Coal tar is a complex mixture of organic compounds derived from the distillation of coal. It contains various hydrocarbons, phenolic compounds, and heterocyclic compounds. The specific composition of coal tar can vary depending on the source and method of production.
there is no chmeical formula in the snake venom.
The melting point of coal can vary depending on the type and composition of the coal. Typically, the melting point of coal ranges from 2100 to 2400 degrees Fahrenheit.

A mineral must have a definite chemical composition and a crystalline structure, neither of which apply to coal.
Coal is not considered pure because it is typically composed of a mixture of different organic and inorganic materials. The composition of coal can vary depending on the type and age of the coal deposit.
The flash point of coal can vary depending on the type and composition of the coal, but it is generally between 450-600°C (842-1112°F).
Carbon is the primary element present in coal, making up a significant portion of its composition.
Yes, coal can have a shiny or lustrous appearance. It may exhibit a metallic or glassy sheen depending on its carbon content and 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.
The main components of coal are carbon, hydrogen, oxygen, nitrogen, and sulfur. The composition and amount of each component vary depending on the type of coal, with carbon being the dominant element in coal.
