To break a chemical bond, particles need to collide with a certain amount of ____?

[ad_1]

Explanation:

To break a chemical bond, it is required that particles must have certain amount of energy so that when they can collide with each other due to this energy.

Therefore, there will exist a certain amount of force between the particles which will help in breaking the chemical bond.

This energy due to the motion of particles is known as kinetic energy.

Thus, we can conclude that to break a chemical bond, particles need to collide with a certain amount of kinetic energy.

PLEASE HELP Mr. Utterson the lawyer was a man of a rugged countenance, that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary, and yet somehow lovable. At friendly meetings, and when the wine was to his taste, something eminently human beaconed from his eye; something indeed which never found its way into his talk, but which spoke not only in these silent symbols of the after-dinner face, but more often and loudly in the acts of his life. He was austere with himself; drank gin when he was alone, to mortify a taste for vintages; and though he enjoyed the theatre, had not crossed the doors of one for twenty years. But he had an approved tolerance for others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove. "I incline to, Cain's heresy*," he used to say. "I let my brother go to the devil in his quaintly 'own way.'" In this character, it was frequently his fortune to be the last reputable acquaintance and the last good influence in the lives of down-going men. And to such as these, so long as they came about his chambers, he never marked a shade of change in his demeanour. No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature. It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt, the bond that united him to Mr. Richard Enfield, his distant kinsman, the well-known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull, and would hail with obvious relief the appearance of a friend. For all that, the two men put the greatest store by these excursions, counted them the chief jewel of each week, and not only set aside occasions of pleasure, but even resisted the calls of business, that they might enjoy them uninterrupted. *The biblical story of Cain and Abel is a story about two brothers who gave offerings to God. Abel’s offering was accepted by God, but Cain’s was not. Jealous, Cain killed his brother. When God asked Cain where Abel was, Cain said, “Am I my brother’s keeper?” By saying this, Cain implied that what his brother did was his own business. (Genesis 4:1-16) What is significant about “Cain’s heresy” in this passage? A.It shows that Mr. Utterson is a deeply religious and righteous person.

What atomic or hybrid orbitals make up the sigma bond between br and f in bromine trifluoride, brf3?

[ad_1]

Answered by answersmine AT 22/10/2019 – 05:32 AM

Draw the Lewis structure. Bromine has 3 bonds and two lone pairs for a trigonal bipyramidal electron geometry and an sp^3d hybridization. Fluorine is peripheral it does not require hybridization, but we often consider it to be hybridized too – it has 1 bond and 3 lone pairs for sp^3 hybridization. So the sigma bonds come from an overlap of an sp^3d orbital on Br with an sp^3 orbital on F. If you don’t consider the F to be hybridized the overlap would have to be to a p orbital on the F

Which excerpt from The Great Gatsby best indicates that Nick is not fully content with his life? He didn’t say any more, but we’ve always been unusually communicative in a reserved way, and I understood that he meant a great deal more than that. Father agreed to finance me for a year, and after various delays I came East, permanently, I thought, in the spring of twenty-two. Instead of being the warm center of the world, the Middle West now seemed like the ragged edge of the universe—so I decided to go East and learn the bond business.

Here are a few pointers; hope this is useful)

Ovation-by definition- is show of appreciation from an audience, for a person’s accomplishments or flaw.

“Everyone deserves a standing ovation because we all overcometh the world.”

A person’s accomplishment could be how they made a positive change in this world, strong leadership- that makes them a effective leader or simply helping others. A person’s flaw- mistakes in life, sin or even guilt should also be considered an appreciation- an ovation for representing mankind’s flaw and that humanity makes mistakes, fulfilling at least one deadly sin such as greed, lust, selfishness etc.

Thus, regardless of a person’s achievement or flaw- a person deserves an applause for, not the least, living in this society and this world that we are all living together and dying together.

That was just the introduction.. the best part is yet to come.. now it’s your turn!!

Here are other pointers to talk about in your essay:

Shakespeare’s famous line “All the World’s a stage. That agrees with your line: “Everybody deserves a standing ovation…”

Shakespeare explains that men and women are like players: they live, and die, some being celebrated and some forever living in solitude till their death. Shakespeare states the world is a “stage” which symbolizes that mankind is in its peak. The world is changing everyday: little by little and humanity is falling behind.
Due to our world turning into machinery: factories, an automotive future: where humans only job to live (entrance) and to die (exit) the famous humans remembered and the flawed not recalled.

This is according to Shakespeare’s imagery.

I don’t know what grade your in, but I think simplifying Shakespeare’s word of mouth in your essay would be handy and useful as it has strong references of your quote, and agrees strongly in your essay.

Hope this helps 🙂

A bond has a $1,000 face value, a market price of $1,045, and pays interest payments of $74.50 every year. what is the coupon rate?

[ad_1]

The Contribution Margin per unit (CM) can be calculated
from the difference of Selling Price per unit (SP) and Total Expenses per unit
(TE).

