Answer : The process is not spontaneous.
Explanation :
As, we know that:
Change in entropy = Change in entropy of system + Change in entropy of surrounding
As we are given in question, the entropy of surroundings decrease by the same amount as the entropy of the system increases.
For the given reaction to be spontaneous, the total change in entropy should be positive.
Given :
Entropy change of system = +125J/K
Entropy change of surroundings = -125J/K
Total change in entropy = Entropy change of system + Entropy change of surroundings
Total change in entropy = 125 J/K + (-125 J/K)
Total change in entropy = 0
The process is at equilibrium because the entropy change is equal to zero. So, the process is not spontaneous.
Water is the only one of these that would work by process of elimination.
<h3>Answer:</h3>
Platoic Acid
<h3>Explanation:</h3>
While naming Carboxylic Acids we know that when the Carboxylic Acid looses proton it is converted into corresponding conjugate base called as Carboxylate.
Examples:
HCOOH → HCOO⁻ + H⁺
Formic acid Formate Ion
H₃CCOOH → H₃CCOO⁻ + H⁺
Acetic acid Acetate Ion
H₅C₂COOH → H₅C₂COO⁻ + H⁺
Propanoic acid Propanoate Ion
Therefore, if the conjugate base is Platoate then the corresponding acid will be Platoic Acid means we will replace the -ate by -ic acid <em>i.e.</em>
RCOO⁻ + H⁺ → RCOOH
Platoate Ion Platoic Acid
The whole Activity , poem and paragraph is missing in the question.
Answer:
(1) Liquid A
(2) Solid A
Explanation:
Using this part of the given poem
Substances and mixtures behave differently,
During boiling and melting most especially
Boiling point of substance is fixed while mixture is not
Substance melts completely but mixture does not
The boiling point of the Pure substance remain fixed after reaching its boiling point this is shown by Liquid A
Solid A is melting completely so Solid A is a pure substance.
