Balancing Rules:
1. Determine the correct formula for all reactants and products (use P.T. and ion sheet) 2. Reactants on left of arrow, products on right 3. Count the number of atoms of each element on each side 4. Balance one element at a time using coefficients a. NEVER CHANGE SUBSCRIPTS 5. Double check your work 6. if needed, reduce coefficients to lowest whole number ratio Common errors: 1. Writing incorrect chemical formulas 2. Balancing by changing subscripts instead of adding coefficients |
