ΔH = -15.78 KJ when 25.0 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,
When 1 mol will react, then ΔH = -20.2 × 8
= -161.6 KJ
When 1 mol of S8 = 8 × 32 g
= 256 g
When 256g of S8 react ΔH = -161.6 KJ
When 1 g reacts, ΔH =
=- 0.63125 KJ
When 25 g reacts, ΔH = - 0.63125 × 25
= -15.78 KJ
Thus from the above conclusion we can say that ΔH = -15.78 KJ when 25.0 g of S₈ reacts.

<h3>Conclusion. A good friendship is very difficult to come across. That is why we should appreciate this divine relationship that is based on understanding and feelings. ... A true friend is one of the most precious possessions that one can have in his life.</h3>
Hope it's helpful for Yuh bro!!
The vapors of some chemicals used in the chemistry laboratory, especially isocyanates, can react and bond the contact lens to the eye.
(FYI - the family of isocyanates include Superglue..I wouldn't want to have been the person who discovered this unfortunate reaction!)
