The carbonyl carbon in a ketone is attacked primarily by the peroxy oxygen bonded to hydrogen as opposed to the peroxy oxygen bonded to carbon because:

Answers

Answer:

This is because peroxy oxygen bonded to hydrogen can easily undergo nucleophilic protonation with the carbonyl carbon to form an alcohol

Explanation:

A ketone is a functional group that contains a carbonyl group (carbon-oxygen double bond ( R1R2-C=O).

The carbonyl carbon doubly bonded to the oxygen is electron deficient as a result of difference in electronegativity between carbon and oxygen, hence is susceptible to nucleophilic attacks

R1R2 - C = O

where R1 and R2 are organic substituents.

The peroxy oxygen that is bonded to hydrogen (H -O-O-R) is the electron-rich centre and easily attacks electron-deficient centres like the carbonyl carbon in ketones to form an alcohol.

The bond between the hydrogen attached to the peroxy oxygen is broken and the resultant hydrogen ion undergoes protonation with the oxygen of the carbonyl group to form an alcohol

R1R2 - C = O + H - O-O - R =>

R1R2- CH - OH + R - O-O-R1

Write a balanced chemical equation based on the following description: iron metal reacts with oxygen gas to produce solid iron (III) oxide.

Answers

Answer:

4 Fe  +   3 O2    ⇒  2  Fe2O3

Explanation:

iron metal reacts with oxygen gas to produce solid iron (III) oxide.

Fe   +   O2  ⇒  Fe2O3

4 Fe  +   3 O2    ⇒  2  Fe2O3

The balanced chemical equation for the reaction is

4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)

From the question,

We are to write a balanced chemical equation for the reaction of iron metal with oxygen gas to produce solid iron (III) oxide

Iron metal is represented as Fe(s)

Oxygen gas is represented as O₂(g)

and Solid iron (III) oxide is represented as Fe₂O₃(s)

Now, we will write the balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)

This means 4 moles of the iron metal reacts with 3 moles of oxygen gas to produce 2 moles of solid iron (III) oxide.

Hence, The balanced chemical equation for the reaction is

4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)

What mass of N2O5 will result from the reaction of 6.0 mol of NO2 if there is a 61.1% yield in the reaction

Answers

Answer:

2.0 × 10² g

Explanation:

Step 1: Write the balanced equation

2 NO₂ + 0.5 O₂ ⇒ N₂O₅

Step 2: Calculate the theoretical yield, in moles, of N₂O₅

The molar ratio of NO₂ to N₂O₅ is 2:1.

6.0 mol NO₂ × 1 mol N₂O₅/2 mol NO₂ = 3.0 mol N₂O₅

Step 3: Calculate the theoretical yield, in grams, of N₂O₅

The molar mass of N₂O₅ is 108.01 g/mol.

3.0 mol × 108.01 g/mol = 3.2 × 10² g

Step 4: Calculate the real yield, in grams, of N₂O₅

real yield = theoretical yield × percent yield

real yield = 3.2 × 10² g × 61.1% = 2.0 × 10² g

How many ATP molucules may by synthesed in the case of full methabolism in MUSCULE of oligosaccharide which molucular weight is 48942?

Answers

Answer:

About 96 to 256 ATP molecules are produced.

Explanation:

About 96 to 256 ATP molecules may be synthesized in the full metabolism in oligosaccharide because one oligosaccharide molecule has 3 to 8 glucose atoms. About 30 to 32 ATP are produced from one glucose molecule so from three glucose molecule, 96 ATP produced whereas 256 ATP molecules are produced from 8 glucose molecules so we can say that About 96 to 256 ATP molecules from one oligosaccharide.

When triglycerides are metabolized, ___ is/are converted to pyruvate or glucose, whereas ____ is/are converted to acetyl CoA.

Answers

Answer:

Glycerol;Pyruvate

Explanation:

Metabolism of triglycerides occur through a process known as lipolysis. During triglyceride metabolism, Glycerol is converted to pyruvate or glucose through glycolysis or gluconeogenesis respectively. Glycerol enters these pathways by being converted to glycerol-3-phosphate (reaction catalyzed by glycerol kinase) which can in turn be converted to dihydroxyacetone phosphate (reaction catalyzed by glycerol-3-phosphate dehydrogenase).

NOTE: Dihydroxyacetone phosphate is a compound/substrate found in both glycolysis and gluconeogenesis.

The end product of glycolysis is pyruvate; this pyruvate, under aerobic condition is converted to acetyl coA (reaction catalyzed by pyruvate dehydrogenase complex), an intermediary of the Tricarboxylic acid cycle.

6. Sometimes a tire that appears to be fine may be unsafe because: A. There may be perforations too small to see B. The manufacturing date may be incorrect C. Chemical reactions may have deteriorated the rubber

Answers

Answer:

C. Chemical reactions may have deteriorated the rubber

Explanation:

A tire ages with time and most of the time this happens due to chemical reactions in the rubber parts. This could happen faster due to heat and sun.

As a tire is deteriorating or aging, a chemical change happens. What happens is that more chemical bonds are going to be produced with time between the molecules. We call this the process of oxidation. This actually bad for the tire, because the rubber would turn out to be stuffs d strong causing the tires thread to separate and also disintegration would occur.

