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!

BaS + NaCl  Na2S + BaCl2 Example 1

BaS + 2 NaCl  Na2S + BaCl2 Answer

P + O2  P2O5 Example 2

4P + 5O2  2P2O5 Answer

Na2O2 + H2O  NaOH+ O2 Example 3 You Try!

2Na2O2 + 2H2O  4NaOH+ O2 Answer
