Science: Solutions, Compunds, And Mixtures

Front 1

pure substance

Back 1

matter that has a fixed composition and distinct properties

Front 2

elements

Back 2

a substance that cannot be separated into simpler substances by chemical means

Front 3

compound

Back 3

substances composed of two or more elements

Front 4

mixtures

Back 4

combinations of two or more substances in which each substance retains its own chemical identity

Front 5

solutions

Back 5

a mixture of substances that has a uniform composition; a homogeneous mixture

Front 6

solid

Back 6

matter that has both a definite shape and a definite volume

Front 7

liquid

Back 7

matter that has a distinct volume but not a specific shape

Front 8

gas

Back 8

matter that has no fixed volume or shape; it conforms to the volume/shape of its container

Front 9

reaction

Back 9

when a chemical structure changes

Front 10

dissolves

Back 10

when a solid turns into a liquid

Front 11

homogeneous

Back 11

when groups of molecules are evenly distributed

Front 12

solute

Back 12

the substance to be dissolved

Front 13

solvent

Back 13

the substance doing the dissolving

Front 14

solubility

Back 14

the amount of solute that can be dissolved by the solvent

Front 15

alloys

Back 15

mixture of two or metals

Front 16

heterogeneous

Back 16

when the groups of molecules aren't evenly distributed

suspensions

Back 19

heterogeneous fluid mixtures containing solids

Front 20

colloids

Back 20

heterogeneous fluid mixtures microscopically evenly dispersed throughout another substance

Front 21

molecule

Back 21

smallest part of a compound whose properties are those of the compound

Front 22

ionic/electrovalent bonds

Back 22

electrons are donated from one atom to another

Front 23

structure

Back 23

the structure of the substance = how easy it dissolves

Front 24

non-reactive

Back 24

a compound that has few or none of traits of the original compound of the original element of the new compound is not reactive

Front 25

states of matter

Back 25

solid, liquid, and gas

Front 26

covalent bond

Back 26

atoms share the electrons

Front 27

physical forces

Back 27

power, violence, or pressure directed against an individual consisting in a physical act
