Answer : The correct option is, (b) +115 J/mol.K
Explanation :
Formula used :
where,
= change in entropy
= change in enthalpy of vaporization = 40.5 kJ/mol
= boiling point temperature = 352 K
Now put all the given values in the above formula, we get:
Therefore, the standard entropy of vaporization of ethanol at its boiling point is +115 J/mol.K
You would have to evaporate the water to get just the sugar
A coordination complex consists of a central atom or Jon, which usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligand or complexing agents
Answer:
1. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will continue to move across the membrane in both directions.

In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. In this experiment, aphenolphthalein<span> color indicator will be </span>used<span>.
</span>Phenolphthalein<span> is colorless in acidic solutions and pink in basic solutions.
