Le Chatelier's Principle

States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it.
If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.

Critical Pressure

The pressure required to liquefy a gas (vapor) at its critical temperature.

Turning iron nail into copper nail

This simple chemical experiment shows the so-called process of copper plating of metal products. Copper has the ability to deposit on a metal surface.

Chemical Bonds

The attractive forces that hold atoms together in elements or compounds.

Absolute Entropy (of a substance)

The increase in the entropy of a substance as it goes from a perfectly ordered crystalline form at 0 °K (where its entropy is zero) to the temperature in question.

Entropy is a measure of the “dilution” of thermal energy.

Matter

Anything that has mass and occupies space.

Safranine

Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.

Formula Weight

The mass of one formula unit of a substance in atomic mass units.

 

Reaction Stoichiometry

Description of the quantitative relationships among substances as they participate in chemical reactions.

Liquid Aerosol

Colloidal suspension of liquid in gas.
