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.
What else can I help you with?
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.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
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 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.
Do coal have definite chemical composition?
Coal does not have a definite chemical composition; it is a complex mixture of organic compounds, primarily carbon, along with varying amounts of hydrogen, sulfur, oxygen, and nitrogen. The composition can significantly vary based on the type of coal (such as anthracite, bituminous, sub-bituminous, or lignite) and the geological conditions under which it formed. Additionally, impurities like minerals and moisture content can also influence its overall composition. As a result, coal is classified more by its properties and rank rather than a fixed chemical formula.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
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 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?
C_0.47 H_0.42 S_0.004 N_0.009 O_0.045 Ash_0.014
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.
