A denitrification process (biological process) is dominated by the following redox half reactions: \mathrm{NO}_{3}^{-}+\mathrm{H}^{+}+\mathrm{e}^{-} \rightarrow \mathrm{N}_{2}+\mathrm{H}_{2} \mathrm{O} \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COO}^{-}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{CO}_{2}+\mathrm{HCO}_{3}^{-}+\mathrm{H}^{+}+\mathrm{e}^{-} Please balance the net reaction. When 1 g of benzoic acid is consumed, how many milligrams of nitrogen gas, carbon dioxide, and water will be produced, respectively?
