the ionic salt kbr is dissolved in water, much like the experiments given in the simulation. A mass of 91.0 g of salt is added to 100. g of water. Both start at a temperature of 23.0°C. AHol for KBr is 8.00 kJ/mol. Given this information calculate the final temperature (TO) Express your answer to three significant figures. View Available Hints)

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!
