SSC MCQ Question Ans.Chemistry in our life

SSC MCQ Question Ans.Chemistry in our life. Mango is a very popular fruit in Bangladesh. People are afraid of eating fruit because calcium carbide is used to ripen them or preservatives are used. People think there is formalin in fishes, where will they go? The elements used to ripen fruits and as preservatives are chemical substances.   All the chemicals used in our everyday requirement are not harmful. Every day we get up from bed with chemistry and go to bed finishing chemistry. Our foods, cosmetics, fertilizers-pesticides used to produce foods, cleaning materials etc. all are chemical substances.

SSC MCQ Question Ans.Chemistry in our life

Realizing the importance of chemistry in our life the 100th years of winning Nobel Prize in chemistry by Madam Marie Curie the international organization of chemistry and applied chemistry (IUPAC) celebrate the year  2011  as the year of chemistry.  The demonstrated theme was “Chemistry is our life and Chemistry is our future”.

The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism, and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.

Chemistry is a branch of science that involves the study of the composition, structure, and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions.

Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

The days are long past when one person could hope to have detailed knowledge of all areas of chemistry. Those pursuing their interests into specific areas of chemistry communicate with others who share the same interests. Over time a group of chemists with specialized research interests becomes the founding members of an area of specialization.

The areas of specialization that emerged early in the history of chemistry, such as organic, inorganic, physical, analytical, and industrial chemistry, along with biochemistry, remain of greatest general interest. There has been, however, much growth in the areas of polymer, environmental, and medicinal chemistry during the 20th century. Moreover, new specialties continue to appear, as, for example, pesticide, forensic, and computational chemistry.

This course provides students with the opportunity to develop their knowledge, understanding, and skills in relation to properties and structures of matter and a variety of chemical reactions incorporating organic compounds and acid/base equilibrium reactions.

Chemistry is one of the diverse branches of physical science. It is known as the science of life. The practice of chemistry has been in a constant increase since the ancient time. The present-day chemical industries have been evolved from the early practices of the Alchemists. Chemistry as a discipline encompasses a wide range of areas. It has always been devoted to the welfare of human and its environment.
