Eddie experimented to find out which freezes at a lower temperature, distilled water or salt water. The steps he used in his experiment are shown below.
1Fill one beaker with 250 mL of room-temperature distilled water
2Fill another beaker with 250 mL of room-temperature salt water
3Measure the mass of the liquid in both beakers
4Place both beakers in a freezer
Observe the temperature at which the liquids freeze

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
