Introduction
Have you ever mixed vinegar and baking soda? It’s fun to watch, but did you know that the reaction between the two is actually a chemical reaction that produces gas and changes temperature, too? The gas it produces is carbon dioxide, CO2, and the temperature changes. Does the temperature go up or down? We will soon find out!
