Which of the following represents the total amount of energy, in kJ, required to form one mole of oxide ions from one mole of oxygen atoms? (1st *EA* of oxygen = −141 kJ mol−1-141 \text{ kJ mol}^{-1} ; 2nd *EA* of oxygen = 753 kJ mol−1753 \text{ kJ mol}^{-1} ; NA=6.02×1023 mol−1N_A = 6.02 \times 10^{23} \text{ mol}^{-1} ) a. −141-141 b. −141×2×6.02×1023-141 \times 2 \times 6.02 \times 10^{23} c. (−141+753)×6.02×1023(-141 + 753) \times 6.02 \times 10^{23} d. −141+753-141 + 753