 

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = $1,043,400 / 22,200 units sold

SP = $47

 

Second, calculate all expenses:

Direct materials per unit = $234,948 / 27,970 units
manufactured = $8.4

Direct labor per unit = $131,459 / 27,970 units
manufactured = $4.7

Variable manufacturing overhead per unit = $240,542 / 27,970
units manufactured = $8.6

Variable selling expenses per unit = $113,220 / 22,200
units sold = $5.1

TE = $26.8

 

Therefore the CM is:

CM = SP – TE

CM = $47 – $26.8

CM = $20.2 per unit

In the covalent bond between hydrogen and chlorine in the HCl molecule, where will the majority of shared electrons be found? A.near the hydrogen atom B.near the chlorine atom C.equidistant from both atoms D.away from chlorine atom E.away from both atoms

[ad_1]

When ammonia is added with water, it forms a lonely OH- ion and a conjugate acid of HNH3+, or NH4+. Just based on the formula alone, a basic hydroxide is one of the products from NH3 and H2O, which is usually a tall-tale sign of NH3 being basic. Also, the reaction can also be reversed, so that (OH-)+(NH4+) -> H2O+NH3.

If this question has a different chemical formula, with either a H+ (hydrogen atom/proton) or a H3O+ (hydronium) as one of the products, then the compound that is being hydrolyzed (H2O is added to it) is acidic.

Hope this answers the question.

What is the best definition of polar covalent bond?

[ad_1]

Answer: The correct answer is Option B.

Explanation:

A covalent bond is formed when sharing of electrons takes place between the atoms combining. The atom which attracts the shared pair of electron towards itself is more electronegative and the atom which does not attracts the shared pair of electron towards itself is less electronegative.

In HCl molecule, more electronegative atom is chlorine atom having an electronegativity of 3.16 and hydrogen has an electronegativity of 2.1

So, majority of shared electrons will be found near to the chlorine atom in hydrochloric molecule.

Hence, the correct answer is Option B.

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

Which Which of the following elements would most likely become a negative ion when forming a chemical bond? A.carbon B.nitrogen C.aluminum D.chlorine

[ad_1]

Answer:

For isotope we can say

Atomic Number = Number of protons = 7

Number of neutrons = 10

So isotope is given as X-17

Explanation:

As we know that isotope is defined as the atoms which have same number of protons but different number of Neutrons

So isotopes must have same atomic number or same number of protons

But since they have different neutrons so they must have different mass number

So here we can say

it must have atomic Number = Number of protons = 7 protons

Number of Neutrons = 10

Mass Number = Number of Neutrons + number of protons

Mass Number = 7 + 10 = 17

So it is given as X-17

When two atoms have similar electronegativity values and neither atom is strong enough to pull an outer electron from the other atom, what is the resulting bond of these outer electrons? ionic covalent hydrogen metallic

[ad_1]

Answer:

B. The atom has more than eight valence electrons before bonding.

Explanation:

Expansion of the octet rule occurs only with atoms of non-metallic elements from the third period onwards, ie having three or more electronic layers. This is because these atoms have empty orbitals that can accommodate 10, 12 or more electrons. These atoms have more than eight valence electrons before bonding.

An example of a chemical element whose atoms may contract is phosphorus (P), which belongs to family 15 or VA of the periodic table. This means that it has five electrons in the valence shell and, according to the octet theory, should receive three more electrons to be stable with eight electrons.  However, the phosphorus is the element can be the central element of a compound and for this reason it makes five covalent bonds with four carbon atoms. Since the phosphorus atom shares five pairs of electrons, it has a total of ten electrons in the valence shell, meaning it did not follow the octet rule, but there was an expansion of its octet.

The Lewis formula is structural representation that indicates the bonding between atom of a molecule by line and dots used to indicates the electron position around the atoms, electron pair is known as lone pair of electrons shown by pair of dots. The electrons indicated in the structure are valence electrons.

The given atoms are N (g) and O (g).

N (g), whose atomic number is 7.

Electronic configuration for N (g) is 2, 5.

Number of valence shell electrons for N (g) is 5.

O (g), whose atomic number is 8.

Electronic configuration for O (g) is 2, 6.

Number of valence shell electrons for O (g) is 6.

The Lewis formula for N (g)  and O (g) is shown in the image.

The atoms combine to form molecule in order to complete their octet that is to get 8 electrons in their valence shell and get stabilize in nature.

The total number of valence shell electrons in NNO(g) is:

2(5)+6 = 16 electrons

The distribution of electrons in the atom will take place in such a way that formation of triple bond will take place between two nitrogen atoms and a single bond will form between nitrogen and oxygen atom. In order to complete their octet, the nitrogen atom in center will possess 1+ formal charge and oxygen will possess 1- charge (oxygen is  electronegative atom). Thus, results in formation of neutral molecule.

The formal charge on each atom is calculated using:

Valence electrons - Nonbonding electrons - frac{Bonding electrons}{2}

Answer : The mass methane required is, 25 g

Explanation : Given,

Mass of oxygen gas = 100 g

Molar mass of oxygen gas = 32 g/mole

Molar mass of methane gas = 16 g/mole

First we have to calculate the moles of O_2.

text{Moles of }O_2=frac{text{Mass of }O_2}{text{Molar mass of }O_2}=frac{100g}{32g/mole}=3.125moles

Now we have to calculate the moles of CH_4.

The balanced chemical reaction is,

CH_4+2O_2rightarrow CO_2+2H_2O

From the balanced reaction we conclude that

As, 2 moles of O_2 react with 1 mole of CH_4

So, 3.125 moles of O_2 react with frac{3.125}{2}=1.563 moles of CH_4

Now we have to calculate the mass of CH_4

text{Mass of }CH_4=text{Moles of }CH_4times text{Molar mass of }CH_4

text{Mass of }CH_4=(1.563mole)times (16g/mole)=25.008g=25g

Therefore, the mass methane required is, 25 g
