please explain bonding of CCl 4

The reactivity of fluorine can be explained from molecular orbital theory with the calculation of the bond order.

The molecular orbital theory is assigned to explain the movement of the electrons in the bonding and anti-bonding orbitals.

The number of atom in the bonding and anti-bonding atomic orbits results in the elucidation of the bond order for the element.

The bond order and reactivity are inversely proportional to each other. The higher bond order depicts the presence of stronger bonds between the molecules and lower reactivity.

The bond order of fluorine atom is elucidated from the molecular orbital theory. The bond order of fluorine atom is 1, that explains the high reactivity of fluorine.

4. I think that they started with water that was the same tsmpurature because if they didnt start with the same temp of water then it would be harder to tell which one was better. and could hold the most heat.

5. yes i think it would matter, because if you have more water in one cup it might stay warmer than it would with the cups with less water, and if it was thicker it would hold mor heat because it is not so thin that the heat is just gonna come out it has to come through more for the heat to get out.

Answer:

1: 1, 2, 3

2: 2, 2, 3

3: 2, 1, 2, 1

Explanation:

A simple way to do this:

Take an extra page and write your formula at the top, then take your elements (for example in #1, N and H) and write them on the reactants and products sides. On the reactants side write down the numbers you have (N-2, H-2) and the same for the products side (N-1, H-3). Find your GCF's and then you got your answer. It takes a bit of time to figure out HOW to do it but its a good skill to have. I have attached #1 for you.

This seems to be a Hess' Law problem. Hess' Law states that "states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes." (Libretext)

Compare the step reaction to the final reaction to see the similarity and differences. We may have to flip an equation or multiply it by a constant to obtain the number of moles of the species in the final equation. Just remember, whatever we do to the equation, we have to do to the ΔH as well.

3C  +  4H₂  →  C₃H₈      ΔH= +104 kJ  [1]

      C + O₂ → CO₂        ΔH= -394 kJ  [2]

  2H₂ + O₂ → 2H₂O      ΔH= -572 kJ  [3]

C₃H₈  + 5O₂  → 3CO₂ + 4H₂O  ΔH = ?

_____________________________________________

Compare the Equation

Equation [1]

In [1] the C₃H₈is on the product side. But the final equation has the C₃H₈ on the reactant side. Thus we have to flip the equation. This flips the sign of ΔH.

                C₃H₈   →   3C  +  4H₂     ΔH= - 104 kJ  [1]

Equation [2]

The CO₂ in the final equation is on the product side but is 3 moles. Thus we have to multiply [2] by three. The ΔH is also multiplied by 3.

               3C + 3O₂ → 3CO₂        ΔH= 3 (-394 kJ)    [2]

Equation [3]

The H₂O in the final equation has a coefficient of 4. Thus we have to multiply [3] by 2.

              4H₂ + 2O₂ → 4H₂O      ΔH= 2(-572 kJ)  [3]

Combine the Equations

Combine the newly sorted versions of the equation and simplify to see if it matches the final equation. We also add the ΔH.

⇒  C₃H₈ +  3C + 3O₂ + 4H₂ + 2O₂   →   3C  +  4H₂  + 3CO₂ + 4H₂O

              ΔH= - 104 kJ + 3 (-394 kJ) + 2(-572 kJ)

⇒   C₃H₈ +  + 5 O₂   →  3CO₂ + 4H₂O

              ΔH= - 104 kJ + 3 (-394 kJ) + 2(-572 kJ) = −2430 kJ

Answer:

14 electrons max

Explanation:

The s sublevel just has one orbital, so can contain electrons max

Answer:

Explanation:

The elements in the long form of periodic table are classified into four blocks. They are s, p, d and f-block elements. The classification is based on the name of orbitals which receive the last electron. The elements in which the valence shell electron enters the s-orbital are called s-block elements.

Answer:

Sodium chloride solution contain free electron to conduct electricity. But in solution is not acid or basic media that is why not active in litmus paper

Explanation:

The sodium chloride solution a good conductor of electricity but does not have any effect on litmus paper because sodium chloride solution have free electron to conduct electricity. But in solution is not acid or basic media.

