Chemistry Homework Help
Chemistry is a branch of science that involves the study of structure, composition, and properties of matter. It is a creative discipline mainly concerned with atomic and molecular structure and its change, for instance through chemical reactions.
Chemistry may define as the study of matter, its properties how and why substance combine or separate to form other substance and how substance interact with energy. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry can also define as physical science that helps us to describe and explain our world.
There are five branches of chemistry:-
(1) Analytical chemistry:-It includes the use of qualitative and quantitative observation to identify and measure the physical and chemical properties of substance.
(2) Physical chemistry :- It is the combination of chemistry with physics . How matter and energy interact is studied by physical chemists. There are two sub-branches of Physical chemistry:-
(b) Quantum mechanics
(3) Organic Chemistry:- Organic chemist studies compounds that contain the element carbon. Organic chemistry have a great influence in our life because all of the molecules that make up living tissues have carbon as a part of their makeup.
(4) Inorganic Chemistry :- In this branch of chemistry the chemists study materials such as metals and gases that do not have carbon as part of their makeup.
(5) Biochemistry :- It is the study of chemical processes that occur within living organisms.
Area or scope of chemistry:- The area or scope of chemistry is very vast and it influences our daily life. Chemistry improves many products, from the food we eat and the clothing we wear to the materials with which we build our homes. Chemistry helps us to protect our environment.
(a) Food chemistry
(b) Environmental chemistry
(c) Agriculture chemistry
(d) Chemical engineering
(f) Forensic Chemistry
