No. The composition of a homogeneous mixture, called a solution, can vary.
no
No, the composition of a homogeneous mixture is consistent throughout, meaning it has the same uniform properties in all parts of the mixture. This uniformity allows for the components to be evenly distributed at a molecular level.
I am not 100% sure, but i believe variable composition is when the composition of a mixture can vary, or contain different properties, elements/compounds... etc. An example of variable composition would be a heterogeneous mixture, which has no uniform way of being composed. Where as its opposite, a homogeneous mixture, has a set composition of the same properties, elements/compounds... etc. and can be recreated.
It is the former.
A pond could be a heterogeneous mixture because more than one substance would be visible. Example: you could see fish, plants, algie, bugs, chemicals, and other substances in the water. But, a pond could also be a homogeneous mixture because the water could be totally clear, or the water could be so dirty that you would only see a green or brown murky substance.
Sawdust is a heterogeneous mixture. It is made up of a variety of different size wood particles, which can vary in composition.
Yes, smog is considered a heterogeneous mixture because it consists of a variety of pollutants and particles suspended in the air. These components can vary in size, composition, and distribution throughout the smog, making it heterogeneous.
Oil is a heterogeneous mixture because it is composed of different substances that are not uniformly distributed throughout the mixture. Oil consists mainly of hydrocarbons, but it can also contain impurities and additives which can vary in composition and distribution.
Dirt is a heterogeneous mixture, as it consists of various components such as organic matter, minerals, water, and air, which are not uniformly distributed. The different particles in dirt can vary in size, composition, and origin, making it distinctly non-uniform. Unlike a homogeneous mixture, where the composition is consistent throughout, dirt exhibits visible variations.
Zucchini bread is not a homogeneous mixture; it is a heterogeneous mixture. While the ingredients are combined and baked, you can still distinguish between the different components, such as pieces of zucchini, flour, and other additives. The texture and appearance vary throughout the bread, making it inconsistent in composition. Homogeneous mixtures have a uniform composition throughout, which zucchini bread does not possess.
Air is considered homogeneous because it is a uniform mixture of gases, primarily nitrogen and oxygen, where the individual gas molecules are evenly distributed, making its composition consistent throughout. In contrast, dusty air is heterogeneous because it contains suspended particles, such as dust and pollutants, which can vary in size and concentration, leading to variations in composition and properties within the mixture. This difference in uniformity and distribution of components is what distinguishes homogeneous air from heterogeneous dusty air.
no
A juice is not a homogeneous mixture.
Yes, it is heterogenous mixture because the composition can vary throughout it.
No, the composition of a homogeneous mixture is consistent throughout, meaning it has the same uniform properties in all parts of the mixture. This uniformity allows for the components to be evenly distributed at a molecular level.
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.
