Determine if the equation is endothermic or exothermic examples

There are a couple of ways todetermine if a reaction is exothermic or endothermic. Endothermic meaning that heat is added to the reaction to make the reactants interact and exothermic meaning heat is released during the reaction between the two reactants.

In endothermic reactions you can find a triangle above the arrow.
