The molecular mass of methyl ethanoate is 75.1 amuamu . Calculate the molecular mass of propanoic acid, an isomer of methyl ethanoate.

Compare and contrast physical changes with chemical changes.

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.

The three types is stress that act on earths rocks are compression, tension, and
