Solution & Hydration Enthalpy of solution The?standard enthalpy change of solution (ΔHsol?)?is the enthalpy change when?1 mole?of an ionic substance?dissolves?in sufficient water to form...
Comparing Lattice Enthalpies How accurate are lattice enthalpies? It is possible to calculate a theoretical value for the lattice enthalpy of an ionic solid. To do this you need to know the?...
Calculations Using Born-Haber Cycles Once a Born-Haber cycle has been constructed, it is possible to calculate the lattice energy (ΔHlatt?) by applying Hess’s law and rearranging: ΔHf??= ΔHa...
Constructing Born-Haber Cycles A?Born-Haber cycle?is a specific application of?Hess's Law?for ionic compounds and enable us to calculate lattice enthalpy which cannot be found by experiment ...
你知道嗎？參與EPQ項目，不僅成績好有機會降分錄取，而且還可以作為素材寫入PS。 關于PS的話， 只是大多數人缺乏科研經歷， 所以要靠EPQ填充， 但是如果你自己背提已經很多了，也可以只一句話帶過，還是可以用EPQ...
