有人能帮我解答吗？我做不出来。
3. What always occur in magnitudes of (i) the lattice energy (ii) the enthalpy change of hydration ⅲ)the solubility of the sulphates, as group II is descended ?
Lattice energy ehthalpy change of hydration solubility of sulphate
A decrease decrease decrease
B decrease increase decrease
C increase decrease increase
D increase increase decrease
6. The solybility of Group II sulphate decrease from magnesium sulphate to barium sulphate. How do the values of lattices energy and enthalpy change of hydration alter as the group is descended ?
Lattice energy enthalpy change of hydration
A less exothermic less exothermic
B less exothermic more exothermic
C more exothermic less
