<span>the polarity of the solute or the solvent.
for example:
oil will not mix with water because oil molecules are nonpolar however water moleculses are polar. so, they will not mix with each other.
when we put sodium chloride in water, sodium chloride will be easily dissoved. because both sodium chloride and water are polar.
in other case, if we put sodium chloride and hexane together. sodium chloride will not dissove in hexane, because hexane is a nonpolar solvent.
finally, if we try to mix hexane and bromine together, they will mix uniformly. because both hexane and bromine are nonpolar. (note: most diatomic molecules are nonpolar, such as hydrogen gas, oxygen gas, chlorine gas, etc. )
so just remember, nonpolar and nonpolar will dissovle each other. and polar and polar will dissolve each other.</span>
It's A.
Chemical properties cannot be determined by viewing or touching substance, and physical properties can be measured without changing the composition of matter:)
Consequently, the ion with the greatest nuclear charge (Al 3 +) is the smallest, and the ion with the smallest nuclear charge (N 3−) is the largest. The neon atom in this isoelectronic series is not listed in Table 2.8.3, because neon forms no covalent or ionic compounds and hence its radius is difficult to measure.
Answer:
C.) Csp² - Nsp³
Explanation:
Because the carbon has only 3 unique bonds, the conformation of the carbon should be Csp² (s + p + p). While the nitrogen also has only 3 bonds, making up 3 orbitals, it also has a lone pair of electrons. These electrons also take up one orbital. Therefore, the conformation of nitrogen is Nsp³ (s + p + p + p).
The term mole refers to 6.02x10²³ atoms or molecules of any substance. so regardless of the substance one mole will always be equivalent to 6.02x10²³
Hope that helps
