Hello, im a student it counted my answer wrong can you redo the problem plz. thanks

Consider the following reductions. Cr2+(aq) + 2 e- ⟶⟶ Cr(s)                              Eored = - 0.910 V Co2+(aq) + 2 e- ⟶⟶ Co(s)                            Eored = - 0.280 V Which element is the better oxidizing agent? Explain your answer.

For the reaction 2Na(s) + 2H₂O(1)→ 2NaOH(aq) + H₂(g) AH = -368.6 kJ and AS° = - 15.3 J/K The standard free energy change for the reaction of 1.87 moles of Na(s) at 300 K, 1 atm would be kJ. This reaction is standard conditions at 300 K. Assume that AH and AS are independent of temperature. favored under Submit Answer 9 more group attempts remaining Retry Entire Group Next
