What will most likely happen when these molecules get closer? The molecules will repel each other because of a dipole-dipole int
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.

How many molecules are in 25g of Na2SO4?
bearhunter [10]
Hey there!

Molar mass Na2SO4 = 142.04 g/mol

Number of moles:

n = m / mm

n = 25 / 142.04

n = 0.176 moles of Na2SO4

Therefore, use the Avogadro constant

1 mole Na2SO4 ------------------- 6.02x10²³ molecules
0.176 moles Na2SO4 ------------   molecules ??


0.176  x  ( 6.02x10²³ ) / 1 

=> 1.059x10²³ molecules of Na2SO4

hope this helps!
