What else can I help you with?
Does mixtures have a composition?
Mixtures don't necessarily have fixed composition
What are the characteristics of homogeneous mixtures?
Has the same composition and has one phase. for some people The correct answers are: Consistent composition, and Smooth
How is homogenoues different from heterogenous?
Homogeneous mixtures have uniform composition throughout, with the same properties in all parts. Heterogeneous mixtures have non-uniform composition, with distinct phases or regions that can be visually identified.
What is a uniform mixtures?
A uniform mixture is : A sample of matter that has the same composition and properties throughout.
What are the two classification of mixtures?
Homogeneous mixtures and Heterogeneous mixtures. Homogeneous mixtures are those mixtures whose composition is same throughout i.e., the different components cannot be observed. The mix completely. for example, in true solutions like salt or sugar solution you cannot see the sugar or salt after mixing. They are completely mixed. Also, one spoon of that solution will have the same composition as 2 spoons of the same solution. Heterogeneous mixtures on the other hand, do not have the same composition. They do not mix thoroughly and hence the different components can be observed. For example, when you mix salt and sugar or salt and sand, you can make out which is salt and which is the other substance.

Why air is not a heterogeneous mixture?
Well, air contains 78.09% of Nitrogen, 20.95% of Oxygen, 0.03% of Carbon Dioxide and the rest of the gases like Argon, Helium, etc for about 1%. This composition of air is the same no matter where you go. If you're in Australia, the air will have this composition. If you're in South Africa, the air will have the same composition. The basic idea here is that the composition of air doesn't change which means air has a uniform composition. Homogeneous mixtures are those mixtures whose composition is same throughout the mixture and a heterogeneous mixtures are those mixtures whose composition is not same. Also, homogeneous mixtures are mixtures in which its components mix up thoroughly, i.e., the components cannot be observed whereas in a heterogeneous mixture, the individual components can be observed. In air, the Nitrogen or Oxygen cannot be observed separately. It is uniform and homogeneous. Thus, air is not a heterogeneous mixture.
What is it called when a mixture can vary in composition?
Based on the distribution of their components, mixtures can be classified as heterogeneous mixtures or as homogenous mixtures.
Does the composition of a substance always stay the same?
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.
Are elements a pure mixture?
Chemical elements are not mixtures (I do not think to the isotopic composition).
Why dont compounds differ from mixtures?
Compounds differ from mixtures because compounds have a fixed chemical composition with elements chemically bonded in a specific ratio, while mixtures can vary in composition with no fixed ratio. Compounds have specific properties different from their constituent elements, while mixtures retain the properties of their components.
How are homogeneous and heterogeneous similar?
Homogeneous and heterogeneous are both terms used to describe mixtures. Homogeneous mixtures have uniform composition throughout, whereas heterogeneous mixtures have uneven composition with visible boundaries between the components.
