○Law of Constant Composition- Compound always has the samecomposition. Therefore, a compound always has the same properties●Atoms are not created or destroyed in chemical reactions. A chemical reaction changes the way the atoms are grouped together. ○Law of Conservation of Mass- matter can neither be created nordestroyed. The total mass of matter at the end of the experiment isexactly the same as that at the beginning.Atoms●Atom- smallest unit of matter, made of smaller subatomic particles particles(protons, neutrons, and electrons)○Atoms is derived from a Greek word that means “cannot be divided”○Nucleus- the center of an atom, formed by protons and neutrons,electrons surround the nucleus (orbit)●Protons- positively charged particles●Neutrons- electrically neutral particles, which means they have no charge●Electrons- negatively charged particles with almost no massAtomic Mass Unit (amu)A unit of the scale relative masses of atoms●Mass Number (A)- the number of protons + number of neutrons in thenucleus of an atom.
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.
