Data: enthalpy change of atomisation for Na(s) +107kJmol–1 first electron affinity of oxygen –141kJmol–1 second electron affinity of oxygen +798kJmol–1 enthalpy change of formation of Na Web19 feb. 2024 · So, when 1 mole of sodium chloride crystals are dissolved in an excess of water, the enthalpy change of solution is found to be +3.9 kJ mol-1. The change is slightly endothermic, and so the temperature of the solution will be slightly lower than that of the original water. Thinking about dissolving as an energy cycle
WebSodium sulfide (Na2S) has a melting point of 1223 K. Predict the type of bonding in sodium sulfide and explain why its melting point is high. Type of bonding Explanation . Ionic oppositely charged ions/+ and - ions or particles ions attract strongly OR strong/many (ionic) bonds must be broken State the type of bonding involved in silver. WebIn one definition, the lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. This definition causes the value for the lattice energy to always be positive, since this will always be an endothermic reaction. For sodium chloride, the solid is more stable than the gaseous ions by 787 kJ mol-1, … How is lattice energy estimated using Born-Haber cycle?
