Which reaction will NOT occur in nature? C5H12 (l) + 8O2 (g) → 5CO2 (g) + 6H2O (g)
2FeCl3 (aq) + 3Sr (s) → 3SrCl2 (aq) + 2Fe (s)
Cu (s) + CaSO4 (aq) → CuSO4 (aq) + Ca (s)
Mg(NO3)2 (aq) + Na2C2O4 → MgC2O4 (s) + 2NaNO3 (aq)

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
