Document Summary
R = 8. 314 j/molk = 0. 08206 l atm/molk. 1 atm = 760 torr = 101. 325 kpa. There are 9 pages in this quiz including the cover page and the periodic table. Check and make sure you have answered each question before handing in the quiz. The quiz is out of 35 points, but a maximum of 40 points is possible. In 1783, the french physicist jacques charles supervised and took part in the first human flight in a hydrogen balloon. Such balloons rely on the lower density of hydrogen relative to air to give them their buoyancy. In charles" balloon ascent, the hydrogen was produced (together with iron (ii) sulfate) from the action of aqueous sulphuric acid on iron filings. Write a balanced chemical equation for this reaction. What volume of hydrogen is produced at 300. K and a pressure of 1. 0 atmosphere when 3. 00 x 103 g of sulphuric acid is consumed in this reaction? (1) (4) (4) (1)
