question 3

Multiple Choice

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)\(\rightarrow\) 2 Cl₂(g)+ 8 CO₂(g)+ 10 H₂O(g)
• B)4 C₂H₅Cl(g)+ 13 O₂(g)+ 5145 kJ \(\rightarrow\) 2 Cl₂(g)+ 8 CO₂(g)+ 10 H₂O(g)
• C)4 C₂H₅Cl(g)+ 13 O₂(g)\(\rightarrow\) (5145 kJ)\(\rightarrow\) 2 Cl₂(g)+ 8 CO₂(g)+ 10 H₂O(g)
• D)4 C₂H₅Cl(g)+ 13 O₂(g)\(\rightarrow\) 2 Cl₂(g)+ 8 CO₂(g)+ 10 H₂O(g)?0?H = +5145 kJ
• E)4 C₂H₅Cl(g)+ 13 O₂(g)\(\rightarrow\) 2 Cl₂(g)+ 8 CO₂(g)+ 10 H₂O(g)?0?H = -5145 kJ
