Problem

In acidic solution, balance the following redox half-reaction by supplying all missing coefficients, including electrons. Provide the five coefficients in order (Cr2O72−Cr_{2}O_{7}^{2-}, H+H^{+}, e−e^{-}, Cr3+Cr^{3+}, H2OH_{2}O), separated by commas. __ Cr2O72−Cr_{2}O_{7}^{2-} + __ H+H^{+} + __ e−e^{-} →\rightarrow __ Cr3+Cr^{3+} + __ H2OH_{2}O
