This question is about the properties and reactions of several substances.?
Zinc salt “N” dissolves in water to form a colourless solution —> add dilute nitric acid and aqueous silver nitrate to form a white precipitate “P”.
Q1: Name the compound of the white precipitate “P”, name the compound of the white precipitate “O”, name the compound of the salt “N”.
Q2: Write the chemical equation for all the three reactions.
Q3: Name two substances you could react together to make zinc salt “N”.

“good luck!”, practice makes perfect!!.
The zinc + ammonia reaction could either be Zinc hydroxide which would be a precipitate or it could form a complex like Zn(NH3)2 + and then when you add more ammonia it turns into Zn(NH3)4 + and dissolves.
If the salt is ZnCl, you would just react Zn metal with Chlorine gas.
