Is Crushing Rock Crystals A Chemical Or Physical Change From Canada

Nov 22, 2021

Nov 21, 2019 A chemical precipitate is a chemical compound—for instance, calcium carbonate, salt, and silica—that forms when the solution it is dissolved in, usually water, evaporates and leaves the compound behind. This occurs as water travels through Earth’s crust, weathering the rock and dissolving some of its minerals, transporting it elsewhere
