Law of Conservation of Mass: The total mass of substances present after a chemical reaction is the same as the total mass of substances before the reaction. 2. Law of Definite Proportions: All samples of a compound have the same composition-the same proportions by mass of the constituent elements. 3. Law of Multiple Proportions: If two elements form more than a single compound, the masses of one element combined with a fixed mass of the second are in the ratio of small whole numbers. 6.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
