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) The metal with the higher heat capacity.
Explanation:
The heat (Q) absorbed by a metal can be calculated using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the metal
m is the mass of the metal
ΔT is the change in the temperature
Q = c × m × ΔT
ΔT = Q/ c × m
Considering both metals have equal mass (m) and are subject to the same amount of heat (Q), the change in the temperature is inversely proportional to the specific heat capacity. The metal with the higher specific heat capacity will undergo the smallest change in temperature.
Sulfur - S-16
