Why can gold be separated easily from surrounding material?
because of its denisty
How was the van der Waals force formed?
Van der Waals forces are weak intermolecular/inter atomic forces. Differentiated from covalent bonding, interionic attraction and hydrogen bondsThey are electrostatic forces due todipole dipole interactions (actually permanent multipoles)dipole -induced dipole interactionsinstantaneous dipole interactions (London dispersion forces- these are sometimes separated from Van der Waals)Sometimes intermolecular repulsion is included and these are due to Pauli exclusion principle.
What are the differences between colloidal precipitate and crystalline precipitate?
Crystalline precipitates have less surface area than the colloidal precipitates, therefore they are more pure. Additionally, crystalline precipitates, because they are larger, are more easily separated from the surrounding solution.
How is centrifugation better than filtration?
Filtration is a general term most often characterized by size separation (trap larger objects while letting smaller objects through, by chemical bonding/breaking, or electrostatic attraction. Centrifugation works with specific gravities or densities of materials to separate them. Which is better depends on what materials are being separated, and at what volumes.
How are diamonds extracted from their ore?
Diamonds erupted to the Earth's surface by volcanic pipes are generally xenocrysts -- foreign crystals, included within kimberlite diatremes. At the mine site, rocks are tumbled to separate the diamonds from the surrounding material under running water.Alluvial diamonds are found in riverbeds and at the mouths of rivers that flow over diamond-producing volcanic pipes, and are naturally already separated from the surrounding material.

What Mountains made of huge tilted blocks of rocks surrounding faults?
the faul-block mountains are made of huge tilted blocks of rock that are separated from surrounding rock by fault
How is cartilage separated from surrounding tissues?
Connective tissues separate the cartilage from the surrounding tissues. A break down of this tissue often leads to strain and pain in the joints.

Example of push are pull in science?
Attraction and Repulsion,the reason water can flow(Repulsion)but why it cant be separated(Attraction) not from an American(no offence) but every correct answer posted is automatically believed to be an a American. IDK Y tho but that is not always the case. BTW Americans are learned people but they aren't the only ones so lose that mindset because the planet is bigger than a nation.
When was chandigarh formed?
The foundation stone of the Chandigarh city was laid in 1952.
Where is the incision made in a Marshall-Marchetti-Krantz procedure?
An incision is made across the abdomen, and the bladder is exposed. The bladder is separated from surrounding tissues.
What is the purpose of capacitor in the circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)

What states surrounds Delaware?
Delaware shares a land border with Maryland and Pennsylvania. New Jersey can be said to be a state surrounding Delaware, but the land borders are separated by water.
What is a separated direct quotation?
A separated direct quotation is a quotation that is set apart from the main text with quotation marks or indentation. This helps to clearly identify the words being quoted as distinct from the surrounding text.
Is it separated or separated?
Separated.
