Agas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. it required 120 s for 1.0 l of the gas to effuse. under identical experimental conditions it required 32 s for 1.0 l of o2 gas to effuse. you may want to reference (pages 416 - 419) section 10.8 while completing this problem. part a calculate the molar mass of the unknown gas. (remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 l; that is, rate and time are inversely proportional.)

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!
