**Gas Collection over Water in the Lab**In laboratory settings, gas produced by a chemical reaction can often be collected over water, as depicted in the accompanying sketch. This method simplifies the process of isolating and measuring the volume of gas produced.**Example Scenario:**Consider a situation where oxygen gas (\(O_2\)) is generated via a specific chemical reaction at a temperature of 40.0°C. This gas is collected over water using an apparatus similar to the one shown in the sketch. The gas volume in the collection tube reaches 109 mL.**Objective:**Calculate the mass of \(O_2\) contained within the collection tube. Round the final answer to two significant figures. Any reasonable assumptions about the reaction conditions and the nature of the gases may be applied.**Diagram Explanation:**The sketch illustrates a gas collection apparatus. - **Components:** - A flask containing a chemical reaction is connected via a tube to a collection tube filled with water. - Gas produced from the reaction displaces the water, allowing the gas to collect at the top of the inverted tube.**Labels:**- **Collected gas**: The area in the tube where the gas accumulates.- **Water**: The medium over which the gas is collected, filling the main part of the collection tube.- **Chemical reaction**: Occurs in the flask, producing the gas that travels through the tube.This method takes advantage of the gas's ability to displace water, providing an accurate measure of gas volume.

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 40.0 °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 109. mL. collected gas water chemical reaction 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.

Two students perfomed an experiment on the decomposition of hydrogen peroxide. One student was in Wisconsin where the atmospheric pressure was 0.996 atm. The other was in Colorado, where the atmospheric pressure was 0.832 atm. Both reactions were performed at the same temperature and produced the same number of moles of oxygen gas. How do the volumes of gases collected compare? Are they the same or not? Explain.
