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 O₂, gas evolved by a certain chemical reaction taking place at 35.0 °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 117. mL. g collected X gas water chemical Sketch of a gas-collection apparatus Calculate the mass of O₂ that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases. reaction

The balanced equation for the chemical equation is Mg+2HCl->MgCl2+H2 If the student used an excess of hcl to dissolve 0.045 grams of pure Mg ribbon, and collected the gas in a test tube over water how much H2 gas could she produce, calculate the answer in moles.
Three gases are mixed into one container. The partial pressure of gas D is 820.1 mmHg. The partial pressure of gas E is 217 mmHg. The partial pressure of gas F is 445.3 mmHg. Determine the total pressure of the gases in a different unit, atm. Do not round until you have finished the problem. 1.00 atm = 760.0 mmHg Your answer should contain one decimal place. Ex: If your answer is 4.435, you would use 4.4 Include the correct units.

An engine cylinder contains 250 mL of gas at a pressure of 1.0 atm. As the engine runs, it compresses the cylinder, reducing the volume of the gas to 25 mL. What is the new pressure of the gas at this volume?
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?
