Given: Va= 25.0 mL of 0.250M nitric acid is the sample volume. 0.225M KOH is used in the buret for titration. Find: Vt of KOH needed to neutralize the acid.
1HNO3 + 1KOH → 1H2O + 1KNO3

Iknow #2 is d. i just need to know why

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.
