J'y pense que c'est une réaction endothermique avec le metal est l'Urée refroidit

[LiLxRefuGe]

is that an exothermic or endothermic reaction?.. meaning is it hot or cold?

[kntshrm]

Exothermic. In practice, they add formaldehyde liquid to urea crystals, mix until dissolved & clear, then add a bit of conc. sulphuric acid perhaps as a catalyst. A dehydration reaction.
