1. Identify the Problem
Exploring the other planets brings the chance of discovering undiscovered facts about space! This could
bring dramatic chances to how we live.
Though the exploration of spac
1.02: Chemistry and Society
Chemistry is part of our daily lives.
Examples: A glass bowl, a metal spoon, a tablecloth, a glass of milk, cereal, and a ceramic plate
Chemists determined the correct amounts of various vitamins, minerals, and preservatives to
Paper chromatography separates substances on the basis of how quickly the substances move
Chromatography uses mobile phases and stationary phases to separate mixtures. Take a look at how
paper chromatography does this.
1.01 Semester introduction
1. Chemistry-is the study of matter and the changes it undergoes.
2. Chemists have combined atoms in infinite variety to produce substances, such as
fabrics, fuels, medicines and plastics.
3. Chemistry involves the study of matt
1.03:Matter and Energy
Matter undergoes changes, with the help of energy.
Matter can undergo both chemical and physical changes.
Matter has mass and volume; energy is the ability to cause change.
Matter is the "stuff" of our world.
Example: pick up a cand

1.05: Pure Substances
Matter is made of mixtures and pure substances.
John Marshall discovered gold at Sutter's Mill. Many miners panned for gold.
The miner's pan contained a mixture of water, sediment, sand, gold, and other things.
A mixture is a physica
Scientists need to understand and separate mixtures.
If an athlete is being tested for use of a performance-enhancing drug, the athlete's blood is sent to a lab
where an analytical chemist performs various tests on the samples. Similar procedures are used
