In Exam 5 we learned about how limestone was made. Ca+2O+2H+C+2O= CaCO3 Ca(OH)2 CO2 Calcium Calcium Carbon Carbonate Hydroxide Dioxide AKA Calcite The calcium atom bonds with the carbon dioxide plus one of the oxygen atoms from the hydroxide part of the calcium hydroxide to make a molecule of calcium carbonate. The remaining oxygen atom bonds with the two hydrogen atoms to make a molecule does not dissolve in water so if forms a solid white material. Called white precipitate it falls then mixes with bones and shells at the bottom of the ocean. Then when it’s at the bottom the weight of the water crushes it making limestone. In simpler words the fish breath in the limewater (calcium hydroxide Ancient sea water) making white precipitate that falls mixes with bones and shells then make limestone.
