How Do I Balance This Equation (MnO4-(aq) + Br-(aq)... | Yahoo Answers

MnO4- is an oxidizing agent, SO32- is a reducing agent. Reactants: MnO4-. SO32-. H+.Balance the reaction MnO4Ð(aq) + SO32Ð(aq) → MnO2(s) + SO42Ð(aq) in basic solution. 6) Convert to basic solution by replacing the H+ with H2O and adding the same number of OHÐ ions to the other side MnO4Ð + 4H2O + 3eÐ → MnO2 + 2H2O + 4OHÐ.PbO2(s) + SO42-(aq) + 4 H+1(aq) + 2e-1 -> PbSO4(s) + 2 H2O(l). BrO3-1(aq) + 6 H+1(aq) + 6e-1 -> Br-1(aq) + 3 H2O(l). MnO2(s) + 4 H+1(aq) + 2e-1 -> Mn2+(aq) + 2 H2O(l). AgBr(s) + e-1 -> Ag(s) + Br-1(aq).CH3OH + MnO4- = CO32- + MnO42 MnO4- + Br- = MnO2 + BrO3- + OH

2 MnO4−(aq) + Br−(aq) → 2 MnO2(s) + BrO3−(aq) + H2O(l) Balance hydrogen by adding hydrogen ions. Step 2: To balance electrons, adjust the coefficients by multiplying electrons gained by 5. Since each iodine molecule has 2 atoms, the coefficient for IO3...MnO2(s) + BrO3-(aq). {Second step: Assign oxidation numbers}. Reactants: Mn +7 and Br -1. Products: Mn +4 and Br +5. Multiply Mn-containing species by 2 to balance change in oxidation number. 2MnO4-(aq) + Br-(aq).I-(aq) + MnO4-(aq)  Mn2+(aq) + I2(s) 2. Write a balanced net ionic equation for the following reaction in basic solution using both Balance the folioing redox reactions via the 1/2 reaction method - Show all workMnO4- + Br- => MnO2 + BrO3-( In basic solution).So we have 1 Mole MnO4- on the left. So leaving out the Br's, what do we have that needs to be balanced: 8H+ + MnO4 - ==> Mn++ + 4 H2O. How do you balance this chemical equation using the half-reaction method: "BrO3 - (aq) + SO2(g) = SO4 2- (aq)...

Standard Reduction Potentials

MnO2(s). 3. 86.936845. BrO3(aq). Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide. Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are enter reagents only and click 'Balance'.NH3 (aq) + HNO3 (aq) = NH4NO3 (aq) is classified as what kind of reaction? Select the best statement relating to the following reaction: 2MnO2 (s) + KClO3 (aq) Balance and select the correct coefficient for the bromide anion. Br2 + OH = Br + BrO3 + H2O.> 2MnO4⁻ +5Bi³⁺ + 5Na⁺ +16H⁺ +15H2O. 2Mn²⁺ + 5 NaBiO3+14H⁺ ---> 2MnO4⁻ +5Bi³⁺ + 5Na⁺ +7H2O.9 NAME_ 9. (16 points) Consider the reaction: 2 Ag+(aq) + Zn(s) 2 Ag(s) + Zn2+(aq) A.(4 points) What is the standard cell potential for this reaction? B.(4 points) For a voltaic cell based on this reaction, which half-reaction would take place at...1)2MnO4 −(aq)+Br−(aq)+H2 O(l)⟶2MnO2 (s)+BrO3 (aq)+2OH−(aq). Here, instead of solving the overall reaction we solve as half reactions. MnO4 −+4H++3e−→MnO2 +2H2 O----- (Reduction). As in the reduction reaction no. of e- involved is half that of the one in the oxidation we will multiply the...
