They can be separated by simple physical means like picking or sieving. In contrast, homogeneous mixtures (solutions) have components evenly mixed at the molecular level, making them appear as a single substance visually.<\/p>\n\n\n\n Thus, salt and pepper in a glass<\/strong> is the correct answer because it is a mixture with visibly distinct parts.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following substances is a heterogeneous mixture?

\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n
\n\n\n\nNow, let’s analyze each option:<\/h3>\n\n\n\n
Sodium (Na) is a chemical element and a pure substance, not a mixture. It consists of only sodium atoms and has uniform properties throughout.<\/p>\n\n\n\n
Baking soda is sodium bicarbonate (NaHCO\u2083), a pure chemical compound, so it\u2019s a substance, not a mixture.<\/p>\n\n\n\n
Dextrose (a sugar) dissolved in water forms a solution<\/strong>, which is a type of homogeneous mixture. The sugar molecules are evenly dispersed at the molecular level, so the mixture looks uniform throughout.<\/p>\n\n\n\n
Salt and pepper combined physically form a mixture where the two substances remain distinct. You can see the grains of salt and pepper separately, and they are not uniformly distributed. This makes it a heterogeneous mixture<\/strong>.<\/p>\n\n\n\n
