Answers:<\/strong><\/h3>\n\n\n\n
    \n
  1. Orange juice<\/strong> \u2013 Mixture<\/strong>
    Why:<\/strong> Orange juice contains water, sugars, vitamins, pulp, and sometimes added flavorings or preservatives. These components are not chemically bonded and can vary in amount.<\/li>\n\n\n\n
  2. Halo-halo<\/strong> \u2013 Mixture<\/strong>
    Why:<\/strong> Halo-halo is a Filipino dessert made of crushed ice, milk, beans, jellies, fruits, and other sweet ingredients. These parts are physically combined and can be separated.<\/li>\n\n\n\n
  3. Carbon atom (C)<\/strong> \u2013 Pure Substance<\/strong>
    Why:<\/strong> A carbon atom is an element, meaning it consists of only one type of atom. It is a pure substance because it cannot be broken down by physical means.<\/li>\n\n\n\n
  4. Steel<\/strong> \u2013 Mixture<\/strong>
    Why:<\/strong> Steel is an alloy made mainly of iron and carbon, sometimes with other elements. These elements are combined physically and uniformly but not chemically bonded as in compounds.<\/li>\n\n\n\n
  5. Sugar (sucrose)<\/strong> \u2013 Pure Substance<\/strong>
    Why:<\/strong> Sugar (commonly sucrose) is a compound with a fixed chemical formula (C\u2081\u2082H\u2082\u2082O\u2081\u2081). It is a pure substance because it is made of the same molecules throughout.<\/li>\n<\/ol>\n\n\n\n

    Explanation:<\/strong><\/h3>\n\n\n\n

    In chemistry, matter is classified as either pure substances<\/strong> or mixtures<\/strong> based on its composition. Pure substances<\/strong> have a fixed composition and distinct chemical properties. They are either elements<\/strong> (like carbon) or compounds<\/strong> (like sugar). An element is made of only one type of atom, and a compound is made of two or more atoms chemically bonded in a specific ratio. These cannot be separated by physical methods.<\/p>\n\n\n\n

    On the other hand, mixtures<\/strong> consist of two or more substances physically combined. They retain their individual properties and can be separated by physical means like filtration or evaporation. Mixtures can be homogeneous<\/strong> (uniform throughout, like steel) or heterogeneous<\/strong> (not uniform, like halo-halo).<\/p>\n\n\n\n

    For example, orange juice<\/strong> contains pulp, water, and sugars \u2014 a typical heterogeneous mixture. Halo-halo<\/strong> is even more visibly a heterogeneous mixture, with different ingredients layered and mixed but not chemically bonded. Steel<\/strong>, though it appears uniform, is a homogeneous mixture (alloy) of iron and carbon. Carbon<\/strong> is a pure substance and an element with all atoms of the same kind. Sugar<\/strong> (sucrose), while made of different atoms, has a constant composition and is a compound, thus a pure substance.<\/p>\n\n\n\n

    Understanding these classifications helps in separating materials, predicting reactions, and identifying substances in everyday life and scientific study.<\/p>\n\n\n\n
