Match the project to the appropriate field of chemistry (inorganic chemistry,
BlackZzzverrR [31]

Chemistry is composed of many sub-disciplines such as inorganic chemistry, physical chemistry, biochemistry, organic chemistry, analytical chemistry etc. The following is a matching of certain projects against the sub-discipline in chemistry where they rightfully belong.

1) Determine the composition of a moon rock sample..... analytical chemistry

2) Do research on making a new medicine to treat high blood pressure..... biochemistry

3)  Investigate ways to regulate the rate of gasoline burning in an automobile engine......physical chemistry

4) Develop a plastic that can be decomposed by bacteria......organic chemistry

5) Improve the method for extracting iron from iron ore.....inorganic chemistry

The sub-disciplines of chemistry all work together to make the world a better place. The science of chemistry is very pivotal hence it is applicable in every area of science and technology.

Analytical chemistry, as the name implies, deals with "analyzing" or finding out the components of materials.

Biochemistry is concerned with the study of molecules that have biological activity such as medicine to treat high blood pressure.

One key area of physical chemistry is chemical kinetics which discusses rates of chemical reactions. This sub-discipline is important when investigate ways to regulate the rate of gasoline burning in an automobile engine.

Organic chemistry is the chemistry of carbon compounds. It studies compounds that contain long chains of carbon such as those found in plastics.

Inorganic chemistry deals with the study of the elements including the extraction of elements such as iron from its ore.
