__Explanation:__ __Why do Vinegar and Baking Soda react in a Fizz?__

The experiment of Baking Soda and Vinegar is one of the most popular experiments in the world, yet, it is a very simple process. What appears to be one result, is actually two results. This is called a Multi-Step Reaction. The Acetic Acid (What makes Vinegar sour) reacts with Sodium Bicarbonate (a compound thats in Baking Soda) to make Carbonic Acid, this is called a Double Replacement reaction. Carbonic Acid is not stable, and it will immediately fall apart into Carbon Dioxide and water, otherwise known as a decomposition reaction. All of the bubbles that appear from the reaction are made because the Carbon Dioxide is escaping from the solution that is left. Carbon Dioxide is heavier than air, so, it flows like water when it overflows out of the container. Carbon Dioxide is a gas that you exhale (but in little amounts), because it is a product that keeps your body moving, and functioning. Whats left is a dilute solution of sodium acetate in water. That is why Vinegar and Baking Soda react in a fizz!
