9) Some cracker tins include a glass vial of drying material in the lid. This is often a mixture of magnesium sulfate and
cobalt chloride. As the mixture absorbs moisture to form hydrated compounds, the cobalt chloride changes from blue-
violet CoCl2 • 2H20 to pink CoCl2 • 6H20. When this hydrated mixture becomes totally pink, it can be restored to the
dihydrate form by being heated in the oven. Write a chemical equation and a word equation for the reactions that occur
when this mixture is heated.

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!
