Question

Please help to tell me if i did these Net Ionic Equations correctly?
The things underlined in green were given...and red is me balancing.

Answer 1

Is NH3 a weak base or a strong base?

Answer 2

weak...shoot its not supposed to dissociate is it? so it would be
NH3 --> N4- + 4H+

Answer 3

You are correct that NH3 would not dissociate. Is NH4 a strong or weak acid?

Answer 4

weak so it would stay NH4 then as well right? i forgot about that

Answer 5

Correct

Answer 6

ok thank you, are the others correct

Answer 7

Also, do you think you could help me check a few more? i just want to make sure i got these homework problems correct..

Answer 8

The others were hard to read.

Answer 9

Ok well don't worry about those, i looked them over again and i think they are good. can i put a few more up for you to look at...you don't have to look at all of them... but if you would justtake a peek it would be nice

Answer 10

Can you type it?

Answer 11

It would be too long to type

Answer 12

These pictures would be better though...i took them earlier

Answer 13

I don't see anything attached

Answer 14

I'm working on it sorry. Had to find the files on my mac.

Answer 15

4.95 I need the Concentration (M) of Fe2+
4.77 I need the Concentration of the final solution after the two solutions are mixed...i don't know how to figure this one out
4.89 is the Molar Concentration of KOH (KHP is Potassium Hydrogen Phthalate)
and 4.83 i need the grams of NaCl then i can do the Net ionic

Answer 16

4.89

18.68 ml is not 0.1868 L. Redo the ml to L conversion. Otherwise it looks good. For now, I can't look at the others. Maybe later or tomorrow morning.

Answer 17

The molar mass of KPH is not 204,23 g/mol. So the mol for KPH is incorrect.

Answer 18

Its KHP and it is 204.23...KHP is Potassium Hydrogen Phthalate

Answer 19

Our teacher gave us that information

Answer 20

You are correct. The formula for KHP is C8H5KO4. So your work is good, just correct the L conversion.

Answer 21

One slight thing you rounded the mol to 3 digits. The mol is 0.0020653, so if you are rounding to 3 digits 0.00206 is incorrect. You started with 4 sig figs, so you should probably round to 4 sig figs.

Answer 22

Ok, thanks...the reason i didn't do that is because my teacher doesn't really care as much about sig figs as he does about us getting the process correct

Answer 23

Ok. Then you're fine.
