Chemistry Chapter 1 Notes Chemistry - the study of material based on its matter (composition or structure) and behavior (properties).

Matter is anything that has inertia. • Inertia is the property of matter described as a resistance to change in motion. • Energy is the ability to do work. • Potential energy refers to the amount of stored energy. • Kinetic energy refers to the energy used for motion. • Radiant energy is the type energy emitted from electromagnetic waves

Law of Conservation of Mass • states the total amount of mass throughout the universe is constant.

Law of Conservation of Energy • states the total amount of energy throughout the universe is constant. • Both laws were believed to be true for over 200 years. Einstein set them straight.

E=mc 2 • Law of Conservation of Matter and Energy • ” state that together matter and energy is conserved. (Nuclear Rxns. )

Intermediates • are the in-between steps of a reaction. • They are not the raw materials nor the products.

Process or Scientific Method • involves different steps used for exploring and finding out about the unknown. • (Hypothesis, Observation and Experimentation) are the most common.

Models • are important in describing the behaviors and structures of chemicals and systems being studied.
