A. Balance the following redox rxn Fe3+ + NO2- + H2O ---> Fe2+ +H+ + NO3-...

A. Balance the following redox rxn

Fe3+ + NO2- + H2O ---> Fe2+ +H+ + NO3-

B. at 25 deg C 0.0840 mol of generic salt AB2 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 deg C?

C. 0.740 mol of SO3 is placed in a 4.50 L container

2SO3(g) = 2SO2(g) + O2(g)

At equilibrium, 0.130 mol of O2 is present. Calculate Kc?

D. 2H2O(g) = 2H2(g) + O2(g) proceeds at a temp until partial pressures of h2o, h2, O2 reach 0.0650 atm, 0.00150, and 0.00650 respectively. What is Te value of the equilibrium constant at this temp?
