Type the correct answer in the box. express the answer to two significant figures.
given:
n2 + 3h2 → 2nh3
bond bond energy (kj/mol)
n≡n 942
h–h 432
n–h 386
use the bond energies to calculate the change in enthalpy for the reaction.
the enthalpy change for the reaction is
kilojoules.

Agas can holds 2.0 gal of gasoline. what is this quantity in cubic centimeters?

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.
