Okay, pls give brainliest because I answered the fastest and how are you?
Answer:
Explanation:
The physical methods of separating mixtures are used in sorting a mixture of substances.
It requires no chemical changes occurring between their components and parts in any significant way.
Examples are:
- Decantation
- Filtration
- Sublimation
- Magnetism
- Centrifugation
The methods simply relies on the physical properties of matter.

I think it's Molality because the moles of solute over the kilograms of solvent is equal to the molality...
Answer:
Metallic bonds
Explanation:
Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.
- The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
- The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.
This way the bond in pennies are metallic in nature.
