For each requested step, use the half-reaction method to balance the oxidation-reduction
Chapter 19, Problem 11(choose chapter or problem)
For each requested step, use the half-reaction method to balance the oxidation-reduction equation below. (Hint: See Sample A.) K+H20*KOH+H2 a. Write the ionic equation, and assign oxidation numbers to all atoms to determine what is oxidized and what is reduced. b. Write the equation for the reduction, and balance it for both atoms and charge. c. Write the equation for the oxidation, and balance it for both atoms and charge. d. Multiply the coefficients of the oxidation and reduction equations so that the number of electrons lost equals the number of electrons gained. Add the two equations. e. Add species as necessary to balance the overall formula equation.
