Attend lectures and keep notes.
Read your notes and a text book the same day
after class. Do your home assignment as soon as
you can.
Make surethat you understand material, don’t
accumulate unanswered questions. Please, don’t
be shy, ask; there is no such thing as a ‘stupid
question’

What is Chemistry?

Experiment and Explanation

Chemistry is the study of the composition,
structure, and properties of matter and energy
and changes that matter undergoes.
Matter is anything that occupies space and has
mass.

Energy is the “ability to do work.”

NMSUExperiment and explanation are the heart of
chemical research.
An experiment is an observation of natural phenomena
carried out in a controlled manner so that the results can be
duplicated and rational conclusions obtained. After a series
of experiments, a researcher may see some relationship or
regularity in the results.
If the regularity or relationship is fundamental and we can
stateit simply, we call it a law. A law is a concise statement
or mathematical equation about a fundamental relationship
or regularity of nature. An example is the law of
conservation of mass, which says that mass, or quantity
of matter, remains constant during any chemical change.

Experiment and Explanation
Explanations help us organize knowledge and
predict future events.
Ahypothesis is a tentative explanation of some regularity
of nature. If a hypothesis successfully passes many tests, it
becomes known as a theory.
A theory is a tested explanation of basic natural
phenomena.
