AIR POLLUTION CONTROL IN INDIA Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The first law against air pollution was passed in 1873. Air pollution can …
Introduction Staining is a technique that is used to diagnose or study the morphology of abnormal cells such as cancerous cells by highlighting the structural components of a tissue (Bancroft and Gamble, 2008). Staining provides a contrast between different structures in a tissue specimen and …
Experiment 2: Isolation of Eugenol from Cloves Background; Readings on Vapor pressure, Raoult’s Law from TRO: A mixture of the essential oils, eugenol and acetyleugenol, will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution …

Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
