Balance the following half-reaction: NO NO3 1. The first species to balance is the redox active species, the element that is changing oxidation state. In this reaction, the redox active species, N, is already balanced. 2. How many moles of H2O must there be on the reactant side of this half reaction? (Enter 0 if no moles of water are needed or enter #H2O where # moles of water are needed, e.g. if 4 moles of H2O are needed, type 4H2O). Enter your answer in the box on the left. How many moles of HO must there be on the product side of this half reaction? (Enter 0 if no moles of water are needed or enter #H20 where # moles of water are needed, e.g. if 4 moles of H2O are needed, type 4H20). Enter your answer in the box on the right. + NO-> + NO3 Submit Answer Tries 0/45 3. How many moles of protons must there be on the reactant side of this half reaction? (Enter 0 if no moles of H+ are needed or enter #H+ where # moles of H+ are needed, e.g. if 4 moles of H+ are needed, type 4H+). Enter your answer in the box on the left. How many moles of protons must there be on the product side of this half reaction? (Enter 0 if no moles of H+ are needed or enter #H+ where # moles of H+ are needed, e.g. if 4 moles of H+ are needed, type 4H+). Enter your answer in the box on the right. + 2H2O + NO Submit Answer Tries 0/45 + NO3 4. You now have mass balance but will need to balance charge. This will be done by adding electrons to the side of the reaction with excess positive charge. How many moles of electrons must there be on the reactant side of this half reaction? (Enter 0 if no moles of electrons are needed or enter #e where # moles of electrons are needed, e.g. if 4 moles of elecrons are needed, type 4e). Enter your answer in the box on the left. How many moles of electrons must there be on the product side of this half reaction? (Enter 0 if no moles of electrons are needed or enter #e where # moles of electrons are needed, e.g. if 4 moles of elecrons are needed, type 4e). Enter your answer in the box on the right. + 2H2O + NO + 4H+ + NO3 Submit Answer Tries 0/45 The difference between these two oxidation states, +2 and +5, should be the same as the number of electrons in the balanced half-reaction, Submit Answer Tries 0/45
