Structure:
- Crystal structure: Trigonometrical
- Percent Composition by mass: 64%
- Bond: covalent
- reacts strongly with acids, and reactions form carbon dioxide.
- releases carbon dioxide when heated to above 840°C and forms calcium oxide
- forms soluble calcium bicarbonate when it reacts with water that is saturated with carbon dioxide.
- carbon bicarbonate - Ca(HCO3)2 - is essential to the erosion of carbonate rock
