Chemical Reaction Lab Report

Mass is anything that takes up space. Mass is made up of small subatomic particles called atoms. Atoms have three main parts electrons, protons, and neutrons. The mass of the atom is found in the nucleus. The Law of Conservation of Mass states that mass cannot be created nor destroyed, and that the mass of the reactants will be equal to the mass of the products. This means that no matter what, the mass of the reactants when mixed together should be equal to their original masses. A chemical reaction changes one or more substances to be transformed into (a) new substance(s). A physical change is the change in somethings appearance. Chemical changes can be identified by its interaction with other substances. How does the mass of the substances

The materials for the lab included: Sodium bicarbonate, acetic acid, large Erlenmeyer flask, balloon, small graduated cylinder, and an electric balance. The second step of the first experiment was to measure 10 mL of acetic acid in the graduated cylinder. Next, measure half a spoonful of sodium bicarbonate. To weigh the sodium bicarbonate it was placed in the flask and weighed, using the electronic balance. The weight of the sodium bicarbonate was recorded in a data table. After the sodium bicarbonate was weighed the acetic acid(inside the graduated cylinder) was weighed on the electric balance. The weight of the acetic acid was recorded in a data table as well. The acetic acid was then poured into the flask with the sodium bicarbonate. The balloon was used to quickly cover the opening of the flask, in order to prevent the gas from leaking. The product was weighed and compared to the weight of the

This claim was made because it was backed up by our first experiment. Our first experiment showed that the products and the mass have the same mass. The four bars on the graph show the masses of the reactants and products of two experiments. In experiment 1 the mass of the reactants and products are very close to each other. The reactants have a larger mass because they had not created any gases that could escape. The graph proves the Law of Conservation of mass. The similar masses show that with less errors the experiment the products mass and the reactants mass will be equal. This investigation is tied into the Law of Conservation of Mass. The Law of Conservation of mass cannot be created or destroyed. This shows that after a chemical reaction none of the mass from the reactants can be destroyed and no more mass can be created. This evidence proves the Law of Conservation of
