1. BrittanyFrench

i'm here

2. ghazi

\[KMnO _{4}+FeSO _{4}+H _{2}SO _{4}-->MnSO _{4}+Fe _{2}(SO _{4})_{3}+K _{2}SO _{4}+H _{2}O\] this one , please help me in balancing

3. BrittanyFrench

Okay well first you should split the things up and see how many of it you have, for example: K=1 Mn=1 O=12 Fe=1 S=2 (these are the products) and the reactants are: Mn=1 S=5 Fe=2 H=2 O=17.... Can you tell me which one's are already balanced??

4. ghazi

well i thought we need to balance ions first , by breaking MnO4 ion and so on

5. BrittanyFrench

no.. that's not it at all, you're making it more difficult.. The coeffients are the bottom numbers, Here I'll draw it for you hold on

6. ghazi

first of all i guess we need to see to which one is reduced and which one is oxidised and so on :(

8. BrittanyFrench

|dw:1356235962805:dw| Oh you just want me to balance it then get it to you??

9. ghazi

10. BrittanyFrench

alright, give me awhile sometimes these things can be tricky!!

11. ghazi

sure i dont think you will take much time :)

12. BrittanyFrench

18. BrittanyFrench

Geez, this is harder then I thought!!

19. ghazi

20. BrittanyFrench

Oh yeah still working on it.. But dang!! So many Oxygens and everything.. Jesh!

21. ghazi

lol keep it up

22. BrittanyFrench

:)

23. BrittanyFrench

oh my goodness, somebody else may need to help you, I can't figure this out!! This one's a little harder then I though!!

24. ghazi

hey what is the oxidation state of Mn in KMnO4? and Fe in Fe(SO4)2

25. BrittanyFrench

Yeah I didn't get into all tht my teacher just had me balance them not all that jazz

26. ghazi

lol without knowing oxidation state you cant balance it, i thought you knew it , its okay i have questions in stochiometry

27. BrittanyFrench

k, I'll try i'm headed off soon.. Not feeling good and really sleepy

28. ghazi

okay, i have lot to ask, not today may be tomorrow :) but i will :) dont worry :D and thanks for help

29. BrittanyFrench

30. ghazi

thanks madam, i can ask it after christmas , is that okay?

31. BrittanyFrench

no prob, and yeah I don't care. I 'll be on Wednesday hopefully

32. ghazi

okay can you help me a basic of stiochiometry nothing numerical just concept a bit please

33. BrittanyFrench

The concept of stiochemtry..

34. ghazi

yes the name why it is so ?

35. BrittanyFrench

I don't think you can find out why it's called that.. because i'm not sure why it's named that

36. ghazi

okay here is the question :D :D A sample of Na2CO3.H2O weighing 0.62 g is added to 100 ml of 0.1 N H2SO4. Will the resulting solution be acidic, basic or neutral ?

37. ghazi

stoichio means quantity of substance and metry means measurement but i am unable to correlate these , hope you can but help me with numerical one

38. BrittanyFrench

Oh my word, You must be doing something different I didn't learn that...

39. ghazi

i'm in learning period and you have been through it

40. BrittanyFrench

I'm not finished! got like 4 weeks left

41. ghazi

but it is of first 2 weeks i guess

42. BrittanyFrench

Nope, not for me

43. ghazi

i guess for you too, okay fine i stop it here :) thanks :D
