Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Suppose the CO₂ gas evolved by a certain chemical reaction taking place at 50.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 55.7 mL. g x10 X S Sketch of a gas-collection apparatus Calculate the mass of CO₂ that is in the collection tube.

a 2.802g sample of an unknown pure metal (M) is added to a 0.2 L solution of 2 mol/L H2SO4(aq). The metal reacts with the acid until the metal is completely gone to form M3+(aq) ion in the solution and produces hydrogen gas that is collected. The hydrogen gas that is collected over water that is isolated from the reaction has a volume of 0.82 L at 25 degrees Celsius and a total pressure of 704.0 mmHg. How many moles of H2(g) are produced? Write a balanced equation for the reaction of M with H2SO4(aq). What is the identity of metal M?

According to Dalton, the pressure exerted by a gas inside a container is proportional to the number of molecules of that gas.  If 4.00 x 1023 molecules of N2 and 2.00 x 1023 molecules of O2 are mixed in a container they exert a total pressure of 1686 torr.  What portion of that pressure (in torr units) is exerted by the N2?  Report answer to four significant figures in decimal notation. _____________________ torr,   What portion of that pressure (in torr units) is exerted by the O2?  Report answer to four significant figures in decimal notation. ____________________ torr
