<h3>Determine an expression that can be used to determine Cl2O(g)</h3>
The general expression for ΔS°rxn of a chemical reaction
ΔS°rxn = ∑mS°products - ∑nS°reactants
where ; m and n = stoichiometry coefficients
Considering the given reaction : H₂O(g) + Cl₂O(g) → 2HCIO (g)
S°rxn =
------- ( 2 )
Rearranging the equation above
Hence we can conclude that The expression that can be used to determine Cl2O(g) is ;

The statement which describes the potential and the kinetic energy of the water is this: THE POTENTIAL ENERGY INCREASES AND THE AVERAGE KINETIC ENERGY REMAINS THE SAME.
At boiling point of water, the heat that is been added to the water is used to break the chemical bonds that holds the molecules of the water together so that they can turn into vapour. At this point, the average kinetic energy of the water remains the same while the potential energy increases.
The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
Answer:
Hello, Your answer is <em>B) Making observations</em>
<u><em>(Hope That Helps Your Answer)</em></u>
Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
Hope this helps!
