I have included the work in the attached file. The correct answer is C. 28.2 grams of Carbon
Answer:
7.146
Explanation:
use the equilibrium equation
I think that it is true to the bone
ΔH = -420.16 KJ when 2.6 g of S₈ reacts.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given reaction balanced equation is:
1/8 S₈(s) + H₂(g) → H₂S(g) ΔH = -20.22kj
Now,
1/8 mol of S₈ reacts ΔH = -20.2 kJ
1 mol will react ΔH = -20.2 × 8
= -161.6 KJ
2.6 mol will react ΔH = -161.6 × 2.6
= -420.16 KJ
Thus from the above conclusion we can say that ΔH = -420.16 KJ when 2.6 g of S₈ reacts.
