Description about Resonance

When a single structural formula of a compound could not satisfactorily explain all the properties of the molecule then two or more hypothetical structure (arrived by redistribution of valence electrons) may be drawn and each of which separately accounts mass of its properties. These structures are called resonating structures or canonical structures. The resonance hybrid […]

Microscope Basics

Anton Von Leeuwenhoek (1632-1723) was the Inventor of Microscope.Microscopes are the most indispensable instrument in a biology laboratory. They help to increase the resolving power of human which fails to recognize objects lying closer between 0.01 to 0.25mm. Some common types of microscopes are -Light Microscope: These Microscopes use light rays to illuminate objects. Dissection& […]

Eutrophication

Eutrophication is a natural process, derived from the Greek word eutrophos meaning well nourished or enriched. This enrichment leads to other slow process referred to as natural aging of lakes. Eutrophication escalates rapidly, however when normally high amounts of nutrients from fertilizers, domestric and industrial wastes, urban drainage, detergents, animal wastes and sediments enter water […]
