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)
