Balancing Chemical Formulas This tutoring session is designed
to help anyone who is struggling balancing equations
Slide 3
Remember! Matter can never be created nor can it be destroyed
(Theory of conservation of matter) This means that whatever
elements go into a chemical equation (Reactants) must also come out
of the chemical equation (Products) So the goal when balancing a
chemical formula is just to make sure you have the same number of
atoms on each side The catch is, that you can only manipulate the
amount of each molecule
Slide 4
2 Hydrogens 2 Oxygens 2 Hydrogens 1 Oxygen
Slide 5
Slide 6
ONLY Change the Big Number Remember, when balancing an equation
you can only change the big number out front (Coefficient) That
number multiplies all of the atoms in the compound it is in front
of You can change the amount of the molecule in the equation, but
you cannot change the molecule So dont put coefficients inside of a
molecule and dont try to change the subscript (small) numbers
