Environmental Chemistry It often matters how much given atoms combine‚ in what arrangement‚ with what others‚ what impulse they receive‚ and what impart. The same ones make up earth‚ sky‚ sea‚ and streams; the same as the sun‚ the animals‚ grains and trees‚ but mingling and moving in every different ways. - Lucretius (95-52 B.C.) in The Nature of Things I. Physical Chemistry Why is Physical Chemistry important in the study of Environmental Engineering? • Applied physical chemistry procedures

Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double

Environmental Engineering Environmental engineering is a field related to direct application of science and engineering principles to the environment in which animals‚ humans and plants are living. An environmental engineer as a professional is concerned to protect the environment from deterioration; he is also concerned with the preservation of resources including plants‚ fuels‚ and fossils which can generate energy for human use. The primary task of an environmental engineer is to provide

removal based upon their structural class. The rhamnolipid biosurfactants enhanced the rate of linear alkane biodegradation more than the biodegradation rate of the monoaromatics. The rate constants for hexadecane and dodecane increased by 111 and 76% to 4.7 and 0.3 mg/h‚ respectively‚ while those of benzene and toluene increased by 34 and 65% to 3.1 and 4.0 mg/hr‚ respectively. The branched alkane degradation rate constants were also increased by 71% for iso-octane and 39% for pristane. In contrast

solubility Boiling points increase as intermolecular attractive forces increase. For the alkanes‚ which are non-polar hydrocarbons‚ the intermolecular forces are induced dipole forces. In the case of the alcohols‚ the intermolecular forces include induced dipole forces‚ dipole forces‚ and hydrogen bonding. Induced dipole forces increase with increasing molecular weight‚ so the boiling points of the straight chain alkanes increase as the number of carbon atoms in the chain increases. Therefore pentane

Alkanes‚ alkenes‚ alkynes and aromatic rings are the four classifications of hydrocarbons. Each of these classifications have different physical and chemical properties that were tested as this experiment was performed. Flammability test and solubility test

the type of bonding that exists between the carbons. There are hydrocarbons that contain only carbon-to-carbon single bonds and they are called alkanes. There are also hydrocarbons that contain only carbon-to-carbon single bonds but it is different from alkanes because their carbon atoms are bonded together to form rings. They are called cyclohexanes. Alkanes and cycloalkanes are also known as saturated molecules – containing only carbon-to-carbon single bonds. When we say that a hydrocarbon is saturated
