Gas devolve reactions are exothermic. So it is a exothermic too.

It dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns.
Exothermic reactions give out heat. some examples of exothermic reactions are : 1)burning fuel in a fire 2)the addition of acid to water 3)the thermite reaction(this one is quite a sight) 4)the haber process of producing ammonia Endothermic reactions take in heat from their environment. some examples of endothermic reactions are: 1)an ice cube melting 2)depressurising a can(responsible in part why deodorant feels cold) 3)dissolving ammonium nitrate in water 4)decomposition of mercury (II) oxide(this requires a lot of heat)
The reaction between aqueous ammonia solution and an acid is a neutralization reaction, where ammonia (a base) reacts with the acid to form an ammonium salt and water.
H2SO4 + 2 NH3 = (NH4)2SO4 You happy man/woman?

Vinegar and baking soda can be combined for a good endothermic reaction. Bleach and ammonia can be combined in small amounts in a well-ventilated area for a good exothermic reaction (although there are actually several reactions going on simultaneously).
This is an endothermic reaction. When barium hydroxide and ammonium chloride are mixed, they react to form barium chloride, ammonia, and water. This reaction absorbs heat from the surroundings, causing a decrease in temperature.
In this reaction the forward reaction, the one making the ammonia, is exothermic meaning it gives off heat when it reacts and heats up the surroundings. The backward reaction is endothermic meaning it takes energy from the surroundings to break the bonds between the Nitrogen and Hydrogen. The exothermic reaction is making bonds. (If you need something to remember this by, snap something. You need to put energy in to break it so breaking chemical bonds needs energy put into it. Endothermic.) If you heat the reactants you are putting energy in so you are increasing the endothermic reaction which is the one breaking the bonds between the Nitrogen and Hydrogen. So by increasing the amount of ammonia that has been broken by heating the reactants and increasing the backward reaction you decrease your yield (the amount of ammonia you get at the end).

The reaction between aqueous ammonia solution and an acid is called neutralization. In this reaction, ammonia acts as a base and reacts with the acid to form a salt and water.

Sodium bisulfite reacts with ammonia to form sodium sulfite, water, and ammonium bisulfite. The reaction is typically exothermic and can release heat.
Exothermic! Gosh. I had to change two answers which said "Endothermic" <object width="320" height="30"> <param value="http://images.mp3raid.com/i/mp3player.swf" name="movie" />
When sodium is treated with ammonia, the sodium dissolves in the liquid ammonia to form a deep blue solution called sodium amide, along with the release of hydrogen gas. This reaction is highly exothermic and should be carried out with caution due to the potential for a violent reaction.
