What is Chemistry? :What is Chemistry? Chemistry is the study of the composition of “matter” – (matter is anything with mass and occupies space), its properties, and the changes it undergoes.
Has a definite affect on everyday life - taste of foods, grades of gasoline, etc.
Living and nonliving things are made of matter.
Slide 2:Chemistry is the study of the composition, structure, and properties of matter and the changes it undergoes – such as burning fuels. C2H5OH + 3 O2 2 CO2 + 3 H2O + Energy Reactants Products
5 Major Areas of Chemistry :5 Major Areas of Chemistry Analytical Chemistry- concerned with the composition of substances.
Inorganic Chemistry- primarily deals with substances without carbon
Organic Chemistry- essentially all substances containing carbon
Biochemistry- Chemistry of living things
Physical Chemistry- describes the behavior of chemicals (ex. stretching); involves lots of math!
Boundaries not firm – they overlap and interact
What is Chemistry? :What is Chemistry? Pure chemistry- gathers knowledge for the sake of knowledge
Applied Chemistry- is using chemistry to attain certain goals, in fields like medicine, agriculture, and manufacturing – leads to an application (example - Aspirin – helps to relieve pain)
