What is a homogeneous mixture? Which of the following are pure substances? Which of the following are homogeneous mixtures? Explain your answers. (a) Salt dissolved in water; (b) tea and ice; (c) chicken noodle soup; (d) mud; (e) gasoline; (f) carbon dioxide; (g) mint chocolate-chip ice cream.<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n A homogeneous mixture<\/strong> is a combination of two or more substances that are uniform in composition and appearance throughout<\/strong>. In these mixtures, you cannot see the individual components<\/strong>, and the composition is the same no matter where you sample it. Common examples include air, saltwater, and vinegar.<\/p>\n\n\n\n (a) Salt dissolved in water<\/strong> \u2013 Homogeneous mixture<\/strong> (b) Tea and ice<\/strong> \u2013 Heterogeneous mixture<\/strong> (c) Chicken noodle soup<\/strong> \u2013 Heterogeneous mixture<\/strong> (d) Mud<\/strong> \u2013 Heterogeneous mixture<\/strong> (e) Gasoline<\/strong> \u2013 Homogeneous mixture<\/strong> (f) Carbon dioxide<\/strong> \u2013 Pure substance<\/strong> (g) Mint chocolate-chip ice cream<\/strong> \u2013 Heterogeneous mixture<\/strong> Homogeneous mixtures:<\/strong> (a) Salt dissolved in water, (e) Gasoline What is a homogeneous mixture?

\n\n\n\nClassification of Each Substance:<\/strong><\/h3>\n\n\n\n
Explanation: When salt dissolves in water, it forms a uniform solution. You cannot see the salt crystals, and every part of the solution tastes the same. This is a textbook example of a homogeneous mixture.<\/p>\n\n\n\n
Explanation: Tea is homogeneous, but once you add ice (solid water) to it, there are distinct phases (liquid and solid). The composition varies (tea in the liquid part, ice in the solid part), making it heterogeneous.<\/p>\n\n\n\n
Explanation: You can see and separate the ingredients like chicken pieces, noodles, and broth. These components are not uniformly distributed, so it is not homogeneous.<\/p>\n\n\n\n
Explanation: Mud consists of water mixed with soil or clay. It\u2019s not uniform throughout, and particles settle over time. This makes it a heterogeneous mixture.<\/p>\n\n\n\n
Explanation: Gasoline is a carefully blended mixture of hydrocarbons. It appears uniform and consistent, so it qualifies as a homogeneous mixture.<\/p>\n\n\n\n
Explanation: CO\u2082 is a compound made of carbon and oxygen in a fixed ratio. It cannot be separated into components by physical means and is therefore a pure substance.<\/p>\n\n\n\n
Explanation: You can see and taste different parts like chocolate chips and ice cream. The composition is not uniform, so it\u2019s heterogeneous.<\/p>\n\n\n\n
