Aflask containing solid ammonium chloride becomes colder as water is added and the salt dissolves. is the magnitude of the lattice energy of nh4cl larger or smaller than the combined hydration energy of the ions?

The lattice energy of the solid ammonium chloride is larger than the combined hydration energy of the ions.  

Further Explanation:

lattice energy:

The cross section vitality of a crystalline strong is a proportion of the vitality discharged when particles are consolidated to make a compound. It is a proportion of the firm forcess that predicament particles. Cross section vitality is significant to numerous viable properties including dissolvability, hardness, and instability.  

lattice energy increase:

This model underlines two primary factors that add to the cross section vitality of an ionic strong: the charge on the particles, and the span, or size, of the particles. The impact of those variables is: as the charge of the particles builds, the grid vitality increments. as the size of the particles expands, the cross section vitality diminishes.  

lowest lattice energy:

In both CaO and MgO, the charges are +2 and - 2, so the decision is between these two oxides. The littlest particles will most likely get nearest to one another. They will havethe littlest separation among focuses and will have the biggest cross section energies.The littlest particles are at the highest point of the Periodic Table.  

higher lattice energy:  

The bond between particles of inverse charge is most grounded when the particles are little. The cross section energies for the salt metal halides is in this manner biggest for LiF and littlest for CsI, as appeared in the table beneath. The ionic bond ought to likewise end up more grounded as the charge on the particles increases.
