Coal is mostly carbon, but it has some other elements in it, notably sulfur, hydrogen, oxygen and nitrogen. The actual molecular structure varies; there is no fixed "formula" for the chemistry of coal. Use the link below to read more and see a typical molecular representation of a bit of coal. Note the complexity and variation suggested by that diagram.
Coal is primarily composed of carbon, along with varying amounts of hydrogen, sulfur, oxygen, nitrogen, and other elements. The exact composition of coal can vary based on its type (such as lignite, bituminous, or anthracite) and source region. Additionally, impurities like ash and moisture are also present in coal.

Is burning coal in a furnace a chemical change?
Yes, burning coal in a furnace is a chemical change. During combustion, the coal undergoes a chemical reaction with oxygen to produce heat, carbon dioxide, and other byproducts, resulting in a change in the chemical composition of the coal.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Is mining coal a physical or chemical change?
Mining coal is a physical change because the act of extracting coal from the earth does not alter its chemical composition. The coal remains chemically the same before and after the mining process.
Chemical formula coal?
The chemical formula of coal can vary depending on its composition, but a general formula is approximately C135H96O9NS. Coal is primarily composed of carbon, with smaller amounts of hydrogen, oxygen, nitrogen, and sulfur.
Is burning coal a chemical or physical reaction?
Burning coal is a chemical reaction because it involves a chemical change in the coal's composition, transforming it into new substances like carbon dioxide and ash.
Is burning coal in a furnace a chemical change?
Yes, burning coal in a furnace is a chemical change. During combustion, the coal undergoes a chemical reaction with oxygen to produce heat, carbon dioxide, and other byproducts, resulting in a change in the chemical composition of the coal.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Why do geologist not consider coal to be a mineral?
A mineral must have a definite chemical composition and a crystalline structure, neither of which apply to coal.
Is mining coal a physical or chemical change?
Mining coal is a physical change because the act of extracting coal from the earth does not alter its chemical composition. The coal remains chemically the same before and after the mining process.
Chemical formula coal?
The chemical formula of coal can vary depending on its composition, but a general formula is approximately C135H96O9NS. Coal is primarily composed of carbon, with smaller amounts of hydrogen, oxygen, nitrogen, and sulfur.
Is burning coal a chemical or physical reaction?
Burning coal is a chemical reaction because it involves a chemical change in the coal's composition, transforming it into new substances like carbon dioxide and ash.
Is breaking coal into pieces chemical or physical change?
Breaking coal into pieces is a physical change because it does not alter the chemical composition of the coal. The coal remains composed of the same elements before and after being broken into pieces.
What is the chemical composition of bituminous coal?
Bituminous coal is primarily composed of carbon, with smaller amounts of hydrogen, oxygen, nitrogen, and sulfur. The exact composition can vary depending on the specific coal seam.
Which mineral is a cousin to a diamond of chemical composition?
The mineral is carbon: allotropes include diamond, graphite and coal.
Is bituminous coal a mineral?
Yes, bituminous coal is considered a mineral because it is a naturally occurring solid substance with a definite chemical composition and crystal structure.
What is the chemical formula for coal gas?
The chemical formula for coal gas can vary depending on its composition, but it typically contains a mixture of gases such as carbon monoxide (CO), hydrogen (H2), methane (CH4), and small amounts of carbon dioxide (CO2) and nitrogen (N2). The overall composition is usually represented as a range of percentages for each component.
Why is coal not considered to be a mineral?
While coal is composed of organic materials, it is generally not classified as a mineral because it is formed from plant matter rather than the inorganic processes that create minerals. Minerals are typically crystalline and have a specific chemical composition, which differs from the amorphous nature of coal.
