Answer:
133.56kPa
Explanation:
Applying Pressure Law,
P/T = P'/T'....................... Equation 1
Where P = Initial pressure, T = Initial Temperature, P' = Final pressure, T' = Final Temperature.
From the question, we were asked to calculate P'
There, we make P' the subject of the equation
P' = PT'/T...................... Equation 2
Given: P = 100kPa, T = 25°C = (273+25) = 298K, T' = 125°C = (273+1250K = 398 K
Substitute these values into equation 2
P' = (100×398)/298
P' = 133.56kPa
Hence the pressure is 133.56kPa
Answer:
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.
Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...

For 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.
<h3>What is a balanced Reaction ?</h3>
A reaction in which the number of atoms in reactants is equal to the number of atoms in the products is called a balanced reaction.
The reaction given in the question is
S₂O₈²⁻ + 2I⁻ ⇄ 2SO₄²⁻ + I₂
I₂ + 2S₂O₃²⁻ ⇄ 2I⁻ + S₄O₆²⁻
Adding the equation will give balance equation
S₂O₈²⁻ + 2I⁻ + 2S₂O₃²⁻ ⇄ 2SO₄²⁻ + 2I⁻ + S₄O₆²⁻
So x moles of S₂O₈²⁻ require 2x of S₂O₃²⁻
for 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.

Hello!
In this case, for the given reaction, we can write the equation to compute the entropy change as shown below:
Letting:
We obtain the entropy change per mole of Fe2O3(s):
Finally, the total entropy change when 1.73 moles of Fe2O3(s) react turns out:
