Okay so the original equation is
ZnSO4(aq) + 2NH3(aq)? + 2H2O(l) Zn(OH)2 + (NH4)2SO4
Net ionic would be:
Zn2+ + SO4^2- + 2NH3 + 2H2O Zn2+ 2OH- + 2NH4 + SO4^2-
2NH3 + 2H2O 2OH- + 2NH4
is this correct?
I need help with these:
2/3 b+ 4 = 5
a/4 - 2 = 3
1/5 z- 1 = 3
- 1/5b - 2/5 = -2
3/4 f+ 5=-5
7b +6 = 2b - 19
And what I mean is can you please solve them on a piece of paper and take a picture of it and upload it here because I wont understand it if you explain it on here. Please help I could...
Please explain, because I don't know how to do this. Thanks!
A small corporation borrowed $1,500,000. Some of the money was borrowed at 7%, some at 8%, and some at 10% interest rate. Use a system of equations to determine how much was borrowed at each rate if the annual interest was $130,500...

I found many similar books but not this one. Let me know if you have this exact book in torrent or where I can download it. thanks
Or maybe a link to a pdf file.
