The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The false statement is:<\/p>\n\n\n\n

A) Different mixtures of the same two substances must have the same composition.<\/strong><\/p>\n\n\n\n

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

Let’s break down each option to understand why this is the false statement:<\/p>\n\n\n\n

A) Different mixtures of the same two substances must have the same composition.<\/strong><\/p>\n\n\n\n

    \n
  • This statement is false<\/strong> because mixtures do not have a fixed composition. In mixtures, the proportions of the components can vary. For example, if you mix salt and water, you can have a solution with varying concentrations of salt and water. This flexibility in composition is one of the defining characteristics of mixtures. In contrast, compounds have a fixed, specific ratio of elements.<\/li>\n<\/ul>\n\n\n\n

    B) A mixture of sea sand and table salt is an example of a heterogeneous mixture.<\/strong><\/p>\n\n\n\n

      \n
    • This statement is true<\/strong> because a heterogeneous mixture is one in which the individual components remain distinct and can be physically separated. Sea sand and table salt form a heterogeneous mixture because the sand and salt are visibly distinguishable, and you can separate them through physical means (such as filtering or dissolving the salt in water).<\/li>\n<\/ul>\n\n\n\n

      C) An example of a homogeneous mixture is one prepared by mixing drinking alcohol and water.<\/strong><\/p>\n\n\n\n

        \n
      • This statement is true<\/strong> because a homogeneous mixture is one where the composition is uniform throughout. When alcohol and water are mixed, they form a solution that has a consistent composition throughout. No distinct layers or components are visible, making it a homogeneous mixture.<\/li>\n<\/ul>\n\n\n\n

        D) A compound is a substance that can be decomposed into two or more simpler substances by chemical means.<\/strong><\/p>\n\n\n\n

          \n
        • This statement is true<\/strong> because a compound is a pure substance formed from two or more elements chemically bonded together. The elements in a compound cannot be separated by physical means but can be decomposed into simpler substances through chemical reactions (e.g., electrolysis of water into hydrogen and oxygen).<\/li>\n<\/ul>\n\n\n\n

          Thus, statement A<\/strong> is false because it incorrectly suggests that mixtures have a fixed composition, which is not true. Mixtures can vary in the ratio of components, while compounds have a fixed composition.<\/p>\n","protected":false},"excerpt":{"rendered":"
