- As stated in Section 11-9, the wax found in apple skins is an unbranched alkane with the molecular formula C^H^. Explain how the presence of this alkane in apple skins prevents the loss of moisture from within the apple.arrow_forwardWhat are ALL the types of intermolecular bonding does n-pentane have? What are ALL the types of intermolecular bonding does 1-butane have?arrow_forwardEthanol, 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 heat of combustion of ethanol is 326.7 kcal/mol.The heat of combustion of 2-methylhexane, C7H16, is 1.150×103 kcal/mol. How much energy is released during the complete combustion of 446 grams of 2-methylhexane ??? kcalAssuming the same efficiency, would 446 grams of ethanol provide more, less, or the same amount of energy as 446 grams of 2-methylhexane?arrow_forward
