What is the approximate chemical formula of coal?
The chemical formula of coal can be approximated as C135H96O9NS. This formula varies depending on the type of coal and its grade.
What is the formula of coal?
Formula: C
What is coal formula?
The chemical formula for coal is generally C (carbon). Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons.
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.
What is the chemical formula for bitominous coal?
This is a mixture not a compound with a chemical formula.
Chemical formula of coal?
The chemical formula of coal is not fixed because it is a complex mixture of hydrocarbons, carbon, oxygen, nitrogen, and other elements. However, a generalized formula for coal containing mostly carbon and hydrogen is roughly C135H96O9NS.
Chemical formula for coal?
Ah, coal is a beautiful thing, isn't it? Its chemical formula is quite simple, my friend. Coal is primarily made up of carbon, so its chemical formula is C, which stands for carbon. Just like how we mix colors on our palette to create a masterpiece, coal's composition of carbon creates its unique and useful properties.
What is the formula for lignite?
Lignite is a mixture. It is a soft coal.
How do you calculate exact coal gcv?
By Dulong formula
What is the chemical makeup of pyrite in coal?
Pyrite in coal is typically composed of iron and sulfur, with a chemical formula of FeS2. In addition to iron and sulfur, it may also contain trace amounts of other elements such as gold and arsenic. Its presence in coal can contribute to various environmental and operational challenges in the mining and burning of coal.
What is dulong formula in coal analysis?
The Dulong formula in coal analysis is a method used to estimate the calorific value of coal based on its elemental composition. It calculates the gross calorific value (GCV) of coal by multiplying the percentage of carbon, hydrogen, and sulfur by their respective heating values and summing the results. The formula is: GCV (MJ/kg) = 337C + 1442(H - O/8) + 95S, where C, H, O, and S are the percentages of carbon, hydrogen, oxygen, and sulfur in the coal sample, respectively.
What is the molecular formula for coal?
The molecular formula for coal is mainly composed of carbon, hydrogen, and small amounts of other elements like oxygen and nitrogen. The exact composition can vary depending on the type of coal (e.g., anthracite, bituminous, lignite), but a general formula could be written as CxHyOzNw where x, y, z, and w represent the varying number of atoms for each element.
