15.0 mL of 0.50 M HCl is added to a 100.-mL sample of 0.314 M HNO, (Ka for
HNO2,=4.0 x 10-4). What is the equilibrium concentration of No2 ions?

Harvey mixes two liquids. which observation of the new mixture most likely indicates a precipitate is forming?

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.
