Consider the combustion of ethane (c2h6), a component of natural gas. a. provide the balanced stoichiometric equation for combustion. b. do calculations to derive a lower heating value and high heating value (in mj/kg or kj/g), beginning with enthalpies of formation of the compounds involved in combustion. cite your source for the heat of formation, which you can find many places online. c. based on molecular weights and your equation in part a, calculate the co2 produced per kg of ethane combusted. d. suppose the ethane is combusted in a gas-fired power plant with an efficiency of 45%. use your answers from parts b and c to find co2 emissions per kwh of electricity produced. be careful converting your units of energy.
