzing salt water it can produce Cl2 and H2, and also that when these two are exposed to sunlight and each other they can "explode to form HCl." I don't want an unsupervised explosion...

Would this be the oxide or the pure metal?
