== Definitions ==
* Chemistry
- Study of the compostion, structure, properties and reactions of matter
* [[matter|Matter]]
- Any material that occupies space and has mass
* Composition
- Identity and relative amounts of the components of matter. Described with
"formulas"
* Macroscopic
- Large scale properties that may be determined directly
* Microscopic
- Small scale properties that must be determined by indirect methods. Usually
on the atomic or molecular level
== [[energy|Energy]] ==
Ability to do work
see [[energy]]
== Scientific Method ==
Way to thourghly understand the world that is testable
== Accuracy vs Precision ==
* Accuracy
- agreement of measured values with the "correct" values
* Precision
- how reproducable is the measurment
== Error ==
* Systematic
- Error is higher/lower than expectation, usually due to measurment device
* Random error
- Always present, makes values change slightly
