Predict the regioisomer that forms in the given alkene reaction. 1. BH¸·THF 3 2. H₂O₂, NaOH

Complete and balance the following combustion reactions. Assume that each hydrocarbon is converted completely to carbon dioxide and water. (a) Propane + O2 (b) Octane + O2 (c) Cyclohexane + O2 (d) 2-Methylpentane + O2

The combustion of isoctane reaction produces -5099.5 kJ of heat per mole of C8H18 (g) consumed, under standard conditions.  The enthalpy of formation (DHf) for CO2(g) and H2O (g) are -393.5 kJ/mol and -241.8 kJ/mol, respectively.  Find the standard enthalpy of formation (DHf) of this isomer of C8H18 (g)? (Show work)   C8H18 (g) + O2(g) -> 8CO2(g) + 9H2O(g)  DHrxn = -5099.5 kJ

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
