What type of product is coal?
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen….Composition.
Is coal a natural product?
Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (e.g., dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes.
What is coal an example of *?
Coal is an example of Sedimentary rocks. Coal is a biochemical sedimentary rock because coal is formed from organic matter or sediment that comes from biological processes. Coal is typically found near swampy areas, or areas where sediment has little contact with oxygen.
Is coal a compound?
-Coal is made up of more than one compound so it is a mixture. -Alcohol is made up of carbon, hydrogen, and oxygen so it is a compound. Note: Metals, non-metals, and metalloids are the classification of elements. Compounds are two types: organic compound and an inorganic compound.
Is coal nonrenewable or renewable?
Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
Which is not a coal product?
carbon dioxide is not a coal product.
Is coal a metallic?
Coal is non-metal. It is an amorphous form of Carbon. Coal is a substance formed from decayed plants and animals. Therefore, coal is not considered a mineral.
How is coal produced?
Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.
What are coal uses?
Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Is coal heterogeneous or homogeneous?
When we look into the composition of coal, coal contains carbon, hydrogen, sulfur, volatile impurities, and moisture. Also, the appearance is not the same throughout. As a result, coal is not a homogenous mixture, but it is a heterogeneous mixture.