The combustion of gasoline produces carbon dioxide and water. Assume gasoline to be pure octane (C8H18) and calculate the mass (in kg) of carbon dioxide that is added to the atmosphere per 1.0 kg of octane burned

Answers

Answer:

3.1 kg

Explanation:

Step 1: Write the balanced combustion equation

C₈H₁₈ + 12.5 O₂ ⇒ 8 CO₂ + 9 H₂O

Step 2: Calculate the moles corresponding to 1.0 kg of C₈H₁₈.

The molar mass of C₈H₁₈ is 114.23 g/mol.

1.0 × 10³ g × 1 mol/114.23 g = 8.8 mol

Step 3: Calculate the moles of CO₂ produced from 8.8 moles of C₈H₁₈

The molar ratio of C₈H₁₈ to CO₂ is 1:8. The moles of CO₂ produced are 8/1 × 8.8 mol = 70 mol.

Step 4: Calculate the mass corresponding to 70 moles of CO₂

The molar mass of CO₂ is 44.01 g/mol.

70 mol × 44.01 g/mol = 3.1 × 10³ g = 3.1 kg

During an experiment, solid iodine was placed in a sealed container. The container was gradually heated and purple-colored vapors of iodine formed were observed. Describe this system when it reaches phase equilibrium.

Answers

Answer:

See explanation

Explanation:

A system is said to have attained dynamic equilibrium when the rate of forward reaction and the rate of reverse reaction are equal.

Considering the system under consideration;

I2(s)⇄I2(g)

Heating the container converts solid iodine to purple coloured iodine vapour.

At equilibrium, there will be no net change in the amount of solid iodine and iodine vapour present in the system because the two processes (forward and reverse reactions) occur at the same rate at equilibrium.

hat is the molarity of a solution prepared by dissolving 12.0 g of ethylene glycol, C2H6O4, in water to make 250.0 mL of solution

Answers

Answer:

0.512 M

Explanation:

We'll begin by calculating the number of mole in 12 g of C₂H₆O₄. This can be obtained as shown below:

Mass of C₂H₆O₄ = 12 g

Molar mass of C₂H₆O₄ = (2×12) + (6×1) + (4×16)

= 24 + 6 + 64

= 94 g/mol

Mole of C₂H₆O₄ =?

Mole = mass /molar mass

Mole of C₂H₆O₄ = 12 / 94

Mole of C₂H₆O₄ = 0.128 mole

Next, we shall convert 250 mL to L. This can be obtained as follow:

1000 mL = 1 L

Therefore,

250 mL = 250 mL × 1 L / 1000 mL

250 mL = 0.25 L

Thus, 250 mL is equivalent to 0.25 L.

Finally, we shall determine the molarity of the solution. This can be obtained as follow:

Mole of C₂H₆O₄ = 0.128 mole

Volume = 0.25 L

Molarity =?

Molarity = mole /Volume

Molarity = 0.128 / 0.25

Molarity = 0.512 M

Thus, the molarity of the solution is 0.512 M

What are two factors that determine the concentration of hydronium (or hydroxide) ions in an acid (or base) solution?

Answers

Answer:

hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes, and specific vocabulary has been developed to describe these concentrations in relative terms. A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.

Calculate the height of a column of ethanol (C2H5OH) that would be supported by atmospheric pressure. The density of ethanol is 0.789 g/cm3.

Answers

Answer:

The height of a column of ethanol is 13.1m

Explanation:

we begin by converting the density to SI unit= 0.789g/cm3* 1kg * [tex]100^{3}[/tex]* [tex]cm^{3}[/tex]

                                                                               cm * 1000g * [tex]1^{3}m^{3}[/tex]

                                                            = 789kg/m3

converting pressure to SI unit= 1 atm =101325 Pa

hence P= hdg

g= 9.81 m/s2

making h the subject of the formula

h= P/dg

h= 101325Pa/ 789kg/m3 * 9.81 m/s2

h= 13.1m

Answer: PLATOIn two speeches, delivered 150 years apart, two activists use rhetoric to advocate for basic human dignity. Here is how their rhetorical strategies compare.Stantons Logos Appeal. In A Plea for the Oppressed, Lucy Stantons purpose is to convince her audience that the fight to end to slavery is their fight. One of most effective parts of her speech is her logos appeal to reformers in the audience, such as those in the peace movement. She connects their cause to the cause of abolition in a powerful extended metaphor that begins, Slavery is the combination of all crime. It is War. Showing the logical connection between war and slavery makes it difficult for peace activists to fail to support abolition.Lewiss Ethos Appeal. Representative John Lewiss purpose in his speech at the King Memorial groundbreaking is to remind the nation that Kings work is unfinished. His primary appeal is ethos. He is able to make this appeal by drawing on his position as a popular representative, a leader of the civil rights movement, and a personal friend of Martin Luther Kings. In a series of parallel phrases, Lewis establishes that he and King were very close. The anecdote Lewis recalls about being a teenager in the segregated South, and the impact of hearing King on the radio, adds a strong emotional appeal to the ethical one as Lewis calls for the next generation to carry on Kings legacy. He is uniquely qualified to commemorate King.The different appeals each speaker emphasizes reflects their status. Stanton was young graduate, and Lewis was a revered politician. Both weave all three appeals into their speeches, but only Lewis can lean heavily on the ethical appeal. Mt cc th ca mt loi sinh vt khi gim phn to giao t.
