In mixtures, the substances retain their individual properties.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. Antibiotic<\/strong> \u2013 Most antibiotics, especially in pill or liquid form, are actually mixtures containing the active compound along with fillers, preservatives, or solvents.<\/li>\n\n\n\n<li><strong>b. Evaporated milk<\/strong> \u2013 This is a mixture, primarily composed of water, fats, sugars, and proteins.<\/li>\n\n\n\n<li><strong>c. Brewed coffee<\/strong> \u2013 Coffee is a mixture of water and hundreds of soluble compounds extracted from coffee grounds.<\/li>\n\n\n\n<li><strong>d. Hydrogen chloride (HCl)<\/strong> \u2013 This is a <strong>pure substance<\/strong>, not a mixture. It is a <strong>compound<\/strong>, formed by chemically combining hydrogen and chlorine in a fixed 1:1 ratio. Unlike a mixture, the components of a compound cannot be separated by physical means.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, <strong>hydrogen chloride<\/strong> is not a mixture; it is a compound.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Question 2: Which is a homogeneous mixture?<\/strong><\/h4>\n\n\n\n<p>A <strong>homogeneous mixture<\/strong> is a mixture with a uniform composition throughout. Its components are not visibly distinguishable.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. Air<\/strong> \u2013 Air is a <strong>homogeneous mixture<\/strong> of gases like nitrogen, oxygen, carbon dioxide, etc. The gases are evenly mixed, and you can&#8217;t distinguish one gas from another with the naked eye.<\/li>\n\n\n\n<li><strong>b. Blood<\/strong> \u2013 Blood is a <strong>heterogeneous mixture<\/strong>. It contains visible components under a microscope like red and white blood cells suspended in plasma.<\/li>\n\n\n\n<li><strong>c. Clouds<\/strong> \u2013 Clouds are made of tiny water droplets or ice crystals suspended in the air, making them <strong>heterogeneous<\/strong>.<\/li>\n\n\n\n<li><strong>d. Smog<\/strong> \u2013 Smog is a <strong>heterogeneous mixture<\/strong> of pollutants, gases, and particulates.<\/li>\n<\/ul>\n\n\n\n<p>Hence, <strong>air<\/strong> is the correct answer because it is <strong>uniform<\/strong> and <strong>homogeneous<\/strong> throughout.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is not a mixture? a. antibiotic b. evaporated milk c. brewed coffee d. hydrogen chloride 4.
