Le Chatelier's Principle

Front

States that if a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress.

Back

Metals

Front

Hard and shiny elements that are good conductors of heat and electricity that tend to lose electrons

Back

Matter

Front

Anything that has mass and takes up space

Back

Inorganic chemistry

Front

The study of substances that, in general, do not contain carbon

Back

Neutralization

Front

A reaction between an acid and a base

Back

Intrinsic

Front

Distinguish a substance by another substance, stands on its own

Back

Compound

Front

Substance formed when two or more elements are combined chemically

Back

Oxidation number

Front

Positive or negative number that indicates how many electrons an atom has gained, lost, or shared to become stable

Back

Indicators

Front

Substances that show different color changes to different color substances

Back

Physical change

Front

Change of physical properties in a substance

Back

Volume

Front

The amount of space an object takes up

Back

Metaloids

Front

Borderline elements between metals and nonmetals. Are semiconductors of heat and energy.

Back

Law of Multiple Proportions

Front

Two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

Back

Heat of reaction

Front

The quantity of energy released or absorbed as heat during a chemical reaction

Back

Law of Conservation of Mass

Front

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

Back

Biochemistry

Front

Chemistry dealing with chemical compounds and processes in living plants and animals

Back

Exothermic reaction

Front

A reaction that RELEASES energy in the form of heat

Back

Law of Definite Composition

Front

Chemical compounds are composed of a fixed ratio of elements as determined by mass.

Back

Heterogenous mixture

Front

Mixtures having parts with dissimilar properties

Back

Extrinsic

Front

Properties that depend on amount of matter observed

Back

Endothermic reaction

Front

A reaction that ABSORBS energy in the form of heat

Back

Amphiportic

Front

Can be either proton donors or acceptors. Can be considered as either acid or base.

Back

Tritation

Front

procedure used to quantitively mix acids and bases

Back

Chemical change

Front

Identity of the substance is altered

Back

Mass

Front

The amount of matter in an object

Back

Pure substance

Front

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

Back

Reaction mechanism

Front

Series of steps involved in a chemical reaction

Back

Analytical chemistry

Front

Study of qualitative and and quantitive analysis of elements and compounds

Back

Mixtures

Front

Materials made up of two or more substances

Back

Front

Mixture with similar properties and composition. Can't be separated by ordinary chemical means.

Back

Salt

Front

Substance produced through neutralization

Back

Nonmetals

Front

Brittle elements that aren't good conductors of heat and energy
