Matter cannot be created or destroyed-Thats why
we must balance chemical reactions
The Good News-There are only five main types of chemical reactions
A type of reaction in which an element or compound combines with
another element or compound

Practice with Lewis Structures
Draw a Lewis Structure for each of these substances. Then determine: a) whether the
bond(s) are non-polar covalent, polar covalent, or ionic, b) whether the molecule is polar
or non-polar, c) the shape of the mo
