Endothermic.
After a chemical reaction the reactants are transformed in products.
A chemical reaction is categorized as a precipitation reaction when it involves the formation of a solid precipitate. This occurs when two aqueous solutions react to produce an insoluble product that separates out as a solid. The solid precipitate typically forms due to the combination of ions from the different solutions.
In a chemical equation you have the reactants on the left hand side of the arrow and the products on the right. The products are what you get after the reaction occurs. A + B -> C + D The products are C and D.

Precipitation in the water cycle occurs when water vapor condenses from the air and falls as water or ice. Normally this is caused by cooling either from an air mass or from a temperature drop at higher altitude. Precipitation in a chemical reaction occurs when chemical products are insoluble in a solution, or when the solution cannot hold the total volume of solutes present.
A precipitation reaction is usually a double displacement reaction. The ions that do not form the precipitate usually form the solution.
