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

Dalton theory is based on atomic theory and now is known as formula weight whereas Gay-Lussac measured the volume of the gases.

Now, Dalton verified the law of multiple proportions theory but he was not able to state the change in volume from 4 to 2 in case of nitrogen and hydrogen (at constant temperature and pressure) whereas Gay-Lussac verified the results and prepared gases theory by combining volumes of gases.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

its going to be mutualism cuz they both benefit from the relationship.
