4) Another balloon is inflated to a volume of 1.250 L with dry hydrogen gas, at 28.0*C. The balloon is then cooled, and its volume drops to 964 m. If the pressure is unchanged, what is the hydrogen gas temperature (in "C) in the cooled balloon? Assume that no gas has been added or removed. 5) Yet another balloon is inflated to a volume of 434 cmuasing 0.141 moles of dry hydrogen gas. An additional 0.129 grams of hydrogen is then injected into the balloon at constant pressure and temperature. Calculate the new volume of the balloon (in em') 6) Hydrogen gas can be generated from the reaction between aluminium metal and hydrochloric acid: 2 Al(s) + 6 HCl(aq) - 2 AICI, (aq) + 3 H (8) Suppose that 3.00 grams of Al are mixed with excess acid. If the hydrogen gas produced is directly collected into a 850. ml. glass flask at 24.0 °C, what is the pressure inside the flask (in atm)? b. This hydrogen gas is then completely transferred from the flask to a balloon. To what volume (in L.) will the balloon inflate under STP conditions? c. Suppose the balloon is released and rises up to an altitude where the temperature is 11.2 °C and the pressure is 438 mm Hg. What is the new volume of the balloon (in L.)? Page 3 of 3
