The iodide (i2) content of a commercial mineral water was measured by two methods that produced wildly different results.6 method a found 0.23 milligrams of i2 per liter (mg/l) and method b found 0.009 mg/l. when mn21 was added to the water, the i2con- tent found by method a increased each time that more mn21 was added, but results from method b were unchanged. which of the terms to understand describes what is occurring in these measurements? explain your answer. which result is more reliable?

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!
