The tank shown below contains helium , nitrogen , and oxygen gas and it has a volume of 425 L. Each marker in the container represents a mole of gas in the mixture . The container is at room temperature 25 C .

Part a. Count the number of moles of helium in the sample . Repeat for nitrogen and oxygen .
Part b. Determine the mole fraction of each of the three gases.
Part c. Calculate the pressure of each gas. Use the volume and temperature listed above for each calculation.
Part d. Find the total pressure inside the container by adding the partial pressure for each gas.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
