What are the balanced ionic equations for the following?

Question

sodium hydroxide with:

copper (ii) nitrate

iron (iii) nitrate

zinc (ii) nitrate

calcium (ii) nitrate

ammonium nitrate

ammonia with:

copper (ii) nitrate

iron (iii) nitrate

zinc (ii) nitrate

calcium (ii) nitrate

ammonium nitrate

Answer 1

sodium hydroxide with:

copper (ii) nitrate

2NaOH &  Cu(NO3)2 --> 2NaNO3 & Cu(OH)2 (s)

iron (iii) nitrate

3NaOH &  Fe(NO3)3 --> 3NaNO3 & Fe(OH)3 (s)

zinc (ii) nitrate

2NaOH &  Zn(NO3)2 --> 2NaNO3 & Zn(OH)2 (s), but with more (OH-):

4NaOH &  Zn(NO3)2 --> 2NaNO3 &   Na2[Zn(OH)4]

calcium (ii) nitrate

2NaOH &  Ca(NO3)2 --> 2NaNO3 & Ca(OH)2 (s)

ammonium nitrate

NaOH &  NH4NO3 --> NaNO3 & NH3 & H2O

(some people still write NH4OH instead of NH3 & H2O)

===================================

ammonia with:

copper (ii) nitrate

Cu(NO3)2 & 2 NH3 &2 H2O --> 2 NH4NO3 & Cu(OH)2 (s) , but add more:

Cu(NO3)2 & 4 NH3  --> 2 (NO3)- & [Cu(NH3)4]-2

iron (iii) nitrate

Fe(NO3)3 & 3 NH3 & 3H2O --> 3 NH4NO3 & Fe(OH)3 (s)

zinc (ii) nitrate

Zn(NO3)2 & 2 NH3 &2 H2O --> 2 NH4NO3 & Zn(OH)2 (s)

calcium (ii) nitrate

Ca(NO3)2 & 2 NH3 &2 H2O --> 2 NH4NO3 & Ca(OH)2 (s)

ammonium nitrate --> no reaction
