The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Here’s the classification of each substance:<\/p>\n\n\n\n

    \n
  1. Popcorn<\/strong> – M<\/strong> (Mixture): Popcorn is a mixture because it contains various components like kernels and possibly oil or butter.<\/li>\n\n\n\n
  2. Sugar<\/strong> – C<\/strong> (Compound): Sugar, typically sucrose (C\u2081\u2082H\u2082\u2082O\u2081\u2081), is a compound made of carbon, hydrogen, and oxygen atoms chemically bonded.<\/li>\n\n\n\n
  3. Air<\/strong> – M<\/strong> (Mixture): Air is a mixture because it consists of different gases like oxygen, nitrogen, and trace amounts of others like carbon dioxide.<\/li>\n\n\n\n
  4. Concrete<\/strong> – M<\/strong> (Mixture): Concrete is a mixture of cement, water, sand, and aggregate, all mixed together physically but not chemically bonded.<\/li>\n\n\n\n
  5. Clorox<\/strong> – C<\/strong> (Compound): Clorox is a brand of bleach that typically contains sodium hypochlorite (NaOCl), which is a compound.<\/li>\n\n\n\n
  6. Mercury<\/strong> – E<\/strong> (Element): Mercury is a pure element with the symbol Hg and atomic number 80.<\/li>\n\n\n\n
  7. Bronze<\/strong> – M<\/strong> (Mixture): Bronze is an alloy (a mixture of metals), primarily composed of copper and tin.<\/li>\n\n\n\n
  8. Wood<\/strong> – M<\/strong> (Mixture): Wood is a mixture of cellulose, lignin, water, and other substances that make up the structure of the tree.<\/li>\n\n\n\n
  9. Diamond<\/strong> – E<\/strong> (Element): Diamond is a form of carbon (C), which is a pure element.<\/li>\n\n\n\n
  10. Ink<\/strong> – M<\/strong> (Mixture): Ink is a mixture of water, pigments, and other chemicals used to provide color and consistency.<\/li>\n\n\n\n
  11. Salt<\/strong> – C<\/strong> (Compound): Common table salt is sodium chloride (NaCl), a compound made of sodium and chlorine atoms chemically bonded.<\/li>\n\n\n\n
  12. Platinum<\/strong> – E<\/strong> (Element): Platinum is a pure element with the symbol Pt and atomic number 78.<\/li>\n\n\n\n
  13. Justice<\/strong> – X<\/strong>: Justice is a concept, not a physical substance, so it doesn’t fall under element, compound, or mixture.<\/li>\n\n\n\n
  14. Brass<\/strong> – M<\/strong> (Mixture): Brass is an alloy made primarily of copper and zinc, which are mixed physically.<\/li>\n\n\n\n
  15. Water<\/strong> – C<\/strong> (Compound): Water (H\u2082O) is a compound made of hydrogen and oxygen atoms chemically bonded.<\/li>\n\n\n\n
  16. Gold<\/strong> – E<\/strong> (Element): Gold is a pure element with the symbol Au and atomic number 79.<\/li>\n\n\n\n
  17. Chocolates<\/strong> – M<\/strong> (Mixture): Chocolates are a mixture of cocoa, sugar, milk, and other ingredients that are not chemically bonded in a fixed ratio.<\/li>\n\n\n\n
  18. Diesel Oil<\/strong> – M<\/strong> (Mixture): Diesel oil is a mixture of hydrocarbons and other substances used as fuel.<\/li>\n\n\n\n
  19. Shampoo<\/strong> – M<\/strong> (Mixture): Shampoo is a mixture of water, detergents, fragrances, and other chemicals used for cleaning.<\/li>\n\n\n\n
  20. Isopropyl<\/strong> – C<\/strong> (Compound): Isopropyl alcohol (C\u2083H\u2088O) is a compound made up of carbon, hydrogen, and oxygen atoms chemically bonded.<\/li>\n<\/ol>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n
      \n
    • Elements (E)<\/strong> are pure substances made of only one type of atom, like gold<\/strong>, mercury<\/strong>, and diamond<\/strong>.<\/li>\n\n\n\n
    • Compounds (C)<\/strong> consist of two or more different elements chemically bonded in fixed proportions, like sugar<\/strong> (sucrose), water<\/strong>, and salt<\/strong>.<\/li>\n\n\n\n
    • Mixtures (M)<\/strong> contain two or more substances physically combined, where the components retain their individual properties. Air<\/strong>, popcorn<\/strong>, wood<\/strong>, bronze<\/strong>, and ink<\/strong> are all mixtures.<\/li>\n\n\n\n
    • Justice<\/strong> is an abstract idea and doesn\u2019t fit into any of these categories. Therefore, it\u2019s classified as X<\/strong>.<\/li>\n<\/ul>\n\n\n\n
