In the reaction 2h2 + o2 → 2h2o, what coefficient should be placed in front of o2 to balance the reaction? a) 1 b) 2 c) 3 d) no coefficient is needed

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.
