This multi-part module introduces covalent bonding and Lewis structures as a model of covalent bonding.Starting with valence electrons, a method of connecting unpaired electrons and/or redistributing valence electrons to satisfy the octet rule is introduced.Numerous examples are presented including CO, ozone, and polyatomic ions
This module is an introduction to the relationship between stoichiometric coefficients, limiting …
This module is an introduction to the relationship between stoichiometric coefficients, limiting and excess reactant, and theoretical yield. Includes a worked example asking for theoretical yield given two starting masses, to identify the limiting reactant, and calculate the percent yield from a given hypothetical "actual" yield.
