Lattice energy - - The enthalpy change when 1 mole of ionic compound is formed from its gaseous ions under standard conditions - It is the energy given out when ions of opposite charges comes together to form an ionic lattice Lattice energy is endothermic or exothermic? - - It is always exothermic because bonds are being formed (ionic bond) between oppositely charged ions, not broken Equation showing the formation of NaCl lattice - - Na^+(g) + Cl^-(g) > NaCl(s) The state of the opposite...

MCAT General Chemistry (Princeton Review) Questions and Answers | Latest Update | 2024/2025 | Already Passed What is the role of a Lewis acid and a Lewis base in a chemical reaction? A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. They interact to form a coordinate covalent bond where the base donates an electron pair to the acid. How does the concept of bond enthalpy relate to the strength of a chemical bond? Bond enthalpy (or bond dissoci...
