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 heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of hexane, C6H14, is 995.0 kcal/mol. How much energy is released during the complete combustion of 460 grams of hexane ? kcal Assuming the same efficiency, would 460 grams of ethanol provide more, less, or the same amount of energy as 460 grams of hexane?

Ethanol, C₂H60, 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-methylheptane, C8H18, releases 1.306 × 10³ kcal of energy. How much energy is released during the complete combustion of 405 grams of 2- methylheptane? kcal Assuming the same efficiency, would 405 grams of ethanol provide more, less, or the same amount of energy as 405 grams of 2-methylheptane? more less the same amount Retry Entire Group 9 more group attempts remaining

Answer the following questions. (Be guided with the rubric below) Fossil fuels are the raw materials for many consumer products. Do you think it is wise to continue to use the limited supplies of fossil fuels as an energy source? Explain. Fruits are sometimes picked while green and transported long distances, after which they are exposed to ethene gas, which speeds the ripening process. Research and write a short paper detailing the advantages and disadvantages of using ethene to speed the ripening of fruits.
For this discussion activity, please respond to the following question: Combustion requires three primary components: fuel, energy, and an oxidizer. The fuel is the organic starting material and once the activation energy is achieved, large amounts of energy are rapidly released fragmenting reactants into individual atoms. The components quickly rearrange into smaller and more stable molecules. Oxygen serves as an oxidizer, due to its electronegativity, accepting electrons and forming products including water and carbon dioxide. Nitroguanidine (CH4N402) is used in select fertilizers and more commonly as a component to propel munitions. Suppose a field artillery soldier was calculating how much nitroguanidine was needed to propel a round. The soldier would need to consider the desired volume of gas to displace along the gun tube and the ambient operating conditions. a. Predict the reaction products for the detonation of 1 mole of nitroguanidine. b. Calculate the amount of explosive…
