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 77.5 mL. y Sketch of a gas-collection apparatus collected gas water. chemical reaction Calculate the mass of CO₂ 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.

The pressure of a gas results from which of the following? gas particles colliding with the container walls. the sum of the volumes of the particles being larger than the container volume. gas particles colliding with each other. The temperature of a gas is a measure of which of the following? the amount of space between gas particles. the kinetic energy of the gas particles. the number of gas particles. the volumes of the gas particles.

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 CO, gas evolved by a certain chemical reaction taking place at 45.0 °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 39.5 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.

A gas storage cylinder in an ordinary chemical laboratory measures 2.5 cm wide and 10. cm high. This is the label on it. Contents: N, gas Pressure: 17.8 atm If the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder? Write your answer in liters. Round your answer to 2 significant digits. L x10

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 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 76.9mL.   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.   = g

Consider a gas sample with an initial pressure of 533 torr and a volume of 10.5 L. What is the pressure of the gas when the volume of the gas increases by a factor of 2.21, as the temperature of the gas remains constant.

5. You have oxygen gas in a balloon. At room temperature, 25°C, the balloon has a volume of 9 L. You put the balloon in the freezer that is at 0°C. Calculate the final volume of the balloon. You can assume that at all times; the balloon is at atmospheric pressure.

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 48.7mL.   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.   = g
