Objective: The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have

ABSTRACT OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be
