The standard enthalpy change of formation of sodium (ΔHf°) is 0 kJ/mol. This means that the enthalpy change when 1 mole of sodium is formed from its elements in their standard state is zero.
The standard molar entropy of solid sodium sulfate (Na2SO4) is 115 J/mol·K.

Sodium sulfate.
No, sodium sulfate does not contain iodine. Sodium sulfate is composed of sodium, sulfur, and oxygen atoms, while iodine is a separate chemical element.
The answer to this question must be in Perry's Chemical Engineering Handbook, or the CRC Handbook of Chemistry and Physics, or the JANAF Thermochemical Tables... I just don't have mine handy right now, and I need the same answer for a homework problem. These books have the enthalpy of formation for a myriad of substances. Go to your nearest library and look it up! Wink

Yes, it is an intensive property.
The ionisation enthalpy of potassium is lower than that of sodium.
The standard molar entropy of solid sodium sulfate (Na2SO4) is 115 J/mol·K.
The lattice enthalpy of sodium chloride is 789 kJ/mol.
sodium sulfate
Na2SO4 is sodium sulfate sometimes called disodium sulfate. Sodium sulfate from a natural source is known as thenardate and was formerly called Glauber's Salt.
Sodium sulfate.
Na2SO4 is the chemical formula for sodium sulfate.
The chemical formula of sodium sulfate is Na2SO4.
When sodium hydroxide and sodium sulfate react, they form sodium sulfate and water. The chemical equation for this reaction is: 2 NaOH + Na2SO4 -> 2 Na2SO4 + H2O.
