Did you have any choices??
Answer:
C
Explanation:
Charles law states that volume of gas is directly proportional to temperature at constant pressure
V/T = k
where V - volume , T - temperature and k - constant
\frac{V1}{T1} = \frac{V2}{T2}
T1
V1
=
T2
V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
in the question it states that the temperature has been increased from 278 K to 231 K but it should actually be temperature is decreased from 278 K to 308 K
substituting the values in the equation
\frac{417cm^{3} }{278K} = \frac{V}{308 K}
278K
417cm
3
=
308K
V
V = 462 cm³
the answer should be C. 462 cm³
The question is as follows: What is the% m / m of a solution in which 22 g of solute are dissolved in 44 g of solvent?
Answer: The% m/m of a solution in which 22 g of solute are dissolved in 44 g of solvent is 50%.
Explanation:
Given: Mass of solute = 22 g
Mass of solvent = 44 g
The percentage m/m is calculated using the following formula.
Substitute the values into above formula as follows.
Thus, we can conclude that the% m/m of a solution in which 22 g of solute are dissolved in 44 g of solvent is 50%.
Answer: sorry for a late answer but it would be JJ Thompson
Explanation:
Dipole-Dipole interaction is the strongest type of intermolecular force between solute and solvent.
<h3>What is Intermolecular Force ?</h3>
Intermolecular force is also called secondary force is the force of attraction between molecules. It acts between ions and atoms.
<h3>What is Dipole-Dipole attraction ?</h3>
A dipole-dipole attraction is a weak attraction. It occurs when the two dipolar molecules interact with each other that means the attractive forces between the negative end of polar molecule and the positive end of another polar molecule.
CH₃Cl and CH₃OCH₃ both are polar in nature so dipole-dipole attraction is present.
Thus from the above conclusion we can say that Dipole-Dipole interaction is the strongest type of intermolecular force between solute and solvent.
