Introduction: In Stoichiometry, you can figure out how much product is produced from a chemical reaction by using the starting amount of a substance, while using math. Stoichiometry is the study of the relationships or ratios between two or more substances undergoing a physical or chemical change (Helmenstine). Since all reactions are dependent on how much was started with, we use those numbers to get the product number. In a limiting reactant problem, an amount is given for both the reactants. The smaller amount will ‘limit” how much the reactant can produce. A percent yield in a chemical equation is used because chemical reactions do not predict amount of a substance. The percent yield is usually determined by the mass that is in the chemical reaction. A percentage will be produced from using the formula; This percentage is the calculation of your success of producing a product compared to the total amount of a product that can be produced. The familiar volcano experiment that we all know, mixing baking soda and vinegar, is used to create a bubbly reaction. In the lab, two substances are mixed and create sodium acetate, carbon dioxide, and water (CH3COOH). The purpose of the lab was to predict how much product was made from the chemical reaction, using stoichiometry. If there is a certain amount of baking soda, mixed with 50 mL of vinegar, then the percent yield will be able to be predicted. The percent yield gained was calculated from the amount that was recovered from the experiment. The hypothesis created from this experiment was if a certain amount of baking soda, mixed with 50 mL of vinegar, then the percent yield will be able to be predicted. Materials/Methods: The materials needed to carry out this experiment were, baking soda and vinegar (acetic acid). Two beakers were needed. Also, a Bunsen burner with a wire
