15. beth has two unlabeled balloons, one filled with hydrogen gas and the second filled with neon gas. she
rescarches and writes down the density of hydrogen and neon. beth also has several chambers filled with
various gases and a poster showing the densities of these gases. she has no other materials or tools
available to her to her identify the element in each balloon. the poster and beth's data are shown.
