What is Chemistry?
 The
study of “matter”, its composition,
properties, and the changes it
undergoes.
 Applied Chemistry - uses chemistry
to attain certain goals, in fields like
medicine, agriculture, and
manufacturing
 Pure chemistry - gathers knowledge
for the sake of knowledge

5 Major Areas of Chemistry

Analytical Chemistry - concerned with the
composition of substances.
Inorganic Chemistry - deals with
substances without carbon
Organic Chemistry - deals with substances
containing carbon
Biochemistry - chemistry of living things

Physical Chemistry - deals with the
