What is the difference between a heterogenous and homogeneous mixture? And some examples for each heterogenous and homogeneous.
Since this is not my area of expertise, I searched Google under the key words "difference heterogenous homogeneous mixture" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
A heterogeneous mixture is one that consists of different substances or components that can be visibly distinguished or separated by physical means. On the other hand, a homogeneous mixture is one that appears uniform throughout and has the same composition in every part of the mixture.
To understand the difference between these two types of mixtures, let's look at some examples:
Heterogeneous mixtures:
1. Salad: A salad is a heterogeneous mixture because it consists of various ingredients such as lettuce, tomatoes, cucumbers, and onions, which can be easily seen and separated.
2. Chocolate chip cookie: In a chocolate chip cookie, the chocolate chips are distributed unevenly throughout the cookie, creating a heterogeneous mixture.
Homogeneous mixtures:
1. Saltwater: When you dissolve salt in water, it forms a homogeneous mixture. The salt particles become evenly distributed and cannot be easily separated.
2. Air: Air is a homogeneous mixture of gases such as nitrogen, oxygen, carbon dioxide, and others. These gases are thoroughly mixed and cannot be visually separated.
To determine whether a mixture is heterogeneous or homogeneous, you can observe the mixture and check if you can visually distinguish or separate its components. If you can see different parts or phases, it is heterogeneous. If the mixture appears uniform throughout, it is homogeneous.
