thermodynamics

Question 1

what is enthalpy of hydration

Answer 1

the enthalpy change when one mole of gaseous ions is dissolved in water to form one mole of aqueous ions under standard conditions

Question 2

what is covalent character and how does it occur

Answer 2

occurs in ions when two joined ions have varying sizes or charges so charge distribution is uneven
