Aliphatic hydrocarbons are straight-chain or branched-chain molecules that contain only carbon and hydrogen atoms. Aromatic hydrocarbons are ring-shaped molecules that also contain carbon and hydrogen atoms.<\/p>\n<p>Coal is a solid fossil fuel formed when plant material was buried and subjected to intense heat and pressure over millions of years. The resulting coal is a mixture of carbon, hydrogen, oxygen, and sulfur atoms. Coal is classified into four types: lignite, subbituminous coal, bituminous coal, and anthracite. Lignite is the lowest grade of coal and has the highest moisture content. Anthracite is the highest grade of coal and has the lowest moisture content.<\/p>\n<p>Petroleum is commonly called liquid gold because it is a valuable resource that is used to produce gasoline, diesel fuel, jet fuel, and other products. Coal is also a valuable resource that is used to produce electricity and steel.<\/p>\n<p>Statement 1 is correct because petroleum is a major source of aliphatic hydrocarbons. Statement 2 is correct because coal is a source of aromatic hydrocarbons. Statement 3 is incorrect because petroleum is not commonly called liquid gold.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[637],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Study the following statements. 1.
