In chemistry the focus is often on the individual molecule its structure, name, physical properties and chemical reactivity. Molecules do not generally exist isolated and alone, however. They are immersed in the environment around them, surrounded by other molecules which may or may not be...

With millions of chemicals to choose from, the number of chemical reactions that can be carried out is without limit. Faced with such possibilities, dealing with chemical equations can seem daunting. Matters are greatly simplified once you realize that there are a few basic types...
Exploring the ozone layer
By: Joanne
The Ozone LayerThe Ozone Layer lies in the Stratosphere, between approximately 10 and 50 kilometres above the Earth's surface. There it is invisible, but is very important nonetheless. It protects us by absorbing ultraviolet rays of the sun, therefore allowing us to inhabit Earth. Ozone...

The ideal gas law is familiar to many beginning chemistry students as "piv-nert" - the equation PV = nRT. In this equation, P stands for pressure, V for volume, n for the moles of gas, R is the gas constant, and T is temperature (in...

We know of LSD as an illegal drug which used for recreational purposes. It is known to produce psychedelic effects similar to intoxication. However it is interesting to note that the drug was initially developed to be used as a therapeutic agent. It showed great...
Exploring the ozone layer

Research The temperature of an object can essentially be described as the sensation of warmth or coldness felt with contact. However, this is only on a physical scale, as temperature is truly the measure of energy of thermal molecular motion. Once temperature reaches an absolute...

By definition, water has a neutral pH, 7.0, which is neither acidic nor basic (alkaline). To make an alkaline solution in water is easy. All it takes is the addition of a base. Even a small amount will do, as any pH above 7...
