Some Chemistry Equations I Need Help With?

Question

Just need some help with some ionic equations. Any help would be much appreciated.

CrCl3 + NaOH
KMnO4 + Glucose
KMnO4 + FeSO4
FeSO4 + NaSCN
CuSO4 + NaOH + glucose
Zn(NO3)2 + NH3

Answer 1

CrCl3 + 3NaOH --> 3NaCl + Cr(OH)3
KMnO4 + Glucose -->
2KMnO4 + FeSO4 --> K2SO4 + Fe(MnO4)2
FeSO4 + 2NaSCN --> Na2SO4 + Fe(CN)2 + S
CuSO4 + NaOH + glucose --> red
Zn(NO3)2 + 2NH3 -->2 NH3NO3 + Zn

Answer 2

1. precipitate of Cr(OH)3, followed by it re-dissolving
2. glucose reduces (MnO4)- to Mn2+
3. (MnO4)- oxidises Fe2+ to Fe3+
4. a blood-red complex forms if you really meant Fe3+, [FeSCN]2+
5. red precipitte of copper(I) oxide
6. precipitate of Zn(OH)2 followed by it re-dissolving to form an ammine complex.

Now you can look them up.
