The third step in balancing the redox reaction using oxidation-number-change is

• 5. Check the balancing for both atoms and charge.

• 4. Use coefficients to make the total increase in oxidation number equal to the total decrease in oxidation number.

• Assign oxidation numbers to each of the atoms in the equation and write the numbers above the atom.

• Use a line to connect the atoms that are undergoing a change in oxidation number.

The last step in balancing the redox reaction using oxidation-number change method is check the balancing for both atoms and charge.

• True

• False
