<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>
Not A because
2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne
Is B because
DescriptionPentenes are alkenes with chemical formula C ₅H ₁₀. Each contains one double bond within its molecular structure.
Answer: The concentration of hydrochloric acid in the final solution is 0.72 M
Explanation:
According to the dilution law,
where,
= molarity of stock solution = 3.95 M
= volume of stock solution = 268 ml
= molarity of diluted solution = ?
= volume of diluted solution = 803 ml
Next, you take 100.00 ml of that solution and dilute it to 184 ml in a volumetric flask.
According to the dilution law,
where,
= molarity of stock solution = 1.32 M
= volume of stock solution = 100 ml
= molarity of diluted solution = ?
= volume of diluted solution = 184 ml
Thus concentration of hydrochloric acid in the final solution is 0.72 M
Answer:
Express these numbers in atomic mass units ("u"). Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. ( I asked my teacher about this too)
Explanation:
It’s d
I Did this myself and was right
