Mark me as brainliest
Explanation:
It is also prepared by chemical synthesis by reacting quicklime (calcium oxide, CaO) with water to give calcium hydroxide (Ca(OH)2), which is then treated with carbon dioxide to precipitate the calcium carbonate salt. ... It has a density of 2.71 g/mL and melting point of 1,339 °C, as its calcite form.
