Many transition metals can undergo a series of reaction similar to those of the copper reactions in this experiment. Identify the type of reaction for each of the chemical equations below involving manganese. Mn(OH)2(s) + heat Mn0(s) + H20(g) Choose... Mn(s) + 2 H2SO4(aq) → MnSO4(aq) + H2(g) Choose... MNSO4(aq) + Na2S(aq) → MnS(s) + Na2SO4(aq) Choose... Mn2+(aq) + H202(aq) + 2 OH (aq) → MnO2(s)+ 2 H20(1) Choose... MNSO4(aq) + 2 NaOH(aq) → Mn(OH)2(s) + Na2SO4(aq) v Choose. metathesis hydrolysis

Balance the following chemical equation (if necessary): ZnS(s) + AIP(s) → Al,S3(s) + Zn3P2(s)

Write appropriate balanced net ionic equations for each of the following processes. A3. Concentrated Nitric acid oxidizes Cu(s) to Cu²+ (aq): B2. NaOH converts Cu²+ (aq) to insoluble Cu(OH)₂(s). C1. Heat converts Cu(OH)₂(s) to CuO(s).

The iron content of iron ore can be determined by titration with a standard KMNO4 solution. The iron ore is dissolved in HCl, and all the iron is reduced to Fe+ ions. This solution is then titrated with KMNO4 solution, producing Fe* and Mn2+ ions in acidic solution. If it required 42.41 mL of 0.0452 M KMNO4 to titrate a solution made from 1.236 g of iron ore, what is the mass percent of iron in the iron ore? Mass percent = %
