Lostsunrise [7]

The question is incomplete. The complete question is

In the molecule on the left, areas that have a partial negative charge are pink and areas that have a partial positive charge are blue. The molecule on the right is nonpolar.

What will most likely happen when these molecules get closer?

The molecules will repel each other because of a dipole-dipole interaction. The molecules will attract each other because of a dipole-dipole interaction. An induced dipole will be produced in the molecule on the right. An induced dipole will be produced in the molecule on the left.

Answer:

An induced dipole will be produced in the molecule on the right.

Explanation:

The molecule on the left already possesses a dipole. A dipole means the presence of a negative end and a positive end in a molecule.

Hence when the other molecule approaches, the polarized molecule induces a dipole on it. This second kind of dipole is known as 'induced dipole' hence the answer.

A sample of argon (Ar) gas has a volume of 7.31 L at a pressure of
Pie

Answer:

17.1 L

Explanation:

P1V1/T1  =  P2V2/T2        T is in K

P1V1/T1 * T2/P2 = V2

735 * 7.31 / (45+273.15)  * (55+ 273.15)/325 = V2

V2 = 17.1 L

How are the properties of thermosoftening and thermosetting polymers different? Use ​ideas about the structures of these two typ
stepan [7]

Thermosoftening plastics melt when they are heated.This means that they can be recycled , which involves melting them before making a new product. Thermosoftening plastics do not have covalent bonds between neighbouring polymer molecules, so the molecules can move over each other when heated and the plastic melts.
