alcohol substance dependence

5) The permeability of the substance, that is, m r < 1. 6) The substance loses its magnetization as soon as the magnetizing field is removed. 7) Such specimen cannot be easily magnetized and so their susceptibility is negative. Example: Bismuth, antimony, copper, gold, quartz..

Alcohol consumption has grown as great pervaded addiction openly promoted by governments. No attempts are made by many state governments to curb alcoholism. On the contrary most governments are dependent on alcohol for their revenues. Hence, it can be called..

Monohydric alcohols are classified as primary, secondary or tertiary alcohols depending upon whether the hydroxyl group is attached to primary, secondary or tertiary carbon atom. For e.g., In 1 o alcohol, only one carbon atom is attached to the carbon carryin..

The liquid in which the substance is dissolved is termed as the mobile phase or eluent. The eluents employed are petroleum ether, carbon tetrachloride, benzene, alcohol etc. Their selection depends upon the relative solubilities of the components of the mixture in the..

is a homogeneous mixture of a solute dissolved in a solvent. Examples: Salt and water, sugar and water, iodine and alcohol. It should be remembered that: 1. A Solution is a homogeneous mixture of two or more substances. These substances can be in any of the three phy..

Lipids are organic substances present in all living organisms. They include fats, oils, waxes and other related compounds. They are insoluble in water and hydrophobic, and soluble in organic solvents. They are related to fatty acids and are not polymers. They are esters of long chain fatt..

Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced in solution. The beha..

Biotechnology is science of manufacturing useful substances, chemicals, medicines by use of living organisms and their life process. In fact, biotechnology is not a new science. Alcohol was the first product manufactured by ancient biotechnologis..

A liquid possesses a definite volume but not definite shape. The substances in liquids have particles, which are loosely packed and bound to each other by forces weaker than those of solids. This makes a liquid mobile and shapeless resulting in its taking up the shape of the container in..

Lipids - Lipids are organic substances present in all living organisms. They include fats, oils, waxes and other related compounds. They are insoluble in water and hydrophobic, and soluble in organic solvents. They are related to fatty acids and are not polymers. They are esters of long c..
