Web3Cu2+ (aq) + 6e− → 3Cu (s) First divide the equation into the oxidation half-reaction and the reduction half-reaction. Then, balance charge by adding electrons as needed. Finally, multiply the half-reactions by an integer to make the number of electrons lost in the oxidation half-reaction equal to the number of electrons gained in the reduction half-reaction. WebOct 23, 2024 · The equation is given as; In the equation above, the enthalpy change (-542kJ) is for the 2 moles of HF produced. The question asked for the enthalpy change per mole(One mole). So what we need to do is divide the enthalpy value of 2 moles by 2. Hence we have; 542kJ = 2 moles. x = 1 mole. x = (542* 1) / 2. x = - 271kJ
