Chemistry, as the branch of science dealing with the study and analysis of the composition of natural substances is a very crucial subject which the society would not do without in everyday life. From the moment an individual is born, chemical substances or their combinations are used to preserve life and aid in life development.
Every day I wake up but before commencing on my daily routine I have to ensure my hygiene and personal cleanliness. I take a bath using soap manufactured because of chemical knowledge of substances like cetyl alcohol, glycerine and propylene compounds. Without chemistry, the sole existence of these substances or their effects would not be known. The society depends on the knowledge of chemistry for the availability of items we cannot do without on a daily basis. Things like beauty products, soaps, toothpaste, medicines, manufactured foodstuffs and electric batteries that run our watches, calculators, television and other remote controllers as well as advanced health accessories like artificial pacemakers and hearing aids (Myers, 2003).
Alcohols, ethers, carboxylic and many other organic chemical compounds whose functional group contain carbon and oxygen also find extensive use in everyday life. The foods we eat containing starches, sugars vitamins and proteins exist because of the knowledge of organic chemistry. Fuel substances ranging from firewood and charcoal, petroleum products for home use, automobiles and industry are also a part of organic chemistry. The pharmaceutical industry, forever ensuring our protection from germs, infections and diseases is purely based on chemistry. As a matter of fact, the society cannot do without chemistry, life would be so unsystematic.
To benefit from chemistry, exactness is necessary depending on the scale and nature of chemical substances being measured. There are two categories of measurement accuracy and precision. Accuracy measurements are done nearest to the intended target because achieving the exact target would not be possible or would be too unnecessarily tedious under the circumstances. For example in the mixing of small quantities of liquid chemical substances, it would virtually be impossible to achieve measurements to the exact milliliter as some of it would still remain in the measurement apparatus (Myers, 2003).
Precision measurements are repeatable because reaching a distinct value is possible and can be repeated again and again. Precision measurements are so because they are described in terms of units, like length, weight and so on. However, the level of precision reached depends on the sensitivity of the measuring equipment used. If, for example a ruler puts the length of a steel rod at 7.91 centimeters, a more exact instrument would put it at 7.899 centimeters.
The society depends on all these measurements in the provision of their everyday supplies like gasoline, soft drinks, personal care accessories like soap and so many others. If an individual is buying a kilogram of beef, it is, according to the standards of the trade, to get exactly one thousand grams. It is therefore understandable to carry home the nearest value acceptable as a kilogram of beef. On the other hand, pharmaceutical products need more exactness in the balancing of their composition. A buyer of, say tablets of aspirin, will expect that the composition was done to a repeatable exact measurement so that it does not bring about undesirable side effects (Moore, Lngley, 2008). In everyday life, I depend on accuracy while filling my gasoline tank at the service station and precision while buying my medical provisions. In the measurement of liquid substances like drinking water, coffee and tea and some basic quantities like the amount of sugar to put in a teacup or the weight of salt to put in one serving are all measures of accuracy.
