Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

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...

Chain Reaction
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
Octet Rule
Many representative elements attain at least a share of eight electrons in their valence shells when they form molecular or ionic compounds, there are some limitations.
Saturated Solution
Solution in which no more solute will dissolve.
Solute
The dispersed (dissolved) phase of a solution.
xylene
Any of three oily, colorless, water-insoluble, flammable, toxic, isomeric liquids, C8H10, of the benzene series, obtained mostly from coal tar: used chiefly in the manufacture of dyes.
Nuclear Fission
The process in which a heavy nucleus splits into nuclei of intermediate masses and one or more protons are emitted.
Primary Standard
A substance of a known high degree of purity that undergoes one invariable reaction with the other reactant of interest.
Dipole-dipole Interactions
Attractive interactions between polar molecules, that is, between molecules with permanent dipoles.
Molecular Orbital Theory
A theory of chemical bonding based upon the postulated existence of molecular orbitals.
Explosive limits
The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.
