When C2H5Cl(g) is burned in oxygen,chlorine gas is produced in addition to carbon dioxide and water vapor.5145 kJ of heat are released for every four moles of C2H5Cl(g) burned.Which of the following correctly represents the thermochemical equation?
A) 4 C2H5Cl(g) + 5145 kJ + 13 O2(g) 2 Cl2(g) + 8 CO2(g) + 10 H2O(g)
B) 4 C2H5Cl(g) + 13 O2(g) + 5145 kJ 2 Cl2(g) + 8 CO2(g) + 10 H2O(g)
C) 4 C2H5Cl(g) + 13 O2(g) (5145 kJ) 2 Cl2(g) + 8 CO2(g) + 10 H2O(g)
D) 4 C2H5Cl(g) + 13 O2(g) 2 Cl2(g) + 8 CO2(g) + 10 H2O(g) ?0?H = +5145 kJ
E) 4 C2H5Cl(g) + 13 O2(g) 2 Cl2(g) + 8 CO2(g) + 10 H2O(g) ?0?H = -5145 kJ
