The electrochemical cell described by the balanced chemical equation has a standard emf (electromotive force) of -0.29 V. Calculate the Wmax (kJ) the cell has done if 31.933 g of H+(aq) (Molar Mass - 1.008 g/mol) forms. Round your answer to 3 significant figures. 2IO3-(aq) + 2Mn2+(aq) + 2H2O(l) → I2(s) + 2MnO4-(aq) + 4H+(aq)
In which case an electromotive force is producing electrical energy to the circult?
In which case an electromotive force is producing electrical energy to the circult? When the electrical current is passing through the electromotive force from its positive to negative terminals. Electromotive force is always consuming electrical energy from the electrical circuit. When the electrical current is passing through the electromotive force from its negative to positive terminals. Electromotive force is always producing electrical energy to the electrical circuit.
