SSC MCQ Question Ans. Acid-Base Balance. Lead is extracted from the acidic residue of rejected batteries of vehicles /IPS/ solar panel in 50 furnaces on the beach of river Jamuna at Bera Upazila of Pabna district. People are extremely annoyed at the toxic smoke and bad odor from the furnaces. Crops are not growing in the lands near the furnaces. Cattles are dying by eating grass. Poor laborers bring out the toxic materials by breaking batteries with bare hands. Their hands are infected.

There are lead (Pb,) lead oxide (PbO2) and dilute sulphuric acid (H2SO4) in the two chambers inside the plastic cover of the battery. When heat is applied to the residue and the ash of the battery sulfuric acid decomposes and produces sulfur trioxide (SO3) and sulfur dioxide (SO2). Mixing of these two gases creates dense foggy like situation.

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.
