the first step in the mechanism is the acid-catalyzed generation of an enol and then electrophilic addition of bromine and cation is formed because of the destabilization effect of the electronegativity of oxygen
The ability of an atom or functional group to draw electrons to itself is known as an electronegativity in chemistry. An atom's electronegativity is influenced by both its atomic number and how far away from its charged nuclei its valence electrons are located.
The ability of an atom to draw shared electrons in a covalent connection is referred to as electronegativity. The stronger an element attracts the shared electrons, the higher its degree of electronegativity.
The propensity of an atom to attract other atoms when it is combined is known as an element's electronegativity. Additionally, a pair of bound electrons are shared. In contrast, an element's electropositivity refers to an atom's propensity to contribute electrons while also withdrawing from covalent connections.

________ is the enthalpy change when 1 mole of water is produced by the reaction of an acid and a base under standard conditions.
Standard enthalpy change of neutralization is the enthalpy change when 1 mole of water is produced by the reaction of an acid and a base under standard conditions.
Enthalpy change of neutralization:
Every time enthalpy change of neutralization is calculated, one mole of water is produced. Heat is released when an acid and an alkali react, hence enthalpy changes of neutralization are always negative. The values are always quite comparable for reactions involving strong acids and alkalis, falling between -57 and -58 kJ mol-1.If the reaction is the same in each case of a strong acid and a strong alkali, the enthalpy change is similar.Learn more about the Enthalpy of neutralization with the help of the given link:

A moderate antiseptic used topically to treat minor burns, scrapes, and cuts is hydrogen peroxide. As a mouth rinse, it can be used to assist clear mucus or soothe minor oral irritation (caused, for example, by canker/cold sores, or gingivitis).
Stronger than chlorine, chlorine dioxide, and potassium permanganate, hydrogen peroxide is a potent oxidant.
Human blood is exposed to a hydrogen peroxide solution, which causes the peroxide to break down and release oxygen. Before transfusion, this process has been utilized to oxygenate banked blood.
When hydrogen peroxide comes into contact with skin, a chemical process takes place that causes hydrogen peroxide to turn white. When the solution oxidizes, oxygen bubbles that arise give the mixture a white, foamy appearance.

How do I find last significant figure. Please give a thorough explanation because I do not understand this (40 points)
Use 46.7350 as example
Answer:
Below I have listed a write up that helped me!
Explanation:
Here are some general rules regarding significant figures (or sigfigs!)
1) any number that is not a 0 is always a sigfig. In your example, the significant figures would be 4, 6, 7,3,5 and *0. (*there are special rules regarding the number 0)
2) If a 0 is between two non-zero digits (sigfigs), it will be a significant figure. For example, in the number 305, the 0 between the 3 and 5 would be considered a significant figure.
3) 0's that "lead", or are to the left of significant figures are NOT significant figures. For example, in the number 0.002, there would be only one significant figure, which is the 2.
4) 0's that "trail", or are to the right of a significant figure behind a decimal place, are significant figures. For example, in the number 3.1250, the 0 at the end would be considered significant. There are five sigfigs total in this number. The trailing 0 in your example would be significant!
5) However, regarding the rule above, if the number DOES NOT have a decimal place and has trailing 0's, those 0's will not be considered significant figures. For example, in the number 5,320, the 0 at the end would not be significant and there would be three sigfigs in this number.

Explanation:
You can determine the units in the final answer by identifying which of the units cancel out. Units are eliminated (cancelled out) when they are located both in the numerator and denominator of proportions being multiplied.
In this case, these units are cancelled out.....
-----> milligrams (mg) = (1st and 2nd proportions)
-----> decaliters (dL) = (1st and 3rd proportions)
-----> liters (L) = (3rd and 4th proportions)
As these units are not cancelled out, you are left with grams (g) in the numerator and milliliters (mL) in the denominator.
The final units should be represented by:

Why is the citric acid cycle considered part of aerobic metabolism even though oxygen does not appear explicitly in any reaction because?
Succinate dehydrogenase is the citric acid cycle considered part of aerobic metabolism even though oxygen does not appear.
The respiratory complex II, also known as succinate dehydrogenase (SDH), succinate-coenzyme Q reductase (SQR), or SDH, is an enzyme complex that is present in the inner mitochondrial membrane of eukaryotic and numerous bacterial cells. SDH converts succinate to fumarate as part of the citric acid cycle. SDH shares structural similarities with fumarate reductase, an enzyme that catalyzes the reverse process during anaerobic respiration in bacteria. (1997, Hagerhall). Succinic semialdehyde dehydrogenase impairment is brought on by ALDH5A1 gene mutations. Instructions for creating the succinic semialdehyde dehydrogenase enzyme are found in the ALDH5A1 gene.

A single slit with a width of 2019 * 109 m creates its initial minimal for 624 nm light at an angle of 18°.
How does diffraction work?
Waves spreading outward around obstructions are known as diffraction. Diffraction happens with sound, electromagnetic radiation like light, X-rays, and gamma rays, as well as with incredibly minuscule moving particles like atoms, neutrons, and electrons that exhibit wavelike qualities. Diffraction prevents the creation of sharp shadows as one of its effects. In order to spread out and illuminate regions at which a shadow is anticipated, light must be bent around corners, which is known as diffraction.
Calculation:
Provided for a single slit, m=1
λ = 624 *10⁻⁹
sinθ = sin 18⁰
Therefore,
asinθ=mλ
a = [tex]\frac{1 * 624 *10^{-9} }{sin 18}[/tex]

Answer: a. 65.37 mL
b. 5.3 cm
c. 2.08 km (plus) or 1.64 km (minus)
d. 18°C (plus) or 16°C (minus)
Explanation:
The way significant figures work when you're adding or subtracting, is you go to the answer with the least amount of decimal places. Take a. for example; you have 65.316 (3 places after the decimal) and 0.05 (2 places after the decimal place). Based off of this, you would round your answer to two places after the decimal. And when you have a whole number, like in d. you round to the nearest whole number, since there aren't any decimal places to round your answer to.
Rapid breathing pays back the __________ debt by breaking down lactic acid. creatine glycogen oxygen glucose
Rapid breathing pays back the oxygen debt by breaking down lactic acid. creatine glycogen oxygen glucose.
Even after exercise must be finished, the "oxygen debt" could be paid when laborious breathing and an elevated heart rate were needed to eliminate lactic acid and replenish depleted energy stores.
The oxygen debt would be the quantity of oxygen needed to replenish the body's oxygen stores and remove the lactic acid. It can take anywhere between a few hours for little activity and several days after just a marathon when an individual has been exercising to start repaying an oxygen debt.

How to separate oxygen and hydrogen from water?Electrolysis is a promising choice for without carbon hydrogen creation from inexhaustible and atomic assets. Electrolysis is the method involved with utilizing power to part water into hydrogen and oxygen. This response happens in a unit called an electrolyzer. Electrolyzers can go in size from little, apparatus size hardware that is appropriate for limited scope dispersed hydrogen creation to huge scope, focal creation offices that could be tied straightforwardly to sustainable or other non-ozone depleting substance radiating types of power creation.How Does it Work?Like energy components, electrolyzers comprise of an anode and a cathode isolated by an electrolyte. Different electrolyzers capability in various ways, fundamentally because of the different kind of electrolyte material included and the ionic species it conducts.
