An unknown, clear liquid is given to you in a beaker. you transfer the liquid from the beaker to a clean, empty test-tube, and begin to heat it. after a while, you see vapours (which on further analysis you discover are vapours of water) rising from the test-tube, and pretty soon, all that's left are a few crystals of salt stuck to the edges!

was that liquid an element, compound or a mixture?

Write the chemical formula for a compound that is made of an element from group 1 and an element from group 17

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!
