Chem105 Study guides, Class notes & Summaries

An overview of stoichiometry and how it is used in general chemistry. Includes several different problems and how they are worked out in the sense of this topic.

An introduction to thermodynamics in chemistry. Includes each law of thermodynamics, work, melting curves, and heat capacity. Also includes one problem based on melting curves. There is mention of exothermic versus endothermic reactions.

An introduction and description of the types of intermolecular forces and how to determine the polarity of a molecule. Detailed instruction on how to determine if a molecule is polar based on its electronegativity. Also includes an overview of molecular orbitals and orbital numbers.

This document has a brief review of some very common unit conversions that are used in chemistry. It also includes an overview of isotopes. There are problems that involve finding the average atomic mass and percent abundance for an element that has multiple isotopic forms in nature.

An overview of how to write electron configurations for atoms. This includes full electron configurations and noble gas configurations. Shows helpful hints to understanding how to write these out. Includes a summary of some periodic trends that exist within the periodic table.

This is a basic overview of energy. Includes what energy is and how it is related to chemistry. Contains equations that deal with frequency, wavelength, and energy. Goes through some questions that deal with solving energy problems in regard to wavelength and frequency. Also includes some information on photon energy and its relation to wavelengths and frequency.

This paper thoroughly discussed the laboratory experiment about the Bunsen burner. I. Introduction Almost all laboratory burners used today are modifications of the original Bunsen burner that was developed by Robert Bunsen and Peter Desaga in 1855. At that time, he was conducting his research on isolating chemical substances and needed a reliable burner for his new laboratory at the University of Heidelberg. He needed a burner with a flame that is steady, clean and hot, characteristics tha...
