BALOCHISTAN MDCAT PAPER 2022 ( PART 12 ) 1. Bein-Haber cycle is used to calculate? Enthalpy of combustion Lattice energy of ionic compounds Lattice energy of covalent compounds Enthalpy of ionization 2. Why do electrons have opposite spins when they are in the same orbital? This condition reduces friction This condition results in less repulsion and opposite magnetic fields This condition creates more energy This condition results in zero magnetism and removes the charge of the electron 3.
