Balancing Chemical
Equations Notes

Think back! What is the Law of
Conservation of Matter?

Matter can not be created or destroyed, it can be
transformed from one form to another.
+
Why is this important for chemical
equations?

Same number of each element on the reactant side as the
product side

Balanced

Mr. Klotz’s Tips for Balancing
Equations

Must satisfy the law of conservation of matter

Only use whole number coefficients

All atoms should be present on both the reactant and product
side of the equation

Check to see if the equation is already balanced

Coefficients go in front of the substance and multiply all
subscripts
+
Mr. Klotz’s tips for balancing
equations continued

One (1) is understood and does not have to be written as a
coefficient

All coefficients should be reduced to lowest terms

Balance most complex species first and then move to single
atoms

Double check your work!
