Acid Rain
Acid rain occurs when of sulfur dioxide (SO2) and nitrogen oxides (NOx) are emitted into the atmosphere. They then go through chemical transformations and are absorbed by water droplets in clouds. Acid rain is a term referring to a mixture of wet and dry deposition from the atmosphere containing abnormal amounts of nitric and sulfuric acids. Acid rain is cause by volcanoes and decaying vegetation, but emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)

An In Depth Look At The Versatility Of Diels-Alder Reactions
An In Depth Look at the Versatility of Diels-Alder Reactions Introduction. It all started in the 1920's, when a pair of skillful chemists discovered what would become one of the most useful experiments ever performed. The name of this fascinating discovery is the Diels-Alder reaction. This reaction was named after two chemists, Paul Otto Diels, and Kurt Alder. Diels was a German organic chemist who invented a dehydrogenation process involving selenium. His most important work

The Color Rendition Index
The color rendition index, is a measure of the ability of a light source to reproduce the colors of various objects being lit by the source. It is a method devised by the International Commission on Illumination. The best possible rendition of colors is specified by a color rendition index of one hundred, while the very poorest rendition is specified by a color rendition index of zero. For a source like a low pressure sodium

Disintegration Of Uranium By Neutrons: A New Type Of Nuclear Reaction
On bombarding uranium with neutrons, Fermi and collaborators1 found that at least four radioactive substances were produced, to two of which atomic numbers larger than 92 were ascribed. Further investigations2 demonstrated the existence of at least nine radioactive periods, six of which were assigned to elements beyond uranium, and nuclear isomerism had to be assumed in order to account for their chemical behavior together with their genetic relations. In making chemical assignments, it was always
