A characteristic of a substance that can be observed or measured.

A change in the form or appearance of a substance, but not its chemical composition (e.g., melting ice).

A system where only energy can be exchanged with the surroundings, but not matter (e.g., a sealed bottle of soda).

A system where both matter and energy can be exchanged with the surroundings (e.g., an open beaker of boiling water).

A state of matter with no definite shape and no definite volume.

A state of matter with definite volume but no definite shape.

A state of matter with a definite shape and definite volume.

Law of Conservation of Mass

The principle that states that matter is not created or destroyed during a chemical reaction. The total mass of the reactants equals the total mass of the products.

The large number written in front of a chemical formula in an equation (e.g., the '2' in 2H2O), indicating the number of molecules or moles of that substance.

The small number written below and to the right of a chemical symbol in a formula (e.g., the '2' in H2O), indicating the number of atoms of that element in the molecule.

A solid that is formed and separates from a liquid solution during a chemical reaction.

The substance(s) formed as a result of a chemical reaction, shown on the right side of a chemical equation.

The starting substance(s) in a chemical reaction, shown on the left side of a chemical equation.

A process that changes one set of chemicals into a new set of chemicals with different properties (e.g., burning wood, rusting metal).

A combination of two or more substances that are physically mixed but not chemically combined (e.g., salt and pepper).

A substance made up of two or more different elements chemically combined in a fixed ratio (e.g., water, salt).

A group of two or more atoms held together by chemical bonds (e.g., O2 or H2O).

A pure substance made up of only one type of atom (e.g., Oxygen, Gold).

The smallest unit of an element that retains the chemical properties of that element; the basic building block of matter.

Anything that has mass and takes up space (volume).

The branch of science that studies the composition, properties, and reactions of matter.

Anything that has mass and takes up space (volume).

The smallest unit of an element that retains the chemical properties of that element; the basic building block of matter.

A pure substance made up of only one type of atom (e.g., Oxygen, Gold).
