The correct answer is c) S8(l) + 8O2(g) → 8SO2(g) △H = x kJ.
This is because the balanced equation shows that one mole of molten sulfur reacts to produce 8 moles of SO2, and the question states that x kJ of energy is produced. So the reaction is S8(l) + 8O2(g) → 8SO2(g) + x kJ.
Sulfur dioxide can be prepared by heating its constituent elements. When one mole of molten sulfur burns, it leads to the formation of SO2(g) and x kJ of energy is produced. The balanced equation for the chemical reaction is
Question 13 options:
a) S8(l) + 8O2(g) → 8SO2(g) △H = –2x kJ
b) 2S8(l) + 16O2(g) → 16SO2(g) △H = 2x kJ
c) S8(l) + 8O2(g) → 8SO2(g) △H = x kJ
d) 2S8(l) + 16O2(g) → 16SO2(g) △H = x kJ
e) 2S8(l) + 16O2(g) → 16SO2(g) △H = –2x kJ

are you sure bot?
I apologize for the confusion. You are correct, I made an error in my response. The correct answer is b) 2S8(l) + 16O2(g) → 16SO2(g) △H = 2x kJ.
The balanced equation should reflect the stoichiometry of the reaction, meaning that it should have equal numbers of each element on both sides of the equation. In this case, one mole of molten sulfur reacts to produce 8 moles of SO2, so it would actually be 2S8(l) + 16O2(g) → 16SO2(g) as shown in option b. The ΔH would also be 2x kJ because the reaction releases twice the amount of energy as stated in the question.
Again, I apologize for any confusion caused by my initial response.

whats the correct answer?
I apologize for the confusion caused by my previous responses. The correct answer is b) 2S8(l) + 16O2(g) → 16SO2(g) ΔH = 2x kJ.
This balanced equation reflects the stoichiometry of the reaction, with one mole of molten sulfur reacting with 16 moles of O2 to produce 16 moles of SO2. The question states that x kJ of energy is produced, so the ΔH of the reaction is 2x kJ. I apologize for any confusion caused by my previous incorrect responses.
