This is an endothermic reaction.
exothermic
An exothermic reaction is one that proceeds with the evolution of heat.
Heat is not any kind of "bond"; it is energy.
There is no symbol that will show weather or not heat is needed in a decomposition reaction.

exothermic
'Thermic' means heat. Thus an 'exothermic' reaction produces heat, while an 'endothermic' reaction absorbs heat.
An exothermic reaction is one that proceeds with the evolution of heat.
The reaction is dehydration.

Decomposition!
Whenever direct heat is given to any kind of particles/materials, an exothermic reaction occurs. When an exothermic reaction occurs, heat is released. This is what causes the particles to heat up.
Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic reaction.
its a chemical reaction. in addition to heat and light, a new gaseous substances are formed
