Draw curved arrows to show electron reorganization for the mechanism step below. (For a resonance-stabilized anion, draw a single resonance form with the negative charge on oxygen, not on carbon.) Make the ends of your arrows specify the origin and destination of reorganizing electrons.

Answers

Answer 1

Answer:

Explanation:

Dear student, this question appears to be incomplete but in the diagram attached below, I have carefully drawn out the required organic structure.

The aim of this question is to show the mechanism of the given structure and to point out the resonance structure.

The first diagram shows the complete part (i.e. the structure of the organic compound) and its major product(answer).

The second diagram shows the mechanism by which we arrived at the major product.

From the second diagram attached below, the -oxo substituent of the methanol attacks the hydrogen atom as shown below, leading to the formation of the enolate ion (a resonance stabilized anion).

However, this is because the alpha carbon attaches to the hydrogens readily leaves as H⁺ to yield an enolate ion as a result of -C- that is doubly bonded to oxygen (an Electron withdrawing group).

Kindly check out the images attached below to see the mechanism.

What volume (in mL) of 0.3900 M HCl is required to neutralize 50.00 mL of 0.8000 M NaOH?

Answers

Answer:

102.6 mL

Explanation:

The reaction that takes place is:

NaOH + HCl → NaCl + H₂O

First we calculate how many NaOH moles are there in 50.00 mL of a 0.8000 M solution:

0.8000 M * 50.00 mL = 40 mmol NaOH

Then we convert NaOH moles into HCl moles:

40 mmol NaOH * [tex]\frac{1mmolHCl}{1mmolNaOH}[/tex] = 40 mmol HCl

Finally we calculate the volume of a 0.3900 M solution would contain 40 milimoles:

40 mmol / 0.3900 M = 102.6 mL

Balance the following equations:
1) C2H402+_02->_C02+ _H20
2) V205+ _CaS→_Ca0+ V2S5

3) S8+_O2->_SO2

Answers

Answer:

1) 0 C2H4O2 + 0 O2 -> 0 CO2 + 0 H2O (balanced)

2) V2O5 + CaS -> CaO + V2S5

just additional info: V2O5 is divanadium pentaoxide

LHS (Left hand side)

V: 2

O: 5

Ca: 1

S: 1 x 5 [to balance with the right hand side of the equation]

RHS (Right hand side)

V: 2

O: 1 x 5 [to balance with the left hand side of the equation]

Ca: 1

S: 5

When you balance any elements, you have to balance the whole chemical compound.

Thus,

V2O5 + 5 CaS -> 5 CaO + V2S5

LHS CHECK:

V: 2

O: 5

Ca: 5

S: 5

RHS CHECK:

V: 2

O: 5

Ca: 5

S: 5

3) S8 + O2 -> SO2

LHS:

S: 8

O: 2

RHS:

S: 1 x 8 [to balance with LHS]

O: 2

When you balance any elements, you have to balance the whole chemical compound.

S8 + O2 -> 8 SO2

When we add 8 to the RHS, it gives us 8S, 16 O.

In order to balance that into the RHS, I need to multiply the O2 by 8, which will give 8(O2) = 16 O particles.

Therefore, S8 + 8 O2 -> 8 SO2 is the final answer for (3).

Examination of the first few successive ionization energies for a given element usually reveals a large jump between two ionization energies. For example, the successive ionization energies of magnesium show a large jump between IE2 and IE3. The successive ionization energies of aluminum show a large jump between IE3 and IE4. Explain why these jumps occurs and how you might predict them.

Answers

Answer:

See Explanation

Explanation:

Ionization energy refers to the energy required to remove an electron from an atom. Metals have lower ionization energy than non metals since ionization energy increases across a period.

One thing that we must have in mind is that it takes much more energy to remove an electron from an inner filled shell than it takes to remove an electron from an outermost incompletely filled shell.

Now let us consider the case of magnesium which has two outermost electrons. Between IE2 and IE3 we have now moved to an inner filled shell(IE3 refers to removal of electrons from the inner second shell) and a lot of energy is required to remove an electron from this inner filled shell, hence the jump.

For aluminium having three outermost electrons, there is a jump between IE3 and IE4 because IE4 deals with electron removal from a second inner filled shell and a lot of energy is involved in the process hence the jump.

Hence a jump occurs each time electrons are removed from an inner filled shell.

Explanation:

Heat is a reactant.

