Question

What refinements had to be made in Dalton's atomic theory to account for Gay-Lussac's results on the combining volumes of gas?

Answer 1

So I know that Dalton thought water contains only one hydrogen and one oxygen ( OH ). But he was the one that created the law of multiple proportions. He thought that nature should be as simple as possible so he wrote water as OH. But then Lussac did the experiment carefully and found out that the water formula is H2O. So how do I answer this question?
