Which Of The Following Are Balanced Equations

Which Of The Following Are Balanced Equations If a fractional coefficient has been used multiply both sides of the equation by the denominator to obtain whole numbers for the coefficients Count the numbers of atoms of each kind on both sides of the equation to be sure that the chemical equation is balanced Example 7 4 1 7 4 1 Combustion of Heptane

To balance a redox equation using the half reaction method the equation is first divided into two half reactions one representing oxidation and one representing reduction The equations for the half reactions are then balanced for mass and charge and if necessary adjusted so that the number of electrons transferred in each equation is the same To balance a chemical equation enter an equation of a chemical reaction and press the Balance button The balanced equation will appear above Use uppercase for the first character in the element and lowercase for the second character Examples Fe Au Co Br C O N F Ionic charges are not yet supported and will be ignored
