coal is made out of peat which is decaying plant matter, and pressure. After billions of years coal is formed.
it is black, used for burning to create energy, lumpy, cheap, and produces lots of carbon when burned
Black, combustible, fossil fuel.
Bituminous coal is a non-foliated rock. It is a sedimentary rock formed from the compaction and alteration of plant material, which does not exhibit any foliation or layering like metamorphic rocks do.
as black as coal means that something is very very very very dark black
Bituminous coal is a type of coal that is often referred to as soft coal, containing a high amount of carbon and volatile matter. It is widely used for electricity generation and in the production of steel due to its high heat output and relatively low sulfur content.
To find the density of a piece of coal, you would first measure the mass of the coal using a scale. Next, you would measure the volume of the coal using displacement method or a caliper. Finally, divide the mass of the coal by its volume to calculate the density, which is typically expressed in g/cm³ or kg/m³.
Decomposed organic material .
Coal is a black, combustible sedimentary rock that is mainly composed of carbon. It is brittle, typically black or brown in color, and has a wide range of heating values depending on the type of coal. Coal can leave a powdery residue when handled and may have a distinct odor when burned.
Coal is a hard end sedimentary rock that is brown and kind of black.
Black, combustible, fossil fuel.
You would have a coal fire, it is a type of coal

Coal is a fossil fuel.
Perhaps this way. I am not an expert. Green feels like grass, Blue is cold ice, Red is hot coal, Black is heavy coal, White is light silk, Pink is fluffy cotton, Brown is the bark of a tree.
The chemical that you describe looks like slightly hydrogenated coal. No petroleum derived hydrocarbon would have so few hydrogen atoms. With the addition of another 12 hydrogen atoms, you would have a hexane molecule.
Bituminous coal is a non-foliated rock. It is a sedimentary rock formed from the compaction and alteration of plant material, which does not exhibit any foliation or layering like metamorphic rocks do.
Why would it be "coal?" Coal is not a jewel or gem, nor is it glamorous in the least.
