CH 110 Lecture Notes - Lecture 1: Atomic Orbital, Hourglass, Boiling Point
Document Summary
Chemistry is the study of properties and matter of life. An atom is the simplest form of matter. Contains neutrons (n- neutral) and protons (p- positive) M ol ec ul e- combination of two or more atoms in specific shapes. Having a uniform spatial composition in every direction. Can conform to the shape of the container. Does not depend on the amount of matter being examined. Doubling the amount matter does not change this property. Depends on the amount of matter being examined. Ex. mass, volume , # of particles, energy. Observed w/o changing the identity and composition of the substance. Describes how a substance may change or react to form another substance. Separates heterogeneous mixture where solid separates liquid- liquid homogeneous mixtures. Fraction dist: used to separate liquid-liquid when the boiling points are similar particles did not dissolve w/in the fluid.
