130 is in Joules 7.20 and 25.0 are in MicroCoulomb and the answer has to be in cm

Here's what I have done... [OH] = 0.0344 pOH = -log(0.0344) = 1.463 pH + pOH = 14.0 pH + (1.463) = 14.0 pH = 12.537 Is this correct?

f(-3) = -3(-3)+5 = 9+5 = 14 now do the same for the rest.. f(x-3)= -3(x-3)+5 = -3x+9+5 = -3x+14

S (s) + O2 (g) --> SO2(g) 2SO2 (g) + O2 (g) <--> 2 SO3 (g) now using appropriate mol ratios you can solve... 3.4 x 10^24 S atoms (1 mol S/avagadros #)(2 mol SO3/1 mol S) then you can use the mols of SO3 to solve for g (using molecular mass) and then litre...

Nevermind. I solved this problem. For some reason I punched the wrong number into my calculator :)))

Delta T = Kf x molality 5.19 C = 5.12 C kg/mol x molality molality = 1.01 moles/kg Molality = moles solute/kg solvent 1.01 = moles solute/0.4 moles solute= .404 Moles solute=grams/molar mass .404=3.92g/molar mass molar mass= .103 I think I am still doing...

Oh snap. Thanks so much :D I knew I was doing something wrong.

Yes. It would be positive. Given the formula deltaG= delta(H)-Tdelta(S), a positive H minus Tdelta(S) with a low temperature has the ability to make delta G negative, but the greater the temperature, the more negative delta G becomes. The more negative de...

Well honestly all I've gathered from it is the general series of events. I also to an extent feel that it might perhaps be trying to discuss the problems of the working class, the usual mundane nature of someone jobs and perhaps poking fun at the fact tha...

3/180 * 100%= % of defective balls 300/1800 *100%= % of defective balls these two are the same (hence his prediction) so 100% - % of defective balls = % of balls that are not defective

0.30(30 carrots) + 3 = amount made on 30 carrots ($12) 555/12 = 46.25 sets of 30 carrots 46.25*30= 1387.5 carrots so he must sell 1388 carrots to earn $555

I know that temperature, polarity, and pressure are three of them. I was wonder what the other three are. I thought that maybe it might be stirring and the size of the molecule too. But then that means I'm missing one.
