An Exothermic reaction releases heat during the reaction.

A nuclear explosion is an example of a high exothermic reaction. During the explosion, heat and energy are given off at extremely high rates.

An endothermic reaction consumes heat during a reaction.

While an egg cooks, it absorbs the heat in order to be ready to eat. This is an example of an endothermic reaction.

We know this is a chemical reaction because a new substance was formed in the fizz. The new  products are liquid water (H20), carbon dioxide gas (CO2), and solid table salt (NaCl).
