Ms. Prohaska measures the enthalpies of combustion of propene and 1-chloroethene. She determines that the combustion of 2.00 moles of 1-chloroethene releases 23ookJ of energy according to the equation below: 2C2H3Cl (g0 + 5 O2 (g) ? 4 CO2 (g) + 2 H2O (g) + 2 HCl (g) ΔH = -2300kJ Using the standard enthalpies of formation determine whether the combustion of 2.00 mol of propene releases more, less or the same amount of energy that 2.00 mol of 1-chloroethene releases. The balanced equation for the combustion of propene is: 2 C3H6 (g) + 9 O2 ? 6 CO2 (g) + 6 H2O (g) ΔH°f for C3H6 (g) = 21 kJ/mol ΔH°f for C2H3Cl = 37 kJ/mol

Question
- Ms. Prohaska measures the enthalpies of combustion of propene and 1-chloroethene. She determines that the combustion of 2.00 moles of 1-chloroethene releases 23ookJ of energy according to the equation below:
2C2H3Cl (g0 + 5 O2 (g) ? 4 CO2 (g) + 2 H2O (g) + 2 HCl (g) ΔH = -2300kJ
Using the standard enthalpies of formation determine whether the combustion of 2.00 mol of propene releases more, less or the same amount of energy that 2.00 mol of 1-chloroethene releases. The balanced equation for the combustion of propene is:
2 C3H6 (g) + 9 O2 ? 6 CO2 (g) + 6 H2O (g)
ΔH°f for C3H6 (g) = 21 kJ/mol
ΔH°f for C2H3Cl = 37 kJ/mol
