7.6 is the answer for the question

Answer:
pretty sure it is letter B
Answer:
2.5moles of Fe(OH)3
Explanation:
i don't know how to explain this
The volume fraction in gasses is equal to the mole fraction.
In a reaction mixture, the molar ratio of X : Y = 1:4
Fraction of X = 1/5
Fraction of Y = 4/5
So in the 5 L reaction mix,
1 L of X and 4 L of Y
The products contain 2 L of Z
This satisfies the equation completely so we check the enthalpy of this reaction:
-75 kilojoules
