Calcium Carbonate - CaO3
Density | * 2.71 g/cm3 (calcite) * 2.83 g/cm3 (aragonite) | Exact mass | * 100.0869 g/mol | Molecular Formula | * CaO3 | Melting point | * 825 °C (calcite) * 1339 °C (aragonite) | Boiling point | * Decomposes | Acidity | * 9.0 | Flash point | * Non flammable | Crystal structure | * Trigonal | Other names | * Limestone, Marble, Chalk, Calcite and pearl. |
Calcium carbonate is a chemical compound with the chemical formula CaCO3. It is one of the most common substances found in rock in every part of the world, and is the main ingredient in shells, marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the top cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but extreme use can be risky.
Word meanings
Antacid: It is any substance which neutralizes stomach acidity, usually a base or a basic salt.

Amethyst
Silicon dioxide - SiO2
Density | * 2.634 g/cm3 | Exact mass | * N/A | Molecular Formula | * SiO2 | Melting point | * 1650(±75) °C | Boiling point | * 2230 °C | Acidity | * N/A | Flash point | * Non-Flammable | Crystal structure | * Explanation bellow, after main. | Other names | * Silica, Quartz |
The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness for centuries. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. Silica is the riches mineral in the Earth's crust. The crystal structure of Silicon Dioxide changes as the compound heats up. The original structure is trigonal, but when it heats up to 573C°, its structure
