What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

Emission Spectrum
Spectrum associated with emission of electromagnetic radiation by atoms (or other species) resulting from electronic transitions from higher to lower energy states.
Ostwald Process
A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
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.
Free Energy Change
The indicator of spontaneity of a process at constnt T and P. If delta-G is negative, the process is spontaneous.
Equilibrium Constant
A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
Explosive
A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.
Unsaturated Hydrocarbons
Hydrocarbons that contain double or triple carbon-carbon bonds.
Neutron
A neutral subatomic particle having a mass of 1.0087 amu.
Law of Conservation of Energy
Energy cannot be created or destroyed, it may be changed from one form to another.
Spectator Ions
Ions in a solution that do not participate in a chemical reaction.
