Natural gas is mostly methane, but it also contains some ethane and propane. The enthalpies of combustion of methane, ethane and propane are -810, -1420, and -2030 kJ mol-1, respectively. (A) Complete the chemical reactions for the combustion of these fuels and calculate the amount of heat released per mole of oxygen and carbon dioxide produced for the three gases using the enthalpy of the reaction. i. For methane: CH4 + O2 -> ___________ Heat released per...

Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions (1 atm and 25 �C). Each must be in mol * MJ^-1 (a) coal, C(s, graphite) (b) natural gas, CH4(g); (c) propane, C3H8(g);...
