... Hence, at 450 °C, 108.24 kJ is evolved for each mole of the equation i.e 108.24 kJ is evolved per mole of nitrogen which reacts. Since, for a gas, volume ∝ number of moles, the 1:3 mixture is in the stoichiometric amount. At 0 °C and 1 atm pressure, 1 mole occupies 22.4 dm3. Thus, the total amount o ...

... The energy of ionic bonds can be calculated using Coulomb’s Law, where Q = the charge of each ion, and r = distance between ions (nm): (Negative answer = attraction, positive answer = repulsion) E = 2.31x10-19 J nm (Q1Q2/r) For example, the energy of a NaCl bond, given r = 0.276nm, would be: 2.31x10 ...
