Back

matter

Front

Anything that has mass and takes up space

Back

mixture

Front

A combination of two or more substances that are not chemically combined

Law of Conservation of Mass

Front

the law that states that mass cannot be created or destroyed in ordinary chemical and physical changes

Back

compound

Front

A pure substance made up of only one type of molecule

Back

reactivity

Front

does it react chemically with other substances?

Back

endothermic

Front

Heat energy is used up during a reaction so the surrounding area feels COLDER

Back

physical change

Front

When a substance changes in appearance, but NO NEW SUBSTANCES are created.

Back

ductility

Front

The ability to be pulled into thin wires

Back

exothermic

Front

Heat energy is given off during a reaction so the surrounding area feels WARMER

Back

proton

Front

A subatomic particle that has a positive charge and that is found in the nucleus of an atom

Back

coefficient

Front

A number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction.

Back

products

Front

the new substances that are formed by the chemical reaction

Back

atom

Front

the smallest particle of an element that still has the properties of that element

Back

chemical change

Front

A change in matter that produces one or more new substances with different properties

Back

reactants

Front

A starting material in a chemical reaction

Back

pure substance

Front

A substance made of only one kind of matter and having definite properties.

Back

neutron

Front

A subatomic particle that has no charge and that is found in the nucleus of an atom

Back

molecule

Front

A group of atoms bonded together

Back

subscript

Front

A number written slightly below and to the right of a chemical symbol that shows how many atoms of an element are in a compound.

Back

element

Front

A pure substance made of only one kind of atom

Back

mass

Front

the amount of matter in an object

Back

electron

Front

A subatomic particle that has a negative charge and is found around the nucleus of an atom

Back

precipitate

Front

A solid that forms from a solution during a chemical reaction.

Back

chemical property

Front

A characteristic that can ONLY be observed when one substance is chemically changed into a new substance(s).

Back

physical property

Front

characteristic of a substance that can be observed or measured without changing the identity of the substance

Back

weight

Front

A measure of the force of gravity on an object

Back

characteristic property

Front

A quality of a substance that never changes and can be used to identify the substance

Back

malleability

Front

The ability of a substance to be hammered or rolled into sheets

Back

viscosity

Front

A liquid's resistance to flowing, thickness of a liquid

Back
