Ok, so f(25)=(25^2+1)/2. 626/2=313. So, a=313. When substituted, 61-313 is -252. There's a small issue though. This question is multiple, and I don't see a -252 as one of the choices: a. -14 b. 36 c. 68 d. 77 e. 86 Did I do something wrong?

When I worked the question I got cu = 0.0196 and o= 0.0196 so the empirical formula is CUO

Ok what I did wrong was say 48 O atoms instead of just 3. Thank you very much

I got that as well but then I took the molar mass and divided by the empirical formula and got C8H10N4O2

So this is what I did 1E6kg x 1 mole Fe/55.85g= 17905 moles Fe 17905 mole Fe x 1 mol Fe2o3/2mol Fe *159.70g/1moleFe2O3* 1kg/1000= 1429kg

I did Zn(2)=65.39 then I divided that by the amu of Zn(NO3)2 x 100 is that right

I don't understand how to work this problem can you help

is that with the requirement that each couple sit side by side?

why adding 1=I Rather then 1-i

I don't want the answer. Do I have to account for the molar mass of CO2 and O2.

DrBob222 I used 29.2 in Hg because my book gave me 1 atm = 29.92 in. Hg. But why did you use 1atm/760mm

Ahhhhh thank you!!!!! I was so frustrated

where did you get the 96.2
13 years ago
DrBob222 I think Im doing something wrong. When I worked this problem out I came up with the right answer but wrong units. 0.112L KOH x 0.100molKOH/LKOH x 1mol H3PO4/3 mol KOH x 0.01 L H3PO4/1 mol H3PO4 = 0.373 L H3PO4

So is it a problem if the conch of NH4NO3 was not given to me. Or do I just assume it's the same as the NH3

pH = pKa + log ([A-]/[HA]) pH = pKa + log ([C2H3O2-] / [HC2H3O2]) pH = -log (1.8 x 10-5) + log (0.50 M / 0.20 M) pH = -log (1.8 x 10-5) + log (2.5) pH = 4.7 + 0.40 pH = 5.1 I used this example And I still got it wrong it should have been 4.75 + 0.12 = 4.8...

No I'm sorry I just used this as the example of the H H equation

This what I did log(1.76 x 10-5) +log(0.150/0.200) = 4.879

DrBob I want to thank you SOOOOO much for all the help you give. I had never heard of the H H equation. And I also appreciate you patience

I'm stuck Ka=1.84 x 10-4= x x/ 0.125 (1.84 x 10-4)[0.125] 2.3 x 10-5= x = [H30] lost which way do I go

Don't think I know how to calculate the M of NH4NO3

Second thought I just don't understand what to do. pH= pKa + log [NH3]/[NH4NO3] pH= -l log ? + log (0.005/?) pH= ? pH= ?

ok DrBob the answer i got was 2.7 x10-5 am i correct

I can see that now thank you very much
