Question 7 (1 point) 1.75 g of but-1-ene (C4Hg) undergoes combustion and produces 28700 J of heat. The molar enthalpy of reaction for but-1-ene is abc kJ/mol. Note: Please include a negative sign, if the reaction is exothermic. Your Answer: Answer Question 8 (1 point) If the molar heat of combustion of ethane (C2H6) is -1560 kJ/mol. The heat produce when 126 g of ethane is burned is a.bc MJ. Note: Please include a negative sign,'-, if the reaction is exothermic. Your Answer: Answer