The sodium atoms and chlorine atoms separate when sodium chloride dissolves in water due to the influence of the water molecules. They are free to move as positively and negatively charged ions in the water. This charge separation enables the solution to conduct electricity.

Because cane sugar is a covalent compound bonded by electron sharing, a solution of cane sugar does not conduct electricity. There are no ions in the solution to conduct electrical charges across the solution.

Thus, sodium chloride solution have free electron to conduct electricity. But in solution is not acid or basic media.

2. 5 m/s

3. 180 km/hr 50 m/s

4. 30.56 m/s

5. 11.4 km/hr

Explanation:

#1 500 km/ 10 hours = 50 km/hr

#2 100 m/ 20 s = 5 m/s

#3 540 km/3 hrs = 180 km/hr

180 km/1 hr x (1000 m/ 1 km) x (1 hr/ 60 minutes) x (1 minute/ 60 seconds) = 50 m/s

Answer:

No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.

Explanation:

from the shape of methane which is tetrahedral it's evident there's no hydrogen bond only C-H bond.

The chemical formula of methane is [tex]CH_4[/tex] but: C. No, there is no bond between any of the hydrogen atoms because it would form [tex]H_2[/tex] instead of methane if hydrogen bonded with itself.

A chemical bond is defined as the forces of attraction existing between ions, crystals, atoms or molecules and they are mainly responsible for the formation of chemical compounds.

This ultimately implies that, a chemical bond refers to a force holding two or more atoms together and binding ions, crystals, or molecules together, in order to form a chemical compound.

Methane comprises of an atom of carbon and four (4) atoms of hydrogen.

Basically, hydrogen only shares a single (one) valence electron with carbon but not itself (hydrogen atoms) to form methane because of the [tex]sp^3[/tex] hybridization.

Hence, there is no bond existing between any of the four (4) hydrogen atoms because it would form [tex]H_2[/tex] instead of methane ([tex]CH_4[/tex]), if hydrogen bonded with itself.

Answer:

i think its replacement

Explanation:

By definition, the correct answer is the second option: the reaction is a replacement.

A simple substitution reaction or simple displacement reaction, called single-displacement reaction, is a reaction in which an element of a compound is substituted by another element involved in the reaction.

The starting materials are always pure elements and an aqueous compound. And a new pure aqueous compound and a different pure element are generated as products.

The general form of a simple substitution reaction is:

AB + C → A +BC

where C and A are pure elements; C replaces A within compound AB to form a new co, placed CB and elementary A.

A single-displacement reaction is characterized by a place of exchange of cations or anions with another to form a new product. A begins as an ion in the solution and appears elementally in the reaction products. In case of reagent C it starts in its elemental form and ends as an ion in an aqueous state forming compound BC.

In this case, it is a single replacement reaction where 1 atom of Zinc metal displaces 2 H⁺ ions from the hydrochloric acid to form hydrogen gas and zinc chloride, a salt.

Finally, the correct answer is the second option: the reaction is a replacement.

Answer:

270 sec . ( = 4 min . 30 sec . ) Explanation: Any radio wave is moving at the speed of light, regardless of the frequency, so the frequency should be superfluous information. The speed is light is close to 300 , 000 k m s I take the distance you are given, to be 8.2 ⋅ 10 7 k m (since 8.2 ⋅ 107 k m doesn't make good sense - it's less than 1000 km) i.e. 82 , 000 , 000 km.

Before we actually compute this, we can notice that this is a little more than half the distance of the earth from the sun (150 mill. km), a distance the light uses 500 sek. = 8 min 20 sec. to travel, so we should get about 4 1 2 min for the radio wave to reach Mars from the earth.

Actual calculation: 82 , 000 , 000 km/300 , 000 k m s = 820 3 s = 273.3 s As the distance is given with 2 significant figures, we round this off to 270 sec = 4 min 30 sec.
