A mineral is a naturally occurring, inanimate object with a highly specific chemical composition. Coral is the fossilized remnants of a living aquatic creature and thus does not qualify.
Coral is also not considered a mineral since it is organic. All real minerals are inorganic.
ANS: 3By definition #1: coral is not a mineral because it is not homogeneous, it does not have a definite chemical composition nor is it crystalline.
Dead carbonate coral skeletons can meet definition #3 for being a mineral since they are composed of inorganic matter. The skeletons are composed predominately of calcium carbonate. Not all carbon compounds are organic. Carbonates are one class of chemicals that are considered inorganic even though they contain carbon. Carbon dioxide gas is also considered to be inorganic.
1. A naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure, color, and hardness.
2. Any of various natural substances, as:
3. A substance that is neither animal nor vegetable; inorganic matter.
4. An inorganic element, such as calcium, iron, potassium, sodium, or zinc, that is essential to the nutrition of humans, animals, and plants.
5. An ore.
No. Mercury is a liquid, it lacks a crystal structure and technically is not really a mineral but a mineraloid
Because it is a manmade sediment.

Liquid water is not considered a mineral because it is not a solid. But solid water--ice, is considered a mineral because it is a solid with a crystal form.
Ice forms a glacier and therefore it is considered a mineral.
the red part in a thermometer is mercury.

No, because the metal mercury which is a liquid at room temperature, does not occur naturally in the "native" state. It is usually found as Cinnabar (Mercuric oxide). It is an element.
Mercury comes from several types of mineral deposits world wide, but the most common type of mineral is called cinnabar. Cinnabar is mercury chemically bound to sulfur, i.e. HgS. Heating this mineral causes the sulfur to combine with oxygen creating sulfur dioxide, SO2, as a gas. (The gas is now considered a pollutant.) What remains is the mercury. Although mercury is a relatively rare element, there are dozens of sites around the world where it is actively mined.
maybe
it is mercury because mercury is the most hazardous mineral fiber

Minerals containing mercury are solid salts of the metal (e.g. cinnabar, corderoite, livingstonite, vermilion, calomel). The liquid metal must be extracted from these ores by smelting, as it does not exist in the metallic form naturally.
Liquid water is not considered a mineral because it is not a solid. But solid water--ice, is considered a mineral because it is a solid with a crystal form.
Cinnabar is a mercury mineral - HgS.
Quartz is a mineral.
Water as a solid, in the form of ice, is considered a mineral when it is naturally occurring. Ice in snow banks is considered a mineral but ice cubes you make in your freezer are not a mineral.
