The balloons below are filled with helium gas. Which of the balloons best represents the diffusion of helium gas within the ballloon
and why?
Balloon B because Helium is a dense gas that will collect at the bottom of the balloon.
Balloon A because the gas particles will only take the shape of the container and put pressure on
the walls.
Balloon D because gas particles are less dense and will make the balloon float.
Balloon C because gas particles diffuse to take the shape and volume of their container.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
