Question

Write balanced net ionic equAtions.

D) zinc chloride and excess ammonia

E) cupric phosphate and lots of ammonia

A) ammonia and excess zinc sulfate

Answer 1

What do you not understand? Can you write the balanced molecular equation?

Answer 2

I don't know what they form...

D) ZnCl2+ NH3--->


E) Cu3(PO4)2 +2NH4OH--->


A) NH3+ ZnSO4-->




I don't understand what it means by excess... How do I figure out what they form.

Answer 3

ZnCl2 and excess NH3 forms the ammine complex Zn(NH3)4Cl2
Cu ion reacts with NH4OH to form Cu(NH3)4^2+ complex ion.
NH3 and ZnSO4 does the same as ZnCl2 except it's Zn(NH3)4SO4 and not Zn(NH3)Cl2
