Science Quiz- Mixtures


a combination of 2 or more substances that are chemically combined; are pure substances; can be separated physically, such as filtration and evaporation; components are elements, compounds, or both; keep their original properties; formed using any ratio o

3 type of mixtures

solutions, suspensions, colloids


a mixture that appears to be a single substance but is composed of 2 or more substances that get evenly distributed among each other; not just liquids, but can be solids or gases too; honegeneous; example: hot chocolate


the process of particles separating and spreading through a substance


the substance that dissolves


substance in which the solute is dissovled or the part doing the dissolving


when a substance can dissolve


when a substance cannot dissolve


amount of solute dissolved in a solvent

concentrated solution

has lots of solute

dilute solution

has less solute

saturated solution

has all the solute it can handle

3 ways to speed up the solubity of a solution

crush, heat, stir


Compose of parts or elements that are all of the same kind ; essentially alike ; don't scatter light, cannot be filtered


a mixture in which the particles of material are dispersed throughout a liquid or gas but are large enough that they eventually setlle out; particles do not dissolve, particles scatter light, particles can be separated with a filter(heterogeneous); exampl


a mixture in which particles are disposed throughout but are not heavy enough to settle out; particles spread throughout, particles do not settle out, particles scatter light; homogeneous; example: milk


a compound made artificially by chemical reactions; plastic

Law of Conservation of Matter

Matter is not created nor destroyed in any chemical or physical change

Chemical Reactions

process by which one or more substances undergoes change to produce one or more different substances.


a pure substance made up of 2 or more elements that are chemically combined; break down chemically; one particle equals molecule; are elements; lose their original properties; separated by chemical means; formed using a set mass ratio of components


simplest form of matter; consists of a single particle of matter


made up of 2 or more atoms joined together by a chemical reaction; the atoms may be all the same or different


A pure substance that cannot be broken down into anything simpler by physical or chemical means; each has a unique set of ohysical and chemical properties; classified as metals, nonmetals, or metalloids, based on their properties


the _______ of a solute is the amount of solute needed to make a saturated solution using a given amount of solvent at a certain temperature; the ability of a given substance(solute) to dissolve into a solvent


Consist of elements that are not of the same kind or nature ; not of same kind or type; can scatter light, can be filtered


elements that are shiny and are good conductor of thermal energy and electric current, malleable, and ductile


elements that are dull, and poor conductors of thermal energy and electric current


semiconductors, elements that have properties both metals and nonmetals, some shiny, some dull

pure substance

made up of a single element or a compound
