For each reaction
1. Balanced molecular equation
2. Identify the precipitate
3.Write a balanced ionic equation, showing all dissolved species as ions and all precipitates as molecules
4. Write balanced net ionic equation
A. NaOH+FeCl3----->
B.KOH + FeCl3---->
C.NaOH+CO(NO3)2---->
D. KOH+ CO(NO3)2---->
E.COCl2+NaOH----->
I have no idea what im supossed to do.

Things that you will need to solve each of these :
-- 1. Periodic table with ion charges; for example : http://www.sciencegeek.net/tables/PT_ion…
-- 2. Solubility chart : http://intro.chem.okstate.edu/1515SP01/D…
I will only show you how to do the first problem that way you can figure out the others :)
-- Balanced Molecular Eq.
NaOH (aq) + FeCl3 (aq) ----->3 NaCl (aq) + Fe(OH)3 (s)
The Fe(OH)3 (s) is the precipitate because according to the solubility
chart Fe3+ and OH- create a solid.
-- Balanced Ionic Eq.
3Na+ (aq) + 3OH- (aq) + Fe3+ (aq) + 3Cl- ----> 3Na+ (aq) + 3Cl- (aq) + Fe(OH)3 (s)
Since Fe(OH)3 reaction creates a precipitate it cannot completely dissociate like NaCl since it's an aqeous solution.
-- Balanced Net Ionic Eq.
3OH- (aq) + Fe3+ (aq) ---> Fe(OH)3 (s)
Hope this helps
