Chemistry -the Central Science

Chemistry: study of matter

(materials) and its transformations. CHEMISTRY

Materials

LifeSciences

Engineering

Physics

Math


Chemistry the molecular science Macroscale: what we can see (observe) Nanoscale: what is happening on the molecular level

How does the behavior of atoms and molecules connect to the behavior of matter that we observe?


Chemistry the molecular science

Why Study Chemistry?

• Connecting microscopic properties to macroscopic properties

•  Energy stored in molecules •  Learn the language of chemistry • How do we know what we know? (Modern Analytical

techniques and Instrumentation) • Develop analytical problem solving skills •  Structure Affects Function (Properties)

How to be successful

Keep your eye on the prize

Never satisfy a short term impulse at the expense of a long term goal.

Never do what feels good at the moment if it costs you something that matters a whole lot more in the end.

Leonard Pitts Aug. 28, 2007


Chemistry The study of matter and the changes it undergoes.


Matter

•  Atoms are the building blocks of matter. •  Each element is made of the same kind of atom. •  A compound is made of two or more different kinds of

elements.


SI Units

a different base unit for each quantity

Prefixes convert the base units into units that are appropriate for the item being measured.

Metric System


Uncertainty in measurements What is the difference between Precision and Accuracy?


Before Recitation this week

•  Read Chapters 1, 2.3-4, 5.1-3 •  Complete ALEKS prep course by midnight tomorrow. •  Transfer into ALEKS CHEM 110 Course tomorrow
