The lattice energy of kbr is 671.0 kj/mol and its heat of solution is 19.9 kj/mol. calculate the hydration of energy of kbr(s).

We are given with
Lattice energy = 671.0 kJ/mol
Heat of solution = 19.9 kJ/mol

Heat of hydration = lattice energy + heat of solution
Heat of hydration = 671.0 kJ/mol + 19.9 kJ/mol
Heat of hydration = 690.9 kJ/mol

Ithink that the use of creativity in the sciences entails that one produce something out of nothing or from another thing. with this, i think that the he wrote down his results as four parts of the atomic theory is the manifestation of the  creativity of john dalton.
