Chemistry Definition: Study of the structure and properties of matter and energy and how they react and how it can be applied

FIELDS OF CHEMISTY Biochemical Processes of the Living Physical Behavior &Changes of matter and energy Analytical Components and Contents of Substances Biochemical Processes of the Living Organic Chemicals With Carbon Inorganic Chemicals W/O Carbon Nuclear Reactions of the Atom’s Nucleus

MATTER Definition: ANYTHING THAT HAS MASS AND TAKES UP SPACE (Volume) CONTAINS THE PROPERTY OF INERTIA INTERTIA – Newton’s 1st Law of Motion - An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an outside force

ENERGY: The Ability to Do Work Types of Energy: Kinetic Energy of Motion Dependent on mass and speed of object EX: Potential Energy “at rest” Dependent on mass and position of object EX:

Other Types of Energy Light (electromagnetic) Thermal (heat) Electrical (electricity) Nuclear Chemical Gravitational

RULES OF CHEMISTRY ASSUMPTION The Universe is A Closed System therefore amount of matter must stay the same amount of energy must stay the same

Laws of Conservation Two Laws (but really just one): 1) Law of Conservation of Mass - matter can not be created or destroyed - it only changes form EX: 2) Law of Conservation of Energy - energy can not be created or destroyed - it only changes form Law of conservation of mass-energy: mass and energy are essentially one and the same - change into one another, but the total remains constant
