Calcium carbonate Formula - Calcium carbonate Uses, …

Formula and structure: The chemical formula of calcium carbonate is CaCO 3 and its molar mass is 100.1 g/mol. It is a salt made of the bivalent calcium ion (Ca 2+) and the bidentate carbonate anion (CO 3 2-), in which the carbon is attached to two oxygen atoms through single bonds and one oxygen atom through a double bond.

Difference Between Boiling Point and Melting Point

2015/8/31· Main Difference – Boiling Point vs. Melting Point Melting point and boiling point both describe temperatures at which phase changes occur in substances.The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour …

why does calcium fluoride have a high melting point - …

Both are diatomic with simple molecular structures. Both have van Der Waals forces of attraction between molecules but since Br2 is larger than F2 so has more electrons, these forces are stronger in Br2 so the melting point is greater for Br2 than F2. (Original post by Endany keroi)