If the equation requires heat to occur, the reaction is endothermic

The equation would have this model

A + B + heat =====> C + D

If the equation gives away heat, then it is exothermic

The equation would look like this. (I'll use a common reaction)

Explanation:

Neutralization or acid base reaction is a chemical reaction in which acid and base combine to form salt and water. Acids donate [tex]H^+[/tex] ions and bases donate [tex]OH^-[/tex] ions  in water which combine to form water molecules.

The balanced chemical reaction for the given reaction is ;

[tex]HCl+NaOH\rightarrow NaCl+H_2O[/tex]

Thus the missing product is NaCl.

The missing product in the acid-base reaction is NaCl.

The balanced chemical reaction for the given reaction is ;

[tex]HCl +NaOH[/tex] → [tex]NaCl +H_20[/tex]

What is an acid-base reaction?

When acid and base react with each other they form salt and water. Water and salt both are neutral which means, whenever acid and base react together, they are neutralized by each other.

Neutralization or acid base reaction is a chemical reaction in which acid and base combine to form salt and water.

Acids donate  [tex]H^{+}[/tex] ions and bases donate  [tex]0H^{-}[/tex] ions in water which combine to form water molecules.

Since acid and base neutralize each other's effect,it is called neutralization reaction.

For Example: When Sodium Hydroxide ( NaOH) , a base, reacts with Hydrochloric acid (HCl) , it forms the salt, Sodium Chloride (NaCl) and Water.

The balanced chemical reaction for the given reaction is ;

[tex]HCl +NaOH[/tex] → [tex]NaCl +H_20[/tex]

(Show work pls :)!)

Answers

Answer:

485 K

Explanation:

Step 1: Given data

Initial pressure (P₁): 125 atmInitial temperature (T₁): 303 KFinal pressure (P₂): 200 atmFinal temperature (T₂): ?

Step 2: Calculate the final temperature of the gas

Assuming constant volume and ideal behavior, we can calculate the final temperature of the gas using Gay Lussac's law.

P₁/T₁ = P₂/T₂

T₂ = P₂ × T₁/P₁

T₂ = 200 atm × 303 K/125 atm = 485 K

3. The activation energy of the forward reaction is 200 KJ.

4. The activation energy of the reverse reaction is 150 KJ.

5. The energy of the forward reaction is +50 KJ

6. The energy of the reverse reaction is –50 KJ

7. Endothermic reaction

8. Exothermic reaction

Explanation:

1. Determination of the energy of reactant.

From the diagram given above, the energy of the reactant is 50 KJ

2. Determination of the energy of product.

From the diagram given above, the energy of the product is 100 KJ.

3. Determination of the activation energy of the forward reaction.

The activation energy is the energy between the reactant and the peak. It can be obtained as follow:

Energy of reactant (Eᵣ) = 50 KJ

Energy at the peak (Eₕ) = 250 KJ

Activation energy (Eₐ) =?

Eₐ = Eₕ – Eᵣ

Eₐ = 250 – 50

Eₐ = 200 KJ

Thus, the activation energy of the forward reaction is 200 KJ

4. Determination of the activation energy of the reverse reaction.

Energy of reactant (Eᵣ) = 100 KJ

Energy at the peak (Eₕ) = 250 KJ

Activation energy (Eₐ) =?

Eₐ = Eₕ – Eᵣ

Eₐ = 250 – 100

Eₐ = 150 KJ

Thus, the activation energy of the reverse reaction is 150 KJ

5. Determination of the energy of the forward reaction.

Energy of reactant (Eᵣ) = 50 KJ

Energy of product (Eₚ) = 100 KJ

Enthalpy change (ΔH) =?

ΔH = Eₚ – Eᵣ

ΔH = 100 – 50

ΔH = +50 KJ

Thus, the energy of the forward reaction is +50 KJ

6. Determination of the energy of the reverse reaction.

Energy of reactant (Eᵣ) = 100 KJ

Energy of product (Eₚ) = 50 KJ

Enthalpy change (ΔH) =?

ΔH = Eₚ – Eᵣ

ΔH = 50 – 100

ΔH = –50 KJ

Thus, the energy of the reverse reaction is –50 KJ

7. The forward reaction is endothermic reaction because the energy of the product is higher than the energy of the reactant which leads to positive energy of the forward reaction (+50 KJ).

8. The reverse reaction is exothermic reaction because the energy of the product is lesser than the energy of the reactant which leads to negative energy of the reverse reaction (–50 KJ). In a nut shell, we can say that the energy of the reverse reaction is exothermic because its energy of reaction is –50 KJ.
