In the Lewis structure, the Ca atom donates its two valence electrons to two F atoms.

The bonding in calcium fluoride (CaF₂) involves the transfer of electrons from calcium (Ca) to fluorine (F), resulting in the formation of ionic bonds.

Each F atom gains one electron to achieve a stable electron configuration of eight electrons in its outermost energy level. The electrostatic attraction between the positively charged Ca ion (Ca²⁺) and the negatively charged F ions (F⁻) holds the compound together.

It's important to note that the diagram represents a simplified 2-dimensional representation of the compound's structure. In reality, the compound adopts a three-dimensional crystal lattice structure, with each Ca ion surrounded by eight F ions and each F ion surrounded by four Ca ions.

Explanation:

Hi, there!!!!

Let me simply clear you..

Yes,The tendency to gain electrons (in nonmetal) decreases when we go down group 17.

The reason for above answer is when we go downwards in periodic table then the atomic size increases with the addition of number of shells and force of attraction between the nucleus and valance shell decreases. The force of attraction between the nucleus and valance shell becomes weaker due to which the force of attracting the electrons gets decreased.

So, we can say that the tendency to gain electrons decreases as we go down in periodic table.

Due to common purpose water and development are substitute of one another.

Water and development are substitute of one another because both contribute in the growth of economy of a country and increases life standard of its people. The presence of water causes growth and betterment of the economy that leads to development of the nation so we can say that due to same effect, both are used as a substitute i.e. in place of one another in the process of growth and betterment.

Answer:

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ is 4.11 × 10⁻³ grams

Explanation:

The number of particles in one mole of a substance id=s given by the Avogadro's number which is approximately 6.023 × 10²³ particles

Therefore, we have;

One mole of Cl₂ gas, which is a compound, contains 6.023 × 10²³ individual molecules of Cl₂

3.491 × 10¹⁹ molecules of Cl₂ is equivalent to (3.491 × 10¹⁹)/(6.023 × 10²³) = 5.796 × 10⁻⁵ moles of Cl₂

The mass of one mole of Cl₂ = 70.906 g/mol

The mass of 5.796 × 10⁻⁵ moles of Cl₂ = 70.906 × 5.796 × 10^(-5) = 4.11 × 10⁻³ grams

Therefore;

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ = 4.11 × 10⁻³ grams.

Answer:

Why is the unit of force called a derived unit? That's because the Newton is defined in terms of other units which are more fundamental. One Newton is the force required to accelerate a mass of one kilogramme at the rate of one metre per second squared.

Answer:

32.4°C

Explanation:

Consider the following expression:

P•V/T =P'•V'/T'

Where P and P' are respectively the initial and the final pressure, V and V's are respectively initial and final volume, and T and T' are respectively initial and final temperature.

We know that the pressure cannot change, so it means that P = P'

We also know that the volume must be increased in 20%, and if we multiply the volume by 1.2 is like increase it in 20%, so we can write that V' = 1.2•V, and changing a little more we can write that V'/V = 1.2

So let's do some maths:

P•V/T = P'•V'/T'

T'•P•V/T = P'•V'

T'•P•V = P'•V'•T

T'=P'•V'•T/P•V

We know that P'=P so the division is equal to 1:

T'= 1•V'•T/V

We also know that V'/V = 1.2, so:

T' = 1.2•T

And we know the value of T, it's 27, so now we just have to solve it:

T' = 1.2•27

T' = 32.4°C

Answer:

Oxygen does not burn. It is not flammable, but it is an oxidizer.

Explanation

I think you are misunderstanding what is meant by "fire burns up air". Fire does use oxygen when it burns. But it also produces carbon dioxide. An oxygen molecule has two oxygen atoms in it. Fires use this to produce carbon dioxide by adding a single carbon atom from the fire’s fuel (wood, for instance).

Answer:

Distillation:

Distillation is the process in which two or more liquids are separated on the basis of their boiling points.

Process:

Liquid mixture is heated. The liquid which is of low boiling point evaporates first and is condensed separately. This is followed by the liquid having more boiling point than the previous one and so on.

Reason:

A mixture of liquids having almost same boiling points cannot be separated. This is because both the liquids will evaporate at almost the same time when heated and thus, we will obtain the same liquid mixture again. No separation will occur.

Answer:Percent error= 90.9%

Explanation:

Percent error or percentage error is defined as the  percentage of the  difference between a measured value usually from an experiment and an exact  value in comparison to the exact number.

its formula is thus

Percent error = experimental value - exact or actual value /exact value x 100

=(18.9 - 9.9 /9.9 ) x 100= 9/9.9) x 100

0.909 x 100 = 90.90 = 90.9%

Answer:

The correct answer is 5.08 atm

Explanation:

This question tests our knowledge of the Dalton's law of partial pressures which is stated in the question; that the pressure of a mixture of non-reacting gases in a single container is the sum of all the pressures of the individual gases.

It can hence be represented mathematically as Ptotal = Pa + Pb + ...

Ptotal = pressure of methane + pressure of ethane

Ptotal = 3.4 atm + 1.68 atm

Ptotal = 5.08 atm

Answer:

Neutral

Explanation:

We can consider this salt as a neutral one. It can be prepared by a neutralization reaction between the base and the acid.

CsOH  + HBr →  H₂O  + CsBr

As the two reactants are strong, the HBr as a strong acid, and the CsOH as a strong base, the ions are considered as: the weak conjugate acid and the weak conjugate base.

Br⁻  +  H₂O ← HBr + OH⁻

Cs⁺  +  H₂O ←  CsOH  +  H⁺

They can not react to water, that's why the salt is neutral (similar as the NaCl)

pH = 7
