Asked in Chemistry
How does lattice energy differs from bond enthalpy?
Bond enthalpy is the energy required to break a chemical bond whereas lattice energy is the enthalpy of formation of one mole of an ionic compound from gaseus ions under standard conditions. ...
Asked in Definitions
What is the definition of enthalphy?
The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound. It is usually defined as the enthalpy of formation of the ionic compound from gaseous ions and as such is invariably exothermic. The concept of lattice energy has initially been developed for rocksalt-structured and sphalerite-structured compounds like NaCl and ZnS, where the ions occupy high-symmetry crystal lattice sites. In case of NaCl, the lattice energy is the energy released by the reaction ...

What are the energy changes involved in the formation of NaCl?
The standard enthalpy of formation, for solid NaCl: -411,12 kJ/mol at 25 0C. ...
Asked in Salt (Sodium Chloride)
What is the enthalpy of formation for NaCl aqueous?
This value is +3,87 kJ/mol at 25 0C.
Asked in Chemistry
In a sample of sodium chloride (NaCl) the sodium and chloride ions are arranged into .?
Sodium chloride forms a lattice structure.
Asked in Elements and Compounds
Can lattice space of NaCl crystal be determined by diffraction experiment with sodium yellow light?
No. The ions of a salt as simple as NaCl are smaller than the wavelength of any visible liqht; X-rays are needed to determine lattice spacing. ...
