A) Ethanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The combustion of one mole of ethanol releases 326.7 kcal of energy.The combustion of one mole of 2-methylhexane, C7H16, releases 1.150×103 kcal of energy. How much energy is released during the complete combustion of 495 grams of 2-methylhexane ?------------- kcalAssuming the same efficiency, would 495 grams of ethanol provide more, less, or the same amount of energy as 495 grams of 2-methylhexane? --------- B) Combustion reactions are exothermic. The heat of reaction for the combustion of 2-methylheptane, C8H18, is 1.306×103 kcal/mol. What is the heat of combustion for 2-methylheptane in kcal/gram?--------- kcal/gramHow much heat will be given off if molar quantities of 2-methylheptane react according to the following equation? 2 C8H18+25…
