January 25, 2011 -- Balancing Equations

Today we reviewed something we learned many times before: how to balance equations.

To balance an equation, all you have to do it multiply each side of the equation until both sides of the equation, the reactant and the product, have the same number of atoms.

For example, Al + O2 -> Al2O3 would become 4Al + 3O2 -> 2Al2O_3.
