Bituminous coal is relatively soft and dull, as opposed to anthracite which is hard and shiny. Anthracite is also much more dense and pure. Because of its purity (can be up to 98% carbon), Anthracite burns a very hot, smokeless flame.
Coal, particularly anthracite coal, is almost pure carbon.
Acids in their pure state, that is, not disolved in water, are referred to as anhydrous, meaning "without water". Ray
Bituminous Coal exists in the geological area known as The Pittsburgh Coal Seam-- an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Though mined since the days of Native American Indians, and heavily mined since 1800, it is estimated there is still enough coal in this large seam to last millions of years. Bituminous coal is a soft coal and was well-suited to burning in factories and homes, and thus, held more demand and higher price.
Yes indeed it is hard its hard but not not really really hard.

Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.

yes it is. a dachshund is also more commonly referred to as a "wiener dog"
No.It is sedimentary, however anthracite is considered metamorphic. Graphite (chemically pure carbon) can be found in igneous rocks.
Peat is decayed vegetation probably thousands of years old but which has not been converted to coal. Lignite is called brown coal, again vegetable matter that has not become true coal. Anthracite is a very pure form of coal much valued for steam engines.
Factors inhibiting non-doctrinal research include lack of funding, limited resources, institutional biases towards doctrinal research, and a lack of recognition or value placed on non-doctrinal methodologies in certain academic circles.
The name of hard carbon is Diamond. If you are speaking of coal then it would anthracite. Carbon has another allotropic form which is graphite.

Pure carbon is one kind of element, which is one kind of pure substance.There are several materials that are formed from pure carbon, including:graphiteDiamond. Diamond is elemental carbon that has been exposed to high pressure and temperature for prolonged periods to form the crystal diamond carbon nanotubes(See the links below for other allotropes of carbon)Anthracite coal is nearly pure carbon.
