Answer:

Explanation:
Hello,
In this case, the change in the entropy, by knowing the change in the enthalpy and the temperature for a vaporization process is given by:

Thus, we start by computing the change in the enthalpy for the 3.3g of dichloromethane as shown below:

Finally, the change in the entropy, considering the temperature in kelvins:

Best regards.

In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.
Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.
However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should find a way to make nylon without using natural resources.

To answer this, we look at the polarities of these molecules given. A molecule is said to be polar when there is an unequal shraing of electrons the opposite is called nonpolar.
CH4 = nonpolar
CH3OH = polar
CH3 CH3 = nonpolar
CH3 CH2 CH2 OH = polar
<span>CH3 CH2 CH2 CH2 CH2 CH3 = nonpolar</span>
Explanation:
The given data is:
The mass% of a solution is 7.
Mass of solution =450g
The mass of salt required can be calculated as shown below:

Substitute the given values in this formula to get the mass of solute that is salt:

Mass of salt =31.5g
Mass of solvent that is water = 450g-31.5g=418.5g
