Correction: 3Fe2O3(s) + CO(g) ---> 2Fe3O4(s)+ CO2(g) ΔH° = -59kJ Is this right? FeO(s) + CO(g) ---> Fe(s) +CO2(g) ΔH° = -28/2 ΔH° = -14
Is this correct? (x ^ 2) / 2.0 = 5.0 x 10 ^ -2 x = 3.162E-1 = [H +] = [H2PO3-] pH = -log (3.162E-1) = 0.50
x^1 - 6.25E-3 + 2.0625E-4 = 0 x = {-(-6.25E-3) +/- sqrt[(6,25E-3)^2 - (4*1*2.0625E-4)]}/(2*1) x = -1.089E-2 (Not x) or 1.714E-2 pOH = -log(1.714E-2 = 1.76 pH = 14-1.76 = 12.24
Is this the right answer? Kb = 1E-14 / 1.6E-12 = 6.26E-3 x^2/-0.033 = 6.26E-3 x = 1.436E-2 pOH= -log(1.436E-2)= 1.84 pH= 14 - 1.84 = 12.16
