Compounds & Mixtures
A substance that is formed when two or more atoms chemically join together
What is a molecule?
A homogenous mixture of two or more substances
(In other words, the name of the substance where something is dissolved into a liquid)
What is a solution?
A method of separating the substances in a mixture by the rate they move through or along a medium, such as filter paper
What is Chromatography?
A compound that conducts electricity in a solution
What is an electrolyte?
The chemical symbol for Zirconium
What is Zr?
A combination of two or more elements or compounds that are NOT chemically combined
What is a mixture?
The substance in which the solute dissolves to form a solution, typically a liquid. (Water is considered the universal________ )
What is a solvent?
A method of separating a liquid from a solid by passing the mixture through a filter that allows liquid to pass, but not the solids
What is filtration?
A piece of metal or graphite that allows the electrical current to flow into the electrolyte
What is an electrode?
The chemical symbol for Silver
What is Ag?
This means that a substance has all the same particles in the same phase. Examples of this type of mixture include air, steel, and rainwater.
What is homogenous?
The substance that dissolves in the solvent (liquid) to form a solution.
What is a solute?
forensic science (analyzing crime scenes), food safety testing, air and water quality testing, drug testing, and blood testing

The method used to separate water into its components of hydrogen and oxygen
What is electrolysis?
The chemical symbol for Tin
What is Sn?
A word to describe liquids that can be blended together
What is miscible?
Describes a mixture in which the particles are in different phases. Examples include pepperoni pizza, vegetable soup, cereal in milk, blood, soil, mixed nuts, and ice in soda.
What is heterogenous?
This molecule has two hydrogen atoms and one oxygen atom
What is water? (or H-2-O)

What is the Law of Constant Composition?
Describing a molecule that has a positive and a negative end.
