Question 2 (1 point) Cooking gas contains mostly butane. During complete combustion of one mole of butane, 2658 kJ of heat is released. The balanced thermochemical equation, using AH notation, to represent enthalpy change of combustion of butane is CH06 +0,6) + 4CO26) +5H40 ) AH = -2658 k) 2C,H1069) +130260) + BC026) + 104,0) AH = -2658 k) CH106) + 026 40026 +54,06) AH = +2658 kJ 2C, H.268) + 1302) 8C026) + 101,0) AH = +2658 k) Ouection 21
