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.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
