On December 1, 1783, Jacque Charles became the first human topilot a non-tethered hydrogen balloon. He flew the balloon for 15miles and stayed in the air for a total flight time 45 minutes. The balloon was made of silk coated with a think layer of naturalrubber and had a diameter of 27 ft. He generated the hydrogen gasneeded to lift the balloon by mixing a large amount of iron with aquepus sulfuric acid. If used 1000lbs. of iron and excess sulfuricacid, how many liters of hydrogen gas were made? Fe(s) + H2SO4(aq) > FeSO4(aq) + H2(g)
