3. Lighters are usually fueled by butane (C4H10). When 2.00 mol of butane burns at constant pressure, it produces 5316 kJ of heat and does 6.00 kJ of work. What are the values of ΔH and ΔU for the combustion of one mole of butane?
(A) ΔΗ = −2658 kJ； ΔU = −2655 kJ
(B) ΔΗ = −2658 kJ； ΔU = -3 kJ
(C) ΔΗ = –2658 kJ； ΔU = −2661 kJ
(D) ΔΗ = 5316 kJ； ΔU = 5322 kJ
(E) ΔΗ = −5316 kJ； ΔU=-5322 kJ
