Helpful hints for balancing chemical equations • Balance hydrogens second to last • Balance oxygens last • Check for lowest ratio • Coefficients must be whole numbers • Don’t break up your compounds with coefficients • NaCl cannot become Na6Cl • Do not change your subscripts • Balance the polyatomic ions as one unit (if it didn’t break apart) • Perform a final check
Balance the following • C2H6 + O2 --> CO2 + H2O • Na3PO4 + Mg(NO3)2 --> NaNO3 + Mg3(PO4)2
