water vapor>liquid water> ice is the correct order of increasing standard molar entropy.
Since water has more entropy than ice, melting is encouraged by entropy. However, ice has less energy than water, which means that energy favors freezing. The distinction between liquid water, ice, and water vapor is that each of them is a different state of matter. Ice represents the solid state, liquid water the liquid state, and water vapor the gaseous state of water. As a result, the system's entropy reduces. A vapour condensing is an exothermic process. Consequently, the environment's entropy rises. however, the environment's growth in entropy grows. Since the gas state has a higher entropy than the liquid state does, the entropy change for the vaporization of water is positive.

Answer:
2.33g of iron (iii) chloride
50.0 mL of 5.00 M of sodium phosphate
FeCl3 + Na3PO4 > Fe(PO4) + 3NaCl
mol = conc × vol = 0.5 × 50/1000 = 0.025 mol Na3PO4
from the equation:
1 mol of Na3PO4 reacts with 1 mol FeCl3 = 3 mol of NaCl
0.025 mol = x
x = 0.0025 × 3 = 0.075 mol NaCl
mass = 0.075 g × 59 g/mol = 4.425 g NaCl
i guessed all of this so i dont know i it is correct
Boil it. Kinetic energy is energy of motion and hot water moleculues move more
