CHM 109 Lecture Notes - Lecture 1: Ductility, Boiling Point, Lewis Structure
Document Summary
Chemistry is the study of matter and energy in chemical and physical changes. A. the definition of matter is anything that occupies space and has mass. B. macroscopic matter refers to things we can see. C. particulate matter is represented by different kinds of models : Space-filling, ball-and-stick, lewis dot diagrams, formulas, line- angle drawings microscopic matter refers to things visible through a microscope particulate matter refers to atoms and molecules this is 5 carbons in a chain. 2. 2 states of matter: 3 common states of matter : and are spread far apart place (least kinetic energy) C. physical changes merely alter the physical form of a substance without. Table sugar elements in a compound can only be separated by chemical means, but cannot be broken down substance even though more than one element is present to a new substance. 2 impure matter is also called a mixture because it contains substances which are not chemically bound to each other.
