Hydrogen chloride<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Explanation<\/strong><\/h3>\n\n\n\n<p>A <strong>mixture<\/strong> is a combination of two or more substances that are <strong>not chemically bonded<\/strong> and can be <strong>physically separated<\/strong>. Mixtures can be homogeneous (uniform composition, like salt water) or heterogeneous (non-uniform, like salad).<\/p>\n\n\n\n<p>Let\u2019s examine each option:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. Antibiotic<\/strong>: Most antibiotics sold for treatment (like syrups or capsules) are <strong>formulated mixtures<\/strong> containing active pharmaceutical ingredients and excipients (binders, preservatives, coloring agents, etc.). These are mixtures because they involve more than one substance combined physically.<\/li>\n\n\n\n<li><strong>b. Evaporated milk<\/strong>: This is <strong>milk with about 60% of the water removed<\/strong>, but it still contains proteins, fats, lactose, vitamins, and minerals. All these components are <strong>not chemically bonded<\/strong>, so evaporated milk is a <strong>homogeneous mixture<\/strong>.<\/li>\n\n\n\n<li><strong>c. Brewed coffee<\/strong>: Brewed coffee is a mixture of water and various soluble compounds from ground coffee beans, like caffeine, acids, and oils. These are <strong>not chemically combined<\/strong>, making coffee a <strong>homogeneous mixture<\/strong>.<\/li>\n\n\n\n<li><strong>d. Hydrogen chloride (HCl)<\/strong>: <strong>This is not a mixture<\/strong>. Hydrogen chloride is a <strong>pure chemical compound<\/strong>, consisting of one hydrogen atom and one chlorine atom <strong>chemically bonded<\/strong> in a 1:1 ratio. Whether in gaseous form or dissolved in water (forming hydrochloric acid), HCl remains a <strong>compound<\/strong>, not a mixture. Its elements are combined through <strong>chemical bonding<\/strong>, and it cannot be separated by physical means like filtration or evaporation.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the only <strong>non-mixture<\/strong> among the options is <strong>hydrogen chloride<\/strong>, because it has a <strong>definite chemical composition<\/strong> and its components are <strong>chemically combined<\/strong>, distinguishing it from the physical combinations found in mixtures.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Final Answer: d.
