to isolate and measure the amount of gas produced. pose the CO₂ gas evolved by a certain chemical reaction taking place at 50.0 °C is colle apparatus something like that in the sketch, and the final volume of gas in the collection mL. ulate the mass of CO₂ that is in the collection tube. Round your answer to 2 significant reaction conditions and the nature of the gases

Which statement best describes why increasing pressure of a reaction involving gases will increase the rate of reaction? Increasing the pressure increases the surface area of the reactants. Increasing the pressure increases the kinetic energy of the reactants and will lead to more effective collisions. Increasing the pressure decreases the relative space of the reaction vessel and will lead to more collisions. Increasing the pressure increases the amount of reactants and will lead to more collisions.

Dinitrogen monoxide gas is collected at 28.0 °C in an evacuated flask with a measured volume of 30.0 L. When all the gas has been collected, the pressure in the flask is measured to be 0.290 atm. Calculate the mass and number of moles of dinitrogen monoxide gas that were collected. Be sure your answer has the correct number of significant digits. mass: g dlo mole: |mol I Don't Know Submit O 2021 McGraw Hill LLC. All Rights Reserved.

** 16. If nitrogen gas and oxygen gas are combined in a tank, they will be at the same tem- perature and fill the same volume. a) Basing your explanation on the kinetic theory of gases, as derived in Section 15.1, explain why you would find the total pressure in the tank by adding together the indi- vidual pressures of the nitrogen and oxygen acting alone. This conclusion is known as Dalton's Law of Partial Pressures. b) A 1-m³ tank contains 0.8 moles of nitrogen and 0.2 moles of oxygen at 300 K. What is the total pressure in the tank?

III. Que 1. Suppose you wanted to perform this experiment using aluminum metal. As- suming a volume of hydrogen of 65 mL, a final gas temperature of 25°C, and of aluminum, in grams, to be reacted. (Hint: Use the information about the a gas pressure of approximately 720 torr, calculate the appropriate amount hydrogen gas and work backwards. Be sure to include a balanced chemical equation for the reaction of aluminum with HCl to produce hydrogen gas.) Show your work. answer: grams Al =
