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.

Explanation:
The problem deals with a phase transition from solid to liquid. To the left we have ice and to the right we have liquid water.
For such change to take place, the process of melting must occur. During melting, a solid changes state from solid to liquid by taking energy from the environment.
- In solid state, the molecules of the water are in a fixed state about their fixed lattice.
- As the solid ice gains energy from the environment, it begins to melt.
- Energy increase causes the molecules of the water to start flowing to form a liquid.

They can use the properties to test and come to some kind of conslusion about the object because in some way it's gotta correlate back to one of the different properties of matter.
