✅what forms when ionic oxides react with water
The energy released when ions are dissolved in water
similar to lattice energy (strength of ionic bond) - Correct
Answers ✅hydration energy
higher - Correct Answers ✅the higher the charge, the
______ the hydration energy
higher - Correct Answers ✅the smaller the ion, the _______
the hydration energy
at each end of the periodic table (groups 1A and 7A),
excluding the noble gases - Correct Answers ✅where on
the periodic table is reactivity the highest
e) Ba
strongest reducing agent = easily oxidized = lowest IE =
easiest to lose electrons
, Chem 2 Final Exam Q & As (Verified
Answers) 2026
