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.

Entropy is the tax we pay for borrowing nature's power.discuss​
Alexxandr [17]

Answer:

Explanation:

Entropy is the thermal energy that is unavailable for humans to do useful work.human system normally progress from disorder to order. This entropy interferes with humans day to day activities. Once this energy is consumed it is converted from one form to another and it is the tax paid for those energies. It is the continuous dissipation of energy. For example if 1000J of energy is consumed, and nature take part of it, 900J is available for work.

a student is asked to prepare 75.0 ml of a 130M solution of HF using a 2.000M standard solution. Calculate the volume in mL of 2
Blizzard [7]

Answer:

Volume required from standard solution = 4675 mL

Explanation:

Given data:

Final volume = 75.0 mL

Final molarity = 130 M

Molarity of standard solution = 2.000 M

Volume required from standard solution = ?

Solution:

We use the formula,

C₁V₁ = C₂V₂

here,

C₁ = Molarity of standard solution

V₁ = Volume required from standard solution

C₂ = Final molarity

V₂ = Final volume

Now we will put the values in formula,

C₁V₁ = C₂V₂

2.000 M × V₁ = 130 M × 75.0 mL

V₁  = 9750 M. mL / 2.000 M

V₁  = 4675 mL
