Alcohols are produced via the two step hydroboration-oxidation process. In an Anti-Markovnikov process, the boron connects to the alkene bouble bond's least substituted carbon while the hydrogen (from BH3 or BHR2) attaches to the more substituted carbon.
What is Hydroboration ?A limiting reagent is one that is completely consumed during a reaction, hence restricting the product's yield. Compared to the limiting reagent, the other reactant(s) are present in excess. The amount of product that could be produced based on the molar ratios is known as the theoretical yield. The amount that was actually retrieved is divided by the theoretical yield to determine the percent yield. For this amount to be expressed as a percentage, multiply it by 100.
What is Oxidation procedure ?A chemical process called oxidation occurs. As a result of atoms or groups of atoms losing electrons, it is described as a process. The addition or loss of oxygen or hydrogen in a chemical species is another method to define oxidation. When these things happen, oxidation occurs.
When an atom, molecule, or ion loses one or more electrons during a chemical reaction, oxidation takes place. The chemical species' oxidation state increases while oxidation takes place. Oxygen is not always necessary for oxidation to occur. The phrase was initially used when oxygen produced an electron loss during a process.

The maximum mass of produced will be, 2.16 grams
What is molar mass ?
In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance. This is the number of moles of that sample measured in moles. Molar mass is a mass property, not a molecular property of a substance. Molar mass is the average of many instances of a compound, which often differ in mass due to the presence of isotopes. Most commonly, molar mass is calculated from standard atomic masses, so it is a global average and a function of the relative isotopic abundances of constituent atoms on Earth. Molar mass is good for converting between the mass of a substance and the quantity of a bulk substance.
Mass of Methane = 0.962 g
Mass of oxygen= 1.2 g
Molar mass of Methane= 16 g/mole
Molar mass of Oxygen = 32 g/mole
Molar mass of Water = 18 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
Moles of methane = 0.962 g/16 g/mole=0.060
Moles of oxygen = 1.2 g/32 g/mole=0.04
As, 1 moles of CH₄ react with 2 mole of O₂
So, 0.06 moles of methane react with 2 x 0.04 = 0.08 moles of oxygen
From this we conclude that, Oxygen is an excess reagent because the given moles are greater than the required moles and methane is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of .
As, 1 mole of react to give 2 moles of
So, 0.06 moles of methane react to give 0.06 x 2 = 0.12 moles of
Therefore, the maximum mass of produced will be, 2.16 grams.

What happens to the atp molecule when a phosphate group is removed? (what does it turn into?).
When a phosphate group is removed from an ATP molecule, energy is released.
ATP (adenosine triphosphate) is the energy that powers cellular processes. It can be stored and used at any time for any reaction your cells require. It consists of an adenine base attached to a ribose sugar bound to three phosphate groups that are tightly bound by phosphate anhydride bonds.
When the phosphate group is removed from the ATP molecule, this process is called hydrolysis. During the hydrolysis process, the phosphoanhydride bond is cleaved and ATP is converted to an ADP (adenosine diphosphate) molecule. ADP is converted to AMP (adenosine monophosphate) when another bond is broken. These three types of energy are constantly being interconverted within the cell according to the demands of cellular processes.
When a phosphate group is removed from an ATP molecule, energy is released. Hence, when ADP is formed from ATP by the loss of a phosphate group, energy is released.

Why does the developing chamber need to be prepared before adding the tlc plate?.
In the process of TLC covering the beaker is necessary to ensure that the atmosphere inside is completely saturated with solvent vapour. To aid with this, the beaker is frequently lined with some filter paper that has been dipped in solvent. The solvent won't evaporate as it rises up the plate if there is enough vapour in the beaker to completely fill the atmosphere.
Describe chromatography.
Chromatography is a technique for decomposing mixtures of substances into their constituent parts. The same idea underlies all chromatographic techniques. The stationary phase of all of them is either a solid or a liquid supported by a solid, and the mobile phase is present (a liquid or a gas). The stationary phase is traversed by the mobile phase, which transports the mixture's constituents along with it. The speed of various components varies.Thin film chromatography, often known as TLC, is a quick, easy, and affordable process that provides chemists with an immediate answer regarding the number of components in a combination. When a compound's Rf is compared to the Rf of another compound that is known to be in the mixture, TLC is also utilized to support the identity of that compound.
Setting up the development container
The container used for TLC development can be a specifically constructed chamber, a jar with a lid, or a beaker with a watch glass on top (the latter is used in the undergrad labs at CU). Just under 0.5 cm of solvent should be poured into the chamber. You can line a portion of the inside of the beaker with filter paper to help with the solvent vapour saturation of the TLC chamber. The beaker should be covered with a watch glass, gently stirred, and left to stand while you make your TLC dish.

The mole fraction of acetyl bromide in this solution is 0.39.
Calculation:-
The molar mass of CH3COBr,
MM = 2*MM(C) + 3*MM(H) + 1*MM(O) + 1*MM(Br)
= 2*12.01 + 3*1.008 + 1*16.0 + 1*79.9
= 122.944 g/mol
Molar mass of C6H6,
MM = 6*MM(C) + 6*MM(H)
= 6*12.01 + 6*1.008
= 78.108 g/mol
n(CH3COBr) = mass/molar mass

The mole fraction or the molar fraction is defined as the unit of amount of the substances, divided by the total amount of all the substances that are present in the mixture. The formula for it is given below;
[tex]X_{A}[/tex] = [tex]N_{A}[/tex] ÷ [tex]N_{A}[/tex] + [tex]N_{B}[/tex] (Where N represents the number of moles of A and B respectively)
Vapor pressure is defined as the pressure that is exerted by a vapor which is in equilibrium with its condensed phase at a given temperature in a closed system.
In the above given question we need to find out the vapor pressure of KCl where vapor pressure of water is given, so we use the following method to solve this question;
[tex]N_{A}[/tex] = weight of water = 250 = 13.88
Molecular mass 18
[tex]N_{B}[/tex] = weight of KCl = 25 = 0.335
Molecular mass 74.55
So, [tex]X_{A}[/tex] = 13.88 = 0.976 [[tex]P_{o}[/tex] = 23.76]
13.88 + 0.335
We know that P = [tex]P_{o}[/tex][tex]X_{A}[/tex]
P = 23.76 × 0.976 ⇒ 23.189

If the concentration of NaCl is 7.61 m, when it begins to crystallize out of solution, then the Ksp is 57.91.
The dissociation reaction of NaCl is given as:
NaCl → Na⁺ + Cl⁻
7.61 7.61
The Ksp for the following is given as :
ksp = [Na⁺] [Cl⁻]
⇒ksp = 7.61 × 7.61
⇒ksp = 57.91
When a solid substance dissolves into an aqueous solution, it posses a equilibrium constant which is known as solubility product constant, Ksp. The solubility product constant Ksp increases with increase in temperature and with increase in the solubility.
Thus, If the concentration of NaCl is 7.61 m, when it begins to crystallize out of solution, then the ksp is 57.91 .
