Mixtures that cannot be separated using sifting typically consist of components with similar particle sizes or those that are finely ground, such as flour and powdered sugar. Additionally, homogeneous mixtures, like saltwater or vinegar solutions, cannot be separated by sifting because their components are uniformly distributed at a molecular level. Sifting is most effective for mixtures with distinctly different particle sizes, such as sand and gravel.

What are the characteristics of a subtances and mixtures?
The components of a mixture are not chemically combined and do not have a definite composition. A pure substance is either an element or a compound (in which case it is composed of elements that are chemically combined) and has a definite composition.
What two groups are mixtures divided into?
Mixtures are divided into two groups: homogeneous mixtures, where the components are evenly distributed and indistinguishable, and heterogeneous mixtures, where the components are not evenly distributed and can be seen as separate phases.
What are hetogeneous mixtures?
Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixtureA heterogenous mixture is not uniform in composition and properties throughout.
How can you make energy using waterfalls?
it cant make energy it is kinetic if it flows
What substance cant be separated by filtration?
A solution, such as saltwater, cannot be separated by filtration because the solute (salt) is dissolved at the molecular level in the solvent (water). Filtration works by trapping larger particles while allowing smaller particles or dissolved substances to pass through, so dissolved substances remain in the solution. In contrast, substances like sand or gravel can be separated by filtration because they are solid particles that do not dissolve in the liquid.
Mixtures can what but compounds cant?
Mixtures can be separated by physical methods.
What are the characteristics of a subtances and mixtures?
The components of a mixture are not chemically combined and do not have a definite composition. A pure substance is either an element or a compound (in which case it is composed of elements that are chemically combined) and has a definite composition.
How can blood be separated from the plasma?
IT CANT
Why cant liquids dissolve in water?
Many liquids form mixtures with water !
How do compound and mixtures differ?
Elements are one type of element in a group where all the elements are the same or a lonely single atoms. Compounds are two or more different types of elements and mixtures are a lot of elements made so that unless you use a good separating technique you would not be able to separate them. an example is air you cant really separate that unless you use serious power hope this helps
What two groups are mixtures divided into?
Mixtures are divided into two groups: homogeneous mixtures, where the components are evenly distributed and indistinguishable, and heterogeneous mixtures, where the components are not evenly distributed and can be seen as separate phases.
What can compounds do that mixtures cant?
A compound is a simple substance, a mixture is formed from two or more compounds.
Why cant mixtures be represented by formulas?
Mixtures are composed of two or more different substances physically combined, so they do not have a fixed chemical composition like compounds. As a result, mixtures cannot be represented by chemical formulas which typically describe the specific ratio of elements in a compound.
How can you remove oils from water?
you cant really remove them because they are already separated
Is a colloid separated by filteration?
yes most likely because you cant separat a solution
What is the difference between heterogeneos and homegenous mixtures?
Heterogeneous mixtures have visibly different components that can be distinguished by the naked eye, such as a salad. Homogeneous mixtures have uniform composition throughout, like salt dissolved in water.
How do solutions compare and contrast with heterogeneous mixtures?
a mixture is a things or more mix together and a solution is 2 or more things that mix together that you cant see that well.
