Some of the images are adopted from Tro’s textbook, the only purpose of
which is to enhance student learning.
Calculations involving stoichiometric reactions, limiting reactant, and theoretical
yield, determining solution dilutions, predicting solubility of a compd, writing precipitation,
complete ionic, and net ionic equations, writing acid-base reactions, calculations involving acid-
base titrations, writing gas evolution, combustion, and redox reactions, assigning oxidation states.

What does a balanced equation mean? A lot! We experience chemical reaction on a daily basis
and never understand what they represent. If we understood all that we would have been able to
tell ourselves how much food we need to eat to survive, how does fat grow due to eating too
much carbohydrate, how do we contribute to acid rain that spoils our harvest, why it fizzes when
we add baking soda to orange juice?
Consider the combustion reaction of octane:
Reactions happen by the mole bundle
The coefficients in a chemical reaction specify the relative amounts in moles of each of
the substances involved in the reaction.
How many mole ratios exist in the above equation?
