What else can I help you with?
Can materials in a simple mixture be separated or combined because they have different properties?
They can be separated
Which two physical properties allow a mixture to be separated by chromatography?
Size and shape. However, chemical properties are usually more important.
What property does the separation technique depend on?
The separation technique used depends on the differences in the physical or chemical properties of the substances being separated. Some common properties include size, solubility, boiling point, and density. By exploiting these differences, the technique can efficiently separate the substances.
What is ment by nanotechnology in detail?
Nanotechnology is the manipulation of materials on an atomic or molecular scale to create new structures with unique properties. It involves working with nanoparticles, which are particles that are between 1 and 100 nanometers in size. This field has applications in various industries, such as medicine, electronics, and energy.
How do molecular sieves work to separate molecules based on size and shape?
Molecular sieves work by trapping molecules that are too large to pass through their pores, while allowing smaller molecules to pass through. This separation is based on the size and shape of the molecules, with larger molecules being excluded from passing through the sieve.
How does nanotechnology help in making metamaterials?
Nanotechnology enables the precise manipulation of materials at the atomic and molecular levels, allowing for the design and fabrication of metamaterials with unique properties that are not found in nature. By controlling the size, shape, and arrangement of nanoparticles, nanotechnology can create structures that interact with light and sound in unconventional ways, leading to the development of metamaterials with tailored electromagnetic and acoustic properties.
What properties do you use to separate mixtures?
Some of the types of properties that can be used to separate mixtures are:FiltrationDistillationChromatographyMagnetismFloatationExtractionCrystallizationMechanical Separation
What is molecular exclusion chromatography?
Molecular exclusion chromatography is a type of size exclusion chromatography that separates molecules based on their size and shape. It works by passing a sample mixture through a porous stationary phase, where smaller molecules are able to enter the pores and take longer to elute, while larger molecules pass more easily through the column and elute faster. This technique is commonly used for separating proteins and nucleic acids.
What is meant by grade of a threaded fastener?
A grade denotes the mechanical properties of a screw - the materials used, size, direction of the thread and so on.
How is nanotechnology related to materials science?
Nanotechnology is about material, but in material science you work with any scale of them. if you decrease size of material's particle to nanometer, then you can find some useful properties. nanotechnology is working with materials in nanoscale.
What is the molecular size of phenol?
please i want to know the volume and area of phenol molecule
What kind of measurement can require accuracy to billionths?
Measurements in fields such as nanotechnology, semiconductor manufacturing, and atomic force microscopy require accuracy to billionths of a unit, often expressed in nanometers or angstroms. This level of precision is necessary to control the size, shape, and properties of materials at the atomic and molecular scales.
