i did have a reaction with chromate too, but i had another with clear sodium carbonate and aluminum nitrate and got an orange ppt. I was thinking it could be Al2O3? i just don't know how that could occur.

I'm having extreme difficulty identifying some precipitates I obtained from combining a solution of Aluminum Nitrate and Sodium Carbonate. The result was an orange precipitate. I have searched high and low (complex ions, decomposition, redox, etc) but I can't figure it out. Please HELP!

Homework Statement getting confused with integration of trig functions. I am finding the integral of sinhx/1+coshx and I'm not sure how to start. should i use an identity? help is appreciated! Homework Equations possibly an identity of some sort? The Attempt at a Solution ?

thanks so much!

ok, thanks, what about dividing them? do i still use rules of differentiation. for example, 3^x/4^x

i'm working on the B) one

Having some trouble understanding derivatives including numbers to the "X" power. For example, f(x)= 7^8^x, f'(x)=? help please!
