When heated, aqueous silver chlorate, AgClO3, produces solid AgCl, and O2. How do i know if this is endothermic or exothermic? Which one is it and how do i tell?

If you have to heat it, it's endothermic. An exothermic reaction occurs spontaneously and gives off heat.

Endothermic means the reaction requires energy, as a catalyst, to occur. Thus, if you were to heat an element, molecule, etc. the reaction resulting would be an endothermic reaction.
Exothermic means the reaction releases energy when it occurs. These types of reactions usually occur when highly reactive elements or molecules come in contact with each other. In this scenario, a reaction will occur immediately, usually releasing energy in the form of heat or flame.
The reaction you described would be an endothermic reaction because heat is required for its completion.

exothermic rxn gives up energy (gets hotter).. reactions that are transferes energy FROM reactants like heat.....
endothermic rxn absorbs energy( gets colder)... transfers energy TO the reactants....

it needs heat
so it's an endothermic reaction

"When heated" means you are adding energy = endothermic
The reaction is a decomposition reaction which requires an input of energy in order to take place = endothermic
Either reason works; take your pick
