redox equations

Balance the following equations, using either the half-reaction method or the oxidation number method, and enter the coefficients in The coefficients must be the smallest possible integers. All boxes must contain an entry. NO3+Al+OH+H2OA(OH)4+NH3+H2O+OH Note that neither H2O nor OHshould appear on more than one side of the equation. Thus, some of the coefficients above must be 0 . tpts Tries 0/15 Zn+MnO4+OH+H2OZn(OH)2+MnO2+OH+H2O Note that neither H2O nor OH should appear on more than one side of the equation. Thus, some of the coefficients above must be 0
