1. Exothermic vs. Endothermic Reactions

2. Exothermic Accompanied by the release of heat
Formed from its constituent elements with a net release of heat.
The energy released as the product is formed is greater than the energy required to break the bond in the reactions

3. Exothermic formula d

4. Facts about Exothermic
Occurs in everyday situations and nature.
Energy or heat is released.
when water condenses from a gas to a liquid or when liquid water freezes, the reaction is exothermic.

5. Examples of Exothermic
Liquid water freezing to form ice
Water vapor (raindrops)
Oxidation of metal forming rust.
Explosions from weapons or engines.

6. Endothermic
Formed from its constituent elements with a net release of heat.
Energy is required to break the bonds in the reactants then is released by the formation of the product

7. Endothermic Formula

8. Facts about Endothermic
Energy or heat is absorbed.
the reacting system takes energy from its surroundings to produce a reaction.
The products of an endothermic reaction have more heat than the reactants.

9. Examples of Endothermic
Ice cubes melting into liquid.
Water evaporating and becoming water vapor.
Cake baking in oven.

10. Endothermic/Exothermic Similarities
There both reactions involving a redistribution of energy
* they both have to do with energy and with bonds between atoms
