35. While modern blimps contain helium to create lift, the Hindenburg airship that famously caught fire and crashed on May 6, 1937 in flight from Germany to the United States was filled with 200,000,000 L of hydrogen gas. a. Assuming STP conditions, how many times less dense is hydrogen gas than helium gas? b. Given that many construction materials were quite heavy at the time, why might it have been advantageous to use hydrogen instead of helium in the airship? C. Based on your understanding of chemical reactivity and the periodic table, why is hydrogen a much more dangerous choice than helium for use in airships?
