The opposite of a heterogeneous mixture is a <strong>homogeneous mixture<\/strong>, where the substances are evenly mixed, and you cannot distinguish individual components.<\/p>\n\n\n\n<p>Let\u2019s break down each option:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>A) Sodium<\/strong>: Sodium is a <strong>pure substance<\/strong> (an element), not a mixture. It consists of only one type of atom (sodium atoms) and does not vary in composition. Hence, sodium is not a mixture, let alone a heterogeneous mixture.<\/li>\n\n\n\n<li><strong>B) Baking soda<\/strong>: Baking soda (sodium bicarbonate) is a <strong>compound<\/strong>, not a mixture. A compound is a substance made up of two or more elements that are chemically bonded in a fixed ratio. Since baking soda is a pure chemical substance with a uniform composition, it is not a heterogeneous mixture.<\/li>\n\n\n\n<li><strong>C) Dextrose (a sugar) dissolved in water<\/strong>: When dextrose (sugar) dissolves in water, it forms a <strong>homogeneous solution<\/strong>, meaning that the sugar molecules are evenly distributed in the water, and you cannot distinguish the sugar from the water with the naked eye. A homogeneous solution is a mixture where the components are uniformly mixed at the molecular level, so this is not a heterogeneous mixture.<\/li>\n\n\n\n<li><strong>D) Salt and pepper in a glass<\/strong>: This is a <strong>heterogeneous mixture<\/strong> because the salt and pepper particles are visibly distinct and not uniformly distributed. If you look at the mixture, you can clearly see the individual salt grains and pepper grains, and they do not combine chemically. You can also separate them physically, which is a key characteristic of a heterogeneous mixture.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>Thus, <strong>salt and pepper in a glass<\/strong> is the correct answer as it is an example of a heterogeneous mixture, where the components are not evenly distributed and can be visually distinguished.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following substances is a heterogeneous mixture?
