I would say physical, because a physical change is affecting the form of a chemical substance, but not it's chemical makeup.
There are 5 significant figures in the following number. All of the numbers essentially are significant.
Answer:
Metallic bonding
Explanation:
Metals have low ionization energies. Therefore, their valence electrons are easily delocalized (attracted to the neighbouring metal atoms). These delocalized electrons are then not associated with a specific metal atom. Since the electrons are “free”, the metal atoms have become cations, and the electrons are free to move throughout the whole crystalline structure.
We say that a metal consists of an array of cations immersed in a sea of electrons
.
The electrons act as a “glue” holding the cations together.
Metallic bonds are the attractive forces between the metal cations and the sea of electrons.
In an NaK alloy, for example, the Na and K atoms contribute their valence electrons to the "sea". The atoms aren’t bonded to each other, but they are held in place by the metallic bonding.
The substance that will form a solution when mixed with solid sodium chloride would be CH₂OH
<h3>Solubility of NaCl</h3>
A solution is only formed when a solute dissolves in a solvent.
In this case,
and CH₂OH are the only liquid solvents. However, NaCl is insoluble in
while it is soluble in CH₂OH due to its polarity.
Thus, NaCl can form a solution only with CH₂OH.
