The expression that can be used to determine Cl2O(g) is ;
<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 ;

Answer:
A wave character exhibited by all particles
Explanation:
The central idea in quantum mechanics is the paradox of wave-particle duality. In quantum mechanics, all particles are believed to also exhibit wavelike characters.
The electron is assumed to behave as a wave hence its position can not be precisely determined according the Heisenberg's uncertainty principle.
These are the underlying postulates that informed Erwin Schrödinger's wave mechanical model of the atom.
Hence, the basic postulate of quantum mechanics is that a wave character is exhibited by all particles.
