CHM 2045 Lecture Notes - Lecture 1: List Of Compositions By Carl Philipp Emanuel Bach, Chemical Formula, 3Mv
Document Summary
Chemistry: chemistry is the science of matter by examining the behavior of atoms and molecules, it"s the building blocks of the physical world. Observation, law, and theory: an observation is what a scientist sees. Ex: phosphorus burns bright white: a scienti c law is a brief statement that summarizes past observations and predicts future ones. Ex: in chemical reactions, matter is neither created nor destroyed: a scienti c theory allows you to predict behavior and describe the underlying cause of physical behavior. Ex: all matter is made of tiny, indestructible particles called atoms. Matter: matter is anything that occupies space and mass, which can be classi ed by state and by composition, there are three phases/states of matter: 1) solid: xed shape and volume; incompressible: liquid: has variable shape with a xed volume and is incompressible, gas: has variable shape with variable volume and is compressible.
