Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth’s atmosphere and that of other planets is studied. Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It can be defined as the study of the sources‚ reactions‚ transport‚ effects‚ and fates of chemical species in the air‚ soil‚ and water environments; and the effect of human activity on these. Environmental chemistry is an interdisciplinary

Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. SELECTIVE PERMEABLE MEMBRANE=a membrane (as a cell membrane) that allows
