Answer
The correct answer is:
b. dipole-dipole
Explanation:
The IMF molecules are linked by Van der Waals forces, which are permanent but dipole-dipole junctions.
If the interactions are molecules that are permanently polarized (for example, water molecules that attract other water molecules or other polar molecules), they are found as Keesom forces.
Answer:
P=atm
Explanation:
The problem give you the Van Der Waals equation:
First we are going to solve for P:
Then you should know all the units of each term of the equation, that is:
where atm=atmosphere, L=litters, K=kelvin
Now, you should replace the units in the equation for each value:
Then you should multiply and eliminate the same units which they are dividing each other (Please see the photo below), so you have:
Then operate the fraction subtraction:
P=
And finally you can find the answer:
P=atm
Now solving for b:
Replacing units:
Multiplying and dividing units,(please see the second photo below), we have:
Volume of a rectangle:
L x W x H
12.49 x 4 x 0.90 = 44.964
Answer : The two spontaneous chemical reactions are:
Explanation :
Gibbs free energy : It is defined as the amount of energy that is available to do useful work.
A reaction to be spontaneous when
A reaction to be non-spontaneous when
For the reaction to be spontaneous, the Gibbs free energy of the reaction is negative or we can say that the value of is less than zero.
From the given chemical reactions we conclude that there are two reactions that are spontaneous (favorable).
The two spontaneous chemical reactions are:
