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. collected gas chemical water reaction Suppose the CÓ gas evolved by a certain chemical reaction taking place at 30.0 °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 142. mL. Sketch of a gas-collection apparatus Calculate the mass of CO 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. Og

What effect will this have on the volume of hydrogen collected? What effect will this have on the calculated mass of magnesium? a balanced chemical equation.

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?

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 55.0 °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 129. mL. g x10 177 Sketch of a gas-collection apparatus x collected gas Calculate the mass of CO₂ that is in the collection tube.

A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 109. kPa. The piston is now pulled up, expanding the gas, until the gas has a final volume of 63.0L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.
