1.1 Chemistry Summary:
Chemistry is the study of the composition and properties of matter and how they
change. Matter is anything that has mass and occupies space. Since living and
nonliving things are made of matter, chemistry has an impact on life and most natural
events. It can explain how you emulsify fatty substance on your skin and hair with
chemically treated water and formulated detergents in a shower. There are five areas
of study in chemistry. They are organic chemistry, inorganic chemistry,
biochemistry, analytical chemistry, and physical chemistry. Organic chemistry is the
study of all chemicals containing carbon. In contrast, inorganic chemistry is the study
of chemical that do not contain carbon. Biochemists study processes that take place
in organisms such as muscle contraction and digestion. The study that focuses on the
composition of matter is analytical chemistry. One example of this study is
measuring the level of lead in drinking water. Physical chemistry is the study that
deals with the mechanism, the rate, and the energy transfer that occurs in chemical
reactions. Pure and applied chemistry are two approaches in learning chemistry.
Pure chemistry is the pursuit of chemical knowledge for its own sake. On the other
hand, applied chemistry is research that is directed toward a practical goal or
application. Pure research can lead directly to an application, but an application can
exist before research is done to explain how it works. We learn chemistry to explain
the natural world, prepare for career opportunities, and become an informed citizen.
