Answer #1

This is a two-step problem. Our first step is to determine how many *moles* of CO2 are produced when 5.0 x 102 kJ of heat are generated. We do this by examining the reaction equation given in the problem and recognizing that 1 mole of CO2 is produced when 393.5 kJ of heat are generated:

Next, we simply convert our 1.27 moles of CO2 to grams using its molar mass (44 grams per mole):

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);...
