Handwritten notes from a High School chemistry class throughout the whole year. These notes cover the basics of chemistry from basic measurements to balancing equations. These notes were taken in conjunction with the textbook "General Chemistry" by John D. Mays. Chapters 1-3, 5, 6, 9, and 11 are covered. Chapter 1: basic measurements and units Chapter 2: atoms and substances, Avogadro's constant, and molar mass Chapter 3: atomic structure Chapter 5: ionic vs covalent bonds, the octe...
