[Review Topics] [References] Use the References to access important values if needed for this question. Ethanol, C2H,O, 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, C,H14, is 995.0 kcal/mol. How much energy is released during the complete combustion of 479 grams of hexane ? kcal Assuming the same efficiency, would 479 grams of ethanol provide more, less, or the same amount of energy as 479 grams of hexane?

500.0 mL of 0.100 mol·L HCl(aq) was added to a high quality insulated calorimeter containing 500.0 mL of 0.100 mol·LNaOH(aq). Both solutions had a density of 1.000 g·mL and a specific heat of 4.184 J·g ·K . The calorimeter had a heatcapacity of 850.0 J·K . The temperature of the entire system rose from 25.50 C to 26.05 C.Calculate the heat of reaction. Thank you!
