[amp_mcq option1=”Chlorine” option2=”Oxygen” option3=”Phosphorus” option4=”Sulphur” correct=”option1″]<\/p>\n
The correct answer is: A. Chlorine<\/strong><\/p>\n Chlorine is a pale yellow-green gas at standard temperature and pressure. It is an extremely reactive element and is the second most abundant halogen. Chlorine is used in a variety of industrial processes, including the production of plastics, pesticides, and bleach. It is also used in water treatment to disinfect drinking water.<\/p>\n Oxygen is a colorless, odorless, tasteless gas that is essential for life. It is the most abundant element in the Earth’s atmosphere, making up about 21% of the air. Oxygen is also found in water and in the Earth’s crust. It is used in a variety of industrial processes, including the production of steel, glass, and paper. It is also used in medical applications, such as in the treatment of asthma and other respiratory problems.<\/p>\n Phosphorus is a non-metallic chemical element that is found in nature in a variety of forms, including white phosphorus, red phosphorus, and black phosphorus. White phosphorus is a waxy, white solid that is highly flammable. Red phosphorus is a red, amorphous solid that is less flammable than white phosphorus. Black phosphorus is a black, crystalline solid that is the most stable form of phosphorus. Phosphorus is used in a variety of industrial processes, including the production of fertilizers, pesticides, and matches. It is also used in medical applications, such as in the treatment of cancer.<\/p>\n Sulphur is a non-metallic chemical element that is found in nature in a variety of forms, including elemental sulphur, sulfur dioxide, and sulfuric acid. Elemental sulphur is a yellow, crystalline solid that is found in deposits around the world. Sulfur dioxide is a colorless, odorless gas that is produced when sulfur is burned. Sulfur dioxide is also a major component of acid rain. Sulfuric acid is a strong, corrosive acid that is used in a variety of industrial processes, including the production of fertilizers, detergents, and batteries.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Chlorine” option2=”Oxygen” option3=”Phosphorus” option4=”Sulphur” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[],"class_list":["post-23816","post","type-post","status-publish","format-standard","hentry","category-chemistry","no-featured-image-padding"],"yoast_head":"\n
