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.

1. list three scientific reasons cockroaches may fly.

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?

Consider this initial-rate data at a certain temperature for the reaction described by
