It is believed that the habit - is a form of human behavior. There are both positive habits and bad habits lead to useful personal development, and harmful, contrary to its destruction. It is important to know that the habit is a thing stiyka.Studentam particular care must be taken to ensure that there were close only positive habits. Useful habits can be hard, strive to learn new things and learn as much as possible, striving to exercise, the desire for cultural leisure, such as visiting the theater, reading knyh.Vsi these classes gradually enriching human knowledge, he becomes curious and starts to cultivate. But despite all this purity of the students there and bad habits. It whipped diet, irregular sleep and omissions in the classroom or homework. The most harmful habit is, of course, smoking and drinking alcoholic beverages. Habits can easily turn into a vice and ruin future life lyudyni.Likari reminded that the risk of cardiovascular diseases there is smoking. A harmful effect of cigarette provides nicotine. If suppose a young student smokes a cigarette its vessels dilate and thus he can feel that it improves performance, but not at dovho.Ale after which, the period of reduced mental capacity again and there again the need for a cigarette. Also for men Smoking is not very positive, because if you smoke for a long time, this leads to poor performance secretion. Increasingly, adrenaline is released into the blood, increases blood pressure, which leads to disruption of the heartbeat.

  it has already been explained that an ester is the product formed by the reversible reaction between an acid and alcohol. if an acid and an alcohol are mixed, a condition of equilibrium will eventually be set up when the rates of the direct reaction (etherification) and the reverse reaction (hydrolysis) are equal. it follows from the law of mass action that an increase in the molecular concentration of anyone of the reacting substances will displace the equilibrium in the opposite direction. any excess of water will diminish the proportion of ester present at equilibrium. consequently, in the preparation of esters, it is necessary as a rule to use the anhydrous acid and alcohol in order to obtain good yields, and the reaction is usually carried out in the presence of an acid catalyst (concentrated sulfuric acid or dry hydrogen chloride). an ester may be almost completely hydrolyzed if it is heated with water, provided that a large enough proportion of water is used. the hydrolysis is usually slow, but is catalyzed by acids. it becomes complete if a dilute solution of an alkali is used instead of water, for the acid produced by hydrolysis is neutralized by the alkali as fast as it is formed, and so can take no further part in the reaction. most esters of organic acids are pleasant-smelling, volatile liquids and many of them are used in perfumery and in the production of artificial flavoring agents. ethyl acetate is a typical example of an ester of an organic acid. it is formed when acetyl chloride or acetic anhydride acts on ethyl alcohol. ethyl acetate is prepared by the interaction of alcohol and glacial acid, in the presence of concentrated sulfuric acid.
