before looking at what the question says ,

let's have some general information related to the topic of the question !

__________________________

[tex]\implies \: [/tex] Electric field refers to the force generated by a nearby charge in the surroundings.

__________________________

[tex]\implies \: [/tex] Mathematically ,

Electric field = [tex]\frac{Kq}{r^{2}} \\[/tex]

where ,

K = coulomb's constant

q = magnitude of charge

r = distance between the opposite terminals

___________________________

[tex]\implies \: [/tex] Dipole moment , P = 2qd

where ,

q = magnitude of charges

d = distance between the charges

___________________________

[tex]\implies \: [/tex] positive charge tends to throw the field away from it while negative charge tends to pull the field towards it !

_____________________________________

seems like enough of information , so now let's look at the derivation !

refer the attachments in order to see the derivation !

Final answer -

[tex]\bold\pink{E = \frac{2kp}{(x {}^{2} - d {}^{2} ) {}^{2} } } \\ [/tex]

while , for a short dipole

[tex]\bold\pink{E = \frac{2pk}{x {}^{3} }} \\ [/tex]

Explanation:

Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :

*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue

* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.

CO2 and H2O react to form H2CO3 and two bonds are broken each in CO and H2O to form H2CO3.

Chemical bonding refers to the forces of attraction which hold atoms of the same or different elements together in order to form stable compounds or molecules .

Chemical bonding may be either ionic or covalent.

The greater the number of bonds in a compound, the more stable the compound.

During chemical reactions, bonds are broken and new binds are formed.

There are two bonds each in CO2 and H2O.

This, in the reaction between CO2 and H2O react to form H2CO3, , the number of bonds broken in H2O is two and in CO2 is two.

Explanation:

The role of conservation of linear momentum is important to your safety as a pedestrian or a motorist because you will avoid being hit by car.

The principle of conservation of linear momentum states that the sum of the initial momentum of an isolated system is equal to the sum of the final momentum.

The role of conservation of linear momentum is important to your safety as a pedestrian or a motorist because you will avoid being hit by car which is in motion, knowing that impulse you will receive will be equal to the change in the momentum of the car.

Answer: it has full valence shells

Explanation: Hope this is it

Answer:

Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).

The activating groups are; -NH2, -NR2 > -OH, -OR> -NHCOR> -CH3. while the deactivating groups are;  -NO2, -CF3> -COR, -CO2R, -SO3H > Halogens.

Owing to the  unusual stability of the benzene ring, it does not undergo  addition like other unsaturated species, rather benzene does undergo electrophillic substitution.

The substituent groups determine whether the molecule will be activated or deactivated towards electrophilic substitution, the following groups decativate benzene towards electrophilic substitution; -NO2, -CF3> -COR, -CO2R, -SO3H > Halogens. The following groups activate benzene ring towrads electrophilic substitution; -NH2, -NR2 > -OH, -OR> -NHCOR> -CH3.

1.8 x 10⁻³ is the molar solubility. Solubility is the amount of a substance that can be dissolved in a liquid to form a solution.

Solubility is the amount of a substance that can be dissolved in a liquid to form a solution; it is typically represented as grammes of solute every litre of liquid. One fluid's (liquid or gas) solubility in another can be entire (e.g., methanol and water are completely miscible) or partial (e.g., oil and water barely mix). Generally speaking, "like dissolves like" (for instance, the aromatic hydrocarbons dissolves in one another but not in water).

A material's solubility in two solvents is measured by the distribution coefficient, which is used in some separation techniques (such as absorption and extraction). In general, as temperature rises, so do the dissolution rates of solids in liquids, while they fall as temperature rises and rise with pressure for gases.

Answer: PO43

Explanation: The structure and formula are as follows: The chemical structure of phosphate is PO43-.

The molecular mass is 94.97 g/mol.

Answer:

B

Explanation:

We can use Planck's equation. Recall that:
[tex]\displaystyle E = h\nu[/tex]

Where h is Planck's constant and ν is the frequency.

We also have that:
[tex]\displaystyle \lambda \nu = c[/tex]

Where c is the speed of light and λ is the wavelength. Hence:

[tex]\displaystyle \nu = \frac{c}{\lambda}[/tex]

Therefore:
[tex]\displaystyle E= h\left(\frac{c}{\lambda}\right)[/tex]

Solving for λ yields:
[tex]\displaystyle \lambda = \frac{hc}{E}[/tex]

Hence substitute. Recall that h = 6.626 × 10⁻³⁴ Js and c = 2.998 × 10⁸ m/s:

[tex]\displaystyle \begin{aligned} \lambda & = \frac{(6.626\times 10^{-34}\text{ Js})(2.998\times 10^8\text{ m/s})}{4.56\times 10^{-19} \text{ J}} \left(\frac{1\times 10^9\text{ nm}}{1\text{ m}}\right) \\ \\ & = 436\text{ nm}\end{aligned}[/tex]

In conclusion, our answer is B.
