Would you expect the product of this experiment to be optically active? If not, could it be resolved into optically active components? Briefly explain.
Bromination of trans-cinnamic acid
Answers
The product can be made optically active by its enantiomers.
Let us understand the reaction.
If the totaling of bromine to cis-cinnamic acid uses the same mechanism or device as the addition to trans-cinnamic acid, addition of bromine only transpires on the top (syn) and not the bottommost face (anti).
So, bromine added to cis-cinnamic only adds to the same face (syn addition) as a result producing only three dibromides. These three dibromides can be kept on different positions which forms enantiomers.
We trans-cinnamic acid with bromine to form 2,3-dibromo-3- phenylpropanoic acid.
Bromination of trans-cinnamic acid can result in the formation of two different pairs of enantiomers.
Since the enantiomers are present it means we can write the product in different ways.
Therefore, the enantiomers of the product, makes the product optically active.

in the krebs citric acid cycle, how much of the original carbonyl carbon from acetyl-coa will remain in oxaloacetate after two full cycles?
Answers
None, it will all be lost as Carbon dioxide.
Krebs or citric acid cycle is also known as The tricarboxylic acid (TCA) cycle.
The main source of energy for cells and an important part of aerobic respiration. Aerobic respiration is the respiration occurs in the presence of oxygen.
This cycle harnesses the available chemical energy of the acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
TCA cycle metabolizes acetate that is derived from carbohydrates, proteins, and fats to form adenosine triphosphate (ATP) which is the body's energy currency.

NH4+ is the conjugate acid of NH3., The formula for the conjugate acid of F− is HF , Cl − Chloride ion for the conjugate acid of HCl.
Why is it called a conjugate acid?A conjugate acid-base pair, according to the Brnsted-Lowry definition of acids and bases, consists of two compounds that vary solely by the presence of a proton (H+). When a proton is given to a base, a conjugate acid is generated, and when a proton is withdrawn from an acid, a conjugate base is formed.A conjugate base, in a broader sense, is the base member, X-, of a pair of compounds that convert into each other by acquiring or losing a proton. In a chemical process, the conjugate base might acquire or absorb a proton. In the reaction, the conjugate acid donates a proton or hydrogen.NH4+ is the conjugate acid of NH3.

Answer:
A conjugate acid is the product that is different from a base by one proton.
Explanation:
What is a conjugate acid Example?
A conjugate acid is the product that is different from a base by one proton. Examples of conjugate acids include water (base) reacting with an acid to form the hydronium ion (conjugate acid), and ammonia (base) reacting with an acid to form the ammonium ion (conjugate acid).
The conjugate of HF:
So as we know, a conjugate base is simply an acid that has given up a proton. In the case of HF (hydrofluoric acid), once it donates the H+ ion/proton, it becomes F- (fluoride ion). The remaining F- is the conjugate base of HF and conversely, HF is the conjugate acid of F-.
The conjugate of HCL:
If a species is classified as a strong acid, its conjugate base will be weak.[3] An example of this case would be the dissociation of hydrochloric acid HCl in water. Since HCl is a strong acid (it dissociates to a great extent), its conjugate base (Cl−) will be a weak conjugate base. Therefore, in this system, most H+ will be in the form of a hydronium ion H3O+
instead of attached to a Cl− anion and the conjugate base will be weaker than a water molecule.
Conjugate base of HCl in the following reaction is: HCl(aq)+H2O→Cl−(aq)+H3O+.
The conjugate of NH:
Normally the conjugate acid of a weak base is a strong acid, however, the conjugate acid of the weak base NH3 is a weak acid, NH4+.A conjugate acid-base pair is an acid-base pair that differs only by one proton.Conjugate acid When a proton is added to a base, a conjugate acid is formed.Conjugate acids have one extra proton compared to the species that is forming it.Conjugate acid of NH3.The given species is ammoniaNH3.The conjugate acid of NH3 is NH4+.

If a molecule has a square planar molecular geometry, what must be its hybridization?.
Answers
The central atom's hybridization must be dsp2 for a square planar form.
What is hybridization?Hybridization is defined as creating new orbitals by combining two or more atomic orbitals, which describes the covalent bonds in molecules. The valence bond hypothesis is expanded in the process of hybridization.
As a result, the two unpaired electrons in orbital 4d are coupled, leaving one empty orbital. In order to produce the dsp2 kind of hybridization and square planar geometry, one orbital each of the 4d, 5s, and 5p participates in the hybridization process.
Thus, the central atom's hybridization must be dsp2 for a square planar form.

On the other hand, helium is a crucial component in several sectors, including high-tech manufacturing, medical technology, space exploration, and national security.
The second most prevalent element in the universe, helium, is scarce on Earth. It is the lightest noble gas, colourless, odourless, inert, and has a low boiling point. It is a byproduct of nuclear fusion and radioactive decay.
Briefing:According to Boyle's Law:
P₁ V₁=P₂ V₂
P₁=1.61atm
