Why can mixtures be easily separated an compounds cannot?
Mixtures can be easily separated because the substances in mixtures retain their individual properties and can be physically separated based on differences in physical properties. Compounds, on the other hand, are chemically bonded, making it difficult to separate them without breaking the bonds and altering the chemical composition.
What mixtures can be something into their original substances?
Mixtures can often be separated back into their original substances through physical methods. For example, a heterogeneous mixture like salad can be disassembled by hand into its individual components. Similarly, a solution like saltwater can be separated by evaporation, leaving salt and water as distinct substances. However, chemical mixtures, like those formed through a chemical reaction, cannot be easily reverted to their original substances.
What are the examples of mixtures separated by hand picking?
Mixtures that can be separated by hand picking include a collection of dried beans mixed with small stones or debris, where the larger, unwanted stones can be easily removed by hand. Another example is a mix of different colored marbles or beads, where individuals can separate them based on color or size. Additionally, a bowl of mixed nuts can be sorted by hand to remove any shells or unwanted pieces.
What type of mixtures can be separated by hand?
Hand separation is effective for heterogeneous mixtures where the individual components are distinct and easily identifiable. Examples include mixtures of solids like sand and gravel, or larger objects like nuts and bolts. This method relies on physical properties, such as size, shape, or color, to facilitate the separation process. Generally, the components need to be large enough and sufficiently different to allow for manual sorting.
Can pure substances be mixtures?
No, pure substances cannot be mixtures. A pure substance is made up of only one type of atom or molecule, with uniform properties throughout the sample. Mixtures, on the other hand, are composed of two or more different substances physically combined, each retaining its individual properties.

Mixtures can be easily separated because the substances in mixtures retain their individual properties and can be physically separated based on differences in physical properties. Compounds, on the other hand, are chemically bonded, making it difficult to separate them without breaking the bonds and altering the chemical composition.
Can mixtures be separated much more easily than compounds?
Yes, mixtures can generally be separated more easily than compounds because the components of a mixture retain their physical properties and can be physically separated based on differences such as size, density, or solubility. Compounds, on the other hand, are chemically bonded, making them more difficult to separate.

What is the methods of separation of mixtures?
Mixtures can be separated by: Distillation, Chromatography, Evapouration, Filtration, Decantation, Crystalization, Magnatisim, Sorting By Hand, Sifting
What is the diiference between a heterogenous mixture and a pure substance?
A heterogeneous mixture can be separated into its components by physical means. On the other hand, compounds cannot be separated into their component elements expect by chemical means. Compounds are pure substances whereas mixtures are not.

Does mixing hand sanitizer with salt separate the alcohol?
No, mixing hand sanitizer with salt will not separate the alcohol from the other ingredients. Alcohol is a key component of hand sanitizer and cannot be easily separated through simple mixing methods.
Can pure substances be mixtures?
No, pure substances cannot be mixtures. A pure substance is made up of only one type of atom or molecule, with uniform properties throughout the sample. Mixtures, on the other hand, are composed of two or more different substances physically combined, each retaining its individual properties.
Do mixtures contain compounds?
No, mixtures do not contain compounds. Mixtures are made up of two or more substances that are physically combined and can be easily separated. Compounds, on the other hand, are made up of two or more elements that are chemically bonded together.
What are some mechanical mixtures found around the kitchen?
Some examples of mechanical mixtures found around the kitchen include a bowl of mixed nuts, a tossed salad, a trail mix blend, and a granola mix. These mixtures consist of physically combined components that can be easily separated by hand or tools.
Can a mixture be separated by some physical process?
yes it can
