Write balanced net ionic equations for the following reactions in basic solution

Question

Write balanced net ionic equations for the following reactions in basic solution: Express your answer as a balanced net ionic equation. Identify all of the phases in your answer. A) MnO4{-}(aq) + C2H5OH(aq) -----> MnO2(s) + CH3CO2H(aq) B)H2O2(aq) + Cr2O7{2-}(aq) ----> O2(g) + Cr{3+}(aq) C)Sn{2+}(aq) + IO4{-}(aq) -----> Sn{4+}(aq) + I{-}(aq) D)PbO2(s) + Cl{-}(aq) -----> PbCl2(s) + O2(g)

Explanation / Answer

PbO2(s + 4H+ + 2e- --> Pb+2(aq) + 2H2O(l) 2Cl-(aq) -->cl2(g) + 2e- add PbO2(s) + 4H+(aq) + 2Cl-(aq) --> Pb+2(aq) + Cl2(g) + 2H2O(l) Make 4H+ ==> 4HCl and add 2Cl- to other side becomes PbO2(s) + 4HCl(aq) --> PbCl2(aq) + Cl2(g) + 2H2O(l) ================================
