Answer:
286 J/K
Explanation:
The molar Gibbs free energy for the vaporization (ΔGvap) is:
ΔGvap = ΔHvap - T.ΔSvap
where,
ΔHvap: molar enthalpy of vaporization
T: absolute temperature
ΔSvap: molar entropy of the vaporization
When T = Tb = 64.7 °C = 337.9 K, the reaction is at equilibrium and ΔGvap = 0.
ΔHvap - Tb . ΔSvap = 0
ΔSvap = ΔHvap/Tb = (71.8 × 10³ J/K.mol)/ 337.9 K = 212 J/K.mol
When 1.35 mol of methanol vaporizes, the change in the entropy is:
Answer: Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.

Answer:
The volume of 6 M NaOH is 5.5 ml
Explanation:
The equation of reaction is
C₃H₅(C₁₇H₃₅COO)₃+3 NaOH → C₃H₅(OH)₃+3 C₁₇H₃₅COONa
The molar mass of triglyceride M is 890 g/mole, so in 10.0 g of its are
From the equation of reaction one mole of triglyceride reacts with three moles of NaOH.
So,
the quantity moles of NaOH which actually needed to react is:
0.011 x 3=0.033 moles.
These quantity moles of NaOH are consist in
∴The volume of 6 M NaOH is 5.5 ml
