1, what is the difference between a homogeneous mixture and a heterogeneous mixture
Answer (1)
Homogeneous Mixture: A homogeneous mixture is a mixture where the components are uniformly distributed throughout, making it appear as a single substance. You cannot distinguish the individual components with the naked eye, even under magnification. These mixtures often consist of a single phase (e.g., all liquid, all gas, or all solid). A common example is saltwater, where the salt is dissolved evenly in the water and you can't see the individual salt particles. Solutions are a type of homogeneous mixture.Heterogeneous Mixture: A heterogeneous mixture is a mixture where the components are not uniformly distributed and can be distinguished visually (or with simple magnification). It consists of two or more distinct phases, meaning you can often see different parts or layers. Examples include a salad (you can see the lettuce, tomatoes, cucumbers), sand and water (the sand settles at the bottom), or oil and vinegar in salad dressing (they separate into layers).
