Propionoic acid, c3h6o2, reacting with methanol, ch4o, will produce c4h8o2 and water. if 70.0 g of propionoic acid and 60.0 g of methanol are reacted together, which one will be the limiting reactant?
c3h6o2 + ch4o → c4h8o2 + h2o

The diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

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.
