we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the color of the

Mass relationships in a chemical reaction Introduction: The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words‚ the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction‚ the total mass will be the same at any point in time in any closed system. http://www.nature
