The concentration and volume of reagents combined in each trial are listed in the table below: Trial 00020 M 00020 M H2O(mL) Fe(NO3)3mL) KSCN (mL) 1 5 2 3 2 5 3 2 3 5 4 1 4 5 5 0 Initially (right after combining and before any reaction occurs) the concent...

What is the pH of the solution created by combining 2.80 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)? with 8.00 mL of the 0.10 M HC2H3O2(aq)? mL of NaOH pH w/HCl pH w/HC2H3O2 2.80 ? ? okay, so i tried m1v1=m2v2 and when i got m2 i would i...

Balance the equation: Note: If a chemical species coefficient is "1" then "1" needs to be entered in the field before that species. __MnO4(–) + __H(+) + __C2O4(2–) __Mn(2+) + __H2O + __CO2 i need a check pls

i see what my problem is, thanks i got it.

iam confused with the ice table could you show me because my answer .0002 is incorrect thanks.

thanks but i figured how to do this

i inputed: -Log(5.20 x 10-4) ph=3.28 but its incorrect?

okay, i got 2.8E-4 mols of NaOH and 8e-4 MOLS of acetic acid, so do i just plug in mols of hcl into -log(hcl)?

need the check pls

thats not the ansr, need a check

on this one i got:2,16,2,2,8,4 but it say that the second(2)which is the coefficent for C204(2-) and the 4 on the co2 is wrong ? what might be the problem?

i got 1,8,1,1,4,1 but the second coeffient(one) and the last coeffient(one) are incorrect. im not sure what goes for ____Fe(2+) and ___Fe(3+)
