Question

What refinements had to be made in dalton's atomic theory to account for gay-lussac's results on the combining volumes of gases?

Answer 1

The laws of the chemical combination were easily explained by the Dalton's atomic theory but Gay lussac law was not explained.

To Provide the Theoretical Justification to that that law, Berzelius gave his hypothesis named as Berzelius Hypothesis. According to this, Equal Volume of all gases contains the equal numbers of the atoms.

That was the main postulates which was added in the Dalton's atomic theory after Berzelius hypothesis and this also explains the Gay-lussac law.  

But this Failed after the Avogadro's shows his hypothesis and said that not equal volume of all gases contains equal numbers of atoms but they contains equal number of molecules.

Hope it helps.

Answer 2

Explanation:

According to this, Equal Volume of all gases contains the equal numbers of the atoms.

• That was the main postulates which was added .

• the Dalton's atomic theory after Berzelius hypothesis and this also explains the Gay-lussac law.
