# CHEM 1101 Lecture Notes - Lecture 1: Scientific Notation, Periodic Table, Chemical Formula

8 views1 pages

These are things that I expect you to ALREADY know/be

able to do – though we will review them in passing, and if

you haven’t been taught any of these, you are welcome to

come see me for help:

Arithmetic: rearrange linear equations and solve for any variable

Arithmetic: solve quadratic equations (quadratic formula given)

Exponential and scientic notation

Conversions from one unit to another (conversion factors given)

Insert or remove unit prexes (prex values not given)

Electromagnetic radiation and relation between energy and wavelength E

= h c / λ

Electron congurations (not necessarily the exceptions) from Periodic

Table/atomic number

Periodic table – molar mass given a chemical formula

Use units of molarity and do dilution calculations

Balancing chemical equations by inspection

Stoichiometry including limiting
