No chlorine will not react with potassium fluoride solution because chlorine reacts with water, forming HOCI and HCI. The only way for there to be a reaction when you add KF (Potassium Fluoride) to chlorine water is if there were any impurities in the water, even then it is doubtful that a color change would occur.

Answer : The chlorine water will not react with potassium fluoride solution because chlorine is less reactive halogen than the fluorine.

Explanation :

Displacement of halogen : If halogen is added to the solution of compound containing a less reactive halogen then it will react with compound and form a new product. This is also known as displacement reaction.

For example : Fluorine water react with sodium chloride solution to give sodium fluoride as chlorine water as a product.

The balanced chemical reaction will be:

$F_2(aq)+NaCl(aq)\rightarrow 2NaF(aq)+Cl_2(aq)$

In this reaction, a most reactive halogen (fluorine) displace a less reactive halogen (chlorine).

According to the question,

Chlorine water react does not react with potassium fluoride solution because chlorine is less reactive halogen than the fluorine. So, it will not displace fluorine halogen form the solution.

$Cl_2(aq)+KF(aq)\rightarrow \text{No reaction}$

To solve this problem it is necessary to apply the concepts related to Hooke's Law as well as Newton's second law.

By definition we know that Newton's second law is defined as

$F = ma$

m = mass

a = Acceleration

By Hooke's law force is described as

$F = k\Delta x$

Here,

k = Gravitational constant

x = Displacement

To develop this problem it is necessary to consider the two cases that give us concerning the elongation of the body.

The force to keep in balance must be preserved, so the force by the weight stipulated in Newton's second law and the force by Hooke's elongation are equal, so

$k\Delta x = mg$
