Endothermic
The ammonium nitrate dissolves.
Ammonium sulphate and potassium nitrate do not react. All that will happen is that the solution will contain separate ammonium, sulphate, potassium, and nitrate ions dissolved in an aqueous (water) solution.
Here I'll show you how to do it so that you are able to another one. NH4 = Ammonium NO3 = Nitrate Simple. Memorize your polyatomic ions. It REALLY helps. It is ammonium nitrate.
solution of bismuth nitrate and ammonium bicarbonate will react to form bismuth ammonium nitrate and CO2. If excess of ammonium bi carbonate is added possibility of ppt of bismuth sub carbonate is there.

The ammonium nitrate dissolves.
The silver in the Silver Nitrate precipitates the chloride ions out of the ammonium chloride solution, leaving Ammonium Nitrate in solution and a Silver Chloride solid.
The temperature of the solution decreases
the temperature of the solution decreases.
Evaporating slowly thee water ammonium nitrate is obtained.
If the silver nitrate and ammonium chloride are both in solution when mixed, the very sparingly soluble silver chloride precipitates as a solid, leaving ammonium nitrate in the solution.
Ammonium sulphate and potassium nitrate do not react. All that will happen is that the solution will contain separate ammonium, sulphate, potassium, and nitrate ions dissolved in an aqueous (water) solution.

Ammnium nitrate (NH4NO3) is a crystalline solid at room temperature.
Nitrate is a negative ion (anion), NO3-. It does not exist in isolation, but must be part of a compound with a positive ion (cation). Examples of nitrate salts are sodium nitrate, NaNO3-, magnesium nitrate, Mg(NO3)2 and ammonium nitrate, NH4NO3. These salts are solid at room temperature and water soluble. (When nitric acid, HNO3, dissolves in water the solution also contains the nitrate ion as well as hydrogen ions)
solution of bismuth nitrate and ammonium bicarbonate will react to form bismuth ammonium nitrate and CO2. If excess of ammonium bi carbonate is added possibility of ppt of bismuth sub carbonate is there.
