B is true as well as E, thank you for your help

positive ions that were removed from the cathode

updated this with the pic...and the second half reaction

Homework Statement The vapor pressure of water at 25.0 C is 23.8 torr, and the heat of vaporization is 43.9 kJ/mol. What is the vapor pressure (atm) of water at 59.8C?Homework Equations Clausius-Clapeyron equation. ln(P2/P1)=(ΔH/R)((1/T1)-(1/T2))The Attempt at a Solution P2=? P1=23.8 torr =...

thanks you . .

so the longest chain has 8 carbon atoms, with an ethyl group coming off the 3rd atom, and a methyl group coming off the 5th atom. SO... 3-ethyl 5-methyl octane ?

Homework Statement Enter the name for the above alkane. Homework Equations How to count Carbons and Hydrogen's. The Attempt at a Solution My answer was "Undecane" because I counted 11 Carbons and 24 Hydrogens but it says I am wrong. Any Idea?

yess, thanks a lot once again appreciate your patience, and 2 thumbs up from me lol

so now this means [ going back to the original problem] that since: h(t) = ef(t) and h'(t) = f'(t)*ef(t) h'(t) = a(t)*eA(t) -A(c) ?

ok well since its a constant then like you said the derivative is zero. [ i wasn't grasping the whole a(c) is a constant part] which leaves the derivative of f(t) = a(t) only? and i appreciate you being patient with this, i probably would of stopped helping by now :yuck:

well since A'(t) = a(t) then wouldn't the derivative of f(t) just be A'(t) and A'(c)? so: f(t)=A(t)-A(c) f'(t) = a(t) - a(c) ? **The main problem is I am in Calc C and all this stuff was stuff I did in Calc B, which was all the way back in Feb.**

alright, this isn't really helping [maybe I'm just not getting it] but thanks for trying, appreciate it.

ya I understand that, part 2 of the Fund thm of calc. but can u please explain your whole process on what your doing here cause your just pulling out these rules which still don't help me understand the process of setting this up.

so basically f(t) = Integral from c to t of a(s) f(t) = a(t) - a(c) then f'(t) = ??
