Consider the oxidation of thiosulfate (S2O3 2- ) to sulfate (SO4 2- ) and the reduction of hypochlorous acid (HOCl) to chloride (Cl- ). a. Write the oxidation half-reaction. b. Write the reduction half-reaction. c. Write the overall balanced reaction. d. Determine the number of electron equivalents per mole for HOCl in this reaction.

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

Which of these conditions most likely produces an unstable isotope?
