My science fair project is based on a chemical reaction taking place to turn a hot substance into ice. A chemical reaction is a reaction that changes the substances original identity to a different chemical identity. There are many different types chemical reactions in chemistry, but the one we are going to be focusing on are exothermic reactions. Exothermic reactions are reactions that transfer energy to the surroundings.

The exothermic reaction is a reaction that gives off more energy than it needs to in order to complete its reaction. The exothermic reaction in this project is between baking soda and vinegar. Baking soda is a bicarbonate and vinegar is a acetic acid. Baking soda is made up of 1 sodium, 1 hydrogen, 1carbon, and 3 oxygen atoms. Vinegar is composed of 2 carbon, 4 hydrogen, and 2 oxygen atoms. Baking soda is an alkaline object that is alike to some salt and it reacts to acidic substances. When baking soda reacts it gives off some type of gas, carbon dioxide. Baking soda is usually seen in cooking, cleaning substances around the house, and in may science projects due to its ability to react with acids. Baking soda is usually used to …show more content…
This acid is known as a decomposition reaction due to its different properties. Carbonic acid is an unstable acid that breaks apart when it is placed in carbon dioxide and water. The carbonic reaction weighs more that air and this causes it to fall out of the container looking like water when it overflows. It is also a type of gas that leaves our body when we breath out. We create small amounts of this in our body because of the reactions that go through the inside of our body. Carbonic acid is a very important part of this project because it is the substance or mixture that causes the exothermic reaction. This is what Carbonic acid does and how it is created in the mixture of the vinegar and of the baking
