Explanation:
It is given that lattice energy is -701 kJ/mol.
Whereas it is known that realtion between lattice energy and radius is as follows.
Lattice energy
where, = +2, and = -2
Therefore, lattice energy of AB =
=
= -2804 kJ/mol
Thus, we can conclude that lattice energy of the salt ABAB is -2804 kJ/mol.
Answer:
Cu[NO(down arrow)3]^2
3 is a subscript and 2 is an exponent.
8moles
1 mole of N2 gives 2 moles of NH3
4 moles of N2 gives>( 4*2)/1
= 8moles of NH3
