The following half-reaction method is used to balance oxidation-reduction equations. (1) determine which atoms change oxidation state from reactant to product in the reaction. (2) identify and write half reactions (oxidation and reduction). (3) return to the original chemical equation to balance it. (a) insert the coefficients from the half reactions first. (b) inspect the number of each atom on each side for all elements. which important step is missing from this procedure? check other reactions similar to this one. name the elements that are involved in the reaction. make sure the reduction half reaction is identified first. balance the half reactions based on the number of electrons.

Write "true" or "false" for each statement. (a) we balance chemical equations as we do because energy must be conserved. (b) if the reaction 2 o3(g) s 3 o2(g) goes to completion and all o3 is converted to o2, then the mass of o3 at the beginning of the reaction must be the same as the mass of o2 at the end of the reaction. (c) you can balance the "water-splitting" reaction h2o(l) s h2(g) + o2(g) by writing it this way: h2o2(l) s h2(g) + o2(g).

Which of the following is not a step in balancing redox reactions in acidic solution, using the half-reaction method? a) h2o and oh- are added as needed to the half-reaction equations to make the number of oxygen and hydrogen atoms balance. b) divide the chemical equation into two half-reaction equations, identifying which half-reaction is oxidation and which is reduction. c) h2o and h+ are added as needed to the half-reaction equations to make the number of oxygen and hydrogen atoms balance. d) multiply each term in one of the half-reaction equations by a factor that will make the number of electrons lost (in the oxidation) equal to the number of electrons gained (in the reduction).
