Heterogeneous mixture-

Back 10

Mixtures that don't have the same composition, properties, and appearance throughout mixture.

Front 11

Bonds-

Back 11

Atoms in a compound are chemically joined together by strong forces.

Front 12

Insoluble solid-

Back 12

A substance that does not dissolve

Front 13

Soluble solid-

Covalent bonds-

Back 16

When atoms share electrons

Front 17

Ionic bonds-

Electrons are donated from one atom to another

Front 18

Law of constant compositions-

Back 18

The observation that the elemental composition of pure compound

Front 19

States of matter-

Back 19

Solute

Back 21

The substance dissolves by a solvent in a solution

Front 22

Suspensions-

Back 22

Heterogeneous fluid containing solid particles large enough for sedimentation

Front 23

Liquid-

Back 23

Has a distinct volume independent of its container but has no specific shape

Has both definite shape and definite volume

Front 26

Chemical bonds-

Back 26

Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal

Front 27

Chemical substance-

Back 27

A substance is matter which has a specific composition and specific properties
