Not sure if this is what you’re asking, but:
The particles would get closer and closer together and move slower and slower. :)
Answer:
5.04 kJ
Explanation:
We are given the enthalpy of fusion of methanol as 3.16 kJ per mol of methanol. Thus, what we need is to determine is the number of mol in 25.4 g of methanol and multiply by this enthalpy.
mol methanol = mass / MW CH₃OH = 25.6 mol / 16.04 g/mol = 1.60 mol
ΔH = 1.60 mol x 3.16 kJ/mol = 5.04 kJ
The indicator, phenolphthalein is added to the analyte as an indicator in acid–base titrations.
Phenolphthalein is a color changing indicator for acid base titrations.
Titration is a quantitative technique used to find concentration of an unknown solution(analyte ) from a solution of known concentration. which is the titrant.
Now the procedure is set up that, the titrant is in the burette and added to the analyte with known volume)in a conical flask in the presence of an indicator till the endpoint of the reaction.
This is marked by a sharp change of color to explain the point when the titrant neutralizes the analyte solution.(phenolphthalein is colorless in acidic solutions but turns pink in basic solutions).
