What is a Homogeneous Mixture?
Homogeneous - components are distributed uniformly throughout the sample and have no visible boundaries or regions
What is a Extensive Property?
A property that varies with the quantity of the substance present.
What is a Physical process?
Physical - a change in which a substance's physical appearance changes, but its chemical composition does not.
A property of a substance that can observed only by reacting it to form another substance.
What is a Anion?
Anions - negatively charged ions

What is a Mixture?
A combination of two or more pure substances
What is a Intensive Property?
A property that is independent of the amount of substance present.
What is a Cation?
Cation - positively charged ions
What is a Pure Substance?
Pure Substance - made up of only one type of particle (one component) and its composition does not vary.
What is an Atom?
The smallest particle of an element that retains the chemical characteristics of that element.
What is a chemical process?
A change in which a substance's chemical composition changes
What is a Element?
Element - a pure substance that cannot be separated into simpler substances by any chemical process
What is an Element?
The most basic units of matter. Unable to be broken down into smaller units through chemical means.
What is a Molecule?
An assembly of two or more atoms that are held together in a characteristics pattern by chemical bonds.
What are the three States of Matter?
Solids - Definite shape/volume
Liquids - Occupies definite Volume, but also flows to assume the shape of its container
Gases - Neither definite volume nor shape; expands to fill its container
What is a compound?
Compound - a pure substance composed of two or more different elements bonded together in fixed proportions
What is a physical property?
A property of a substance that can be observed without changing it into another substance.
What is a Heterogenous Mixture?
Heterogeneous - components are not distributed uniformly and may have distinct regions of different compositions.
