Air bags, which act as safety devices in cars, contain solid sodium azide. on impact, the sodium azide releases
nitrogen gas, which expands the air bag. the main benefit of using a gas instead of another type is that —
a. gas molecules are subject to ionic bonding
b. the separation of gas molecules is much greater than the volume they occupy
c. gases won’t explode the bag on very hot days
d. gas molecules don’t transfer excess kinetic energy

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.
