How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated

-

6.4 moles

Explanation:-

The word 'Anhydrous' means no water of crystallization is present in the chemical formula.

The formula for anhydrous copper sulphate is CuSO4.

The word 'Hydrated' means water of crystallization is present in the chemical formula.

The formula for hydrated copper sulphate is CuSO4.5H2O

The balanced chemical equation for this reaction is

CuSO4.5H2O --> CuSO4 + 5 H2O

From the equation we can see that

1 mole of CuSO4.5H2O gives 1 mole of CuSO4

∴ 6.4 moles of CuSO4.5H2O gives 6.4 moles of CuSO4

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

i believe the answer is true.
