A reaction that gives out energy to its surroundings.
What is an Endothermic reaction?
A reaction that absorbs heat from its surroundings.
This is a diagram that shows an Endothermic reaction:
This is a diagram that shows an Exothermic reaction:
Dissolving salts can be exothermic or an endothermic reaction.
a neutralisation reaction is an exothermic reaction.
A displacement reaction is an exothermic reaction as the reactions release energy.
Precipitation reactions are exothermic.
Breaking bonds is endothermic while forming bonds is exothermic as they require energy to form them.
To calculate the bond energy, you must add every single bond on the left side. And do the same thing on the right side. Subtract the left side from the right side. If it's negative, then it's exothermic. IF it's positive, then it's endothermic.
