which is the strongest gravitational pull on earth,the sun or the moon why

The Calvin cycle must occur before one molecule of g3p can leave is 3.

Making a G3P molecule requires three Calvin cycles allowing the G3P molecule to exit the cycle and continue making glucose. He needs all three requirements: chlorophyll pigment, chloroplast "theater", and enzyme catalysis. The first stage converts light energy into chemical energy, which is stored in ATP and NADPH molecules until this point.

In the second step of the Calvin Cycle, the carbon-fixed 3-PGA molecule is converted to the monosaccharide molecule, glyceraldehyde-3-phosphate. This stage uses energy from ATP and NADPH produced in the light-dependent reactions of photosynthesis. The Calvin Cycle harnesses the chemical energy of ATP and reduces the power of NADPH from a light-dependent reaction to produce a tricarbonate.

The reaction would take place with racemization. Option C.

The reaction between (s)-3-Bromo-3-methyl hexane and water is a nucleophilic substitution reaction as the leaving group present on the substrate is displaced by a nucleophile. Water is a polar protic solvent and he prefers SN1 reactions over SN2 reactions. Therefore, the reaction mechanism is SN1.

The carbocation and its substituents are all in the same plane. In other words, the nucleophile can attack from either side. As a result, both enantiomers are formed in the SN1 reaction, producing a racemic mixture of both enantiomers. Alkenes react with pure liquid bromine at low temperatures or with solutions of bromine in organic solvents such as carbon tetrachloride.

Answer:The Letter J on the Periodic Table. The letter J was the element symbol for iodine in Mendeleev's 1871 periodic table. You won't find the letter “J” on the IUPAC periodic table of the element

Explanation:

There is no such element beginning with J in the periodic table.

What is an element?

A chemical element is a type of atom with a particular number of protons in the nucleus, such as the specific compound made up entirely of that species. Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is an element's defining attribute, and it is symbolised by the symbol Z - all atoms with the same atomic number are atoms of the same element. Atoms are rearranged into new compounds linked together by chemical bonds when various elements undergo chemical reactions.

The limiting reactant would be Aluminium here.                                      

Here,

                               107.92 g Al would be required  =  96 g of O₂

Therefore,

                         82.49 g of Al might require  =  x g of O₂

Solving for x,

                                   x  =  (82.49 g × 96 g) / 107.92 g

                                   x  =  73.37 g of O₂

The mass of the excess reactant present in the vessel when the reaction is completed is 73.37g.

But,

 [tex]O_{2}[/tex]  is supplied in excess, as we get 117.65 g of it, and 44.28 g of it will not be reacted.

The amount of [tex]Al_{2}O_{3}[/tex]  formed would be solved as,

107.92 g of Al produced in reaction  =  203.92 g of [tex]Al_{2}O_{3}[/tex]

Then,

                     82.49 g of Al would produce  =  x g of [tex]Al_{2}O_{3}[/tex]

Solving for getting x,

                                         x =  (82.49 g ×  203.92 g) / 107.92

                                         x  =  155.86 g of [tex]Al_{2}O_{3}[/tex]

Therefore the mass of aluminum oxide formed would be 155.86g.

%yield= (experimental mass of product/theoretical mass of product)×100

The theoretical mass of the product is already calculated above which is 155.86g and the experimental mass of the product is given as 120g. Therefore,

Answer:

Measurements have shown that the concentration of salt in seawater is 35.5 g-L. Calculate the volume in liters of seawater that must be evaporated to recover 0.400 kg of salt. Be sure your answer has the correct number of significant digits

The concentration of a solution can be expressed in several methods like molarity, molality, mass percentage, etc. The volume in liters of the seawater is  11.267 L.

The measure of the capacity that an object holds is defined as the volume. If a beaker can hold 100 mL water then its volume is 100. The ratio of the mass to density of a substance is the volume.

It can be expressed in mL, L, m³, cm³, etc. The SI unit of volume is m³. The equation used to determine the volume is:

Volume = Mass / Density

1 kg = 1000 g

0.400 kg = 0.400 × 1000 = 400 g

Then the volume in liters of seawater that must be evaporated to recover 0.400 kg of salt is:

V = 400/35.5 = 11.267 L

Thus the volume of seawater is 11.267 L.

The optical brightener absorbs the UV rays.

What is optical brighteners?

Because of the way they reflect light, optical brightening, also known as optical bleaches, are finishes that produce the appearance of extreme whiteness and brightness. These substances contain fluorescent colorless dyes, which increases the reflection of blue light.

What is reflection?

When light reflects off of something, it happens. The light will reflect at the same angle from a smooth and shining surface, such as glass, water, or polished metal.

Chemical compounds known as optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), absorb light in the ultraviolet and violet region of the electromagnetic spectrum (typically between 340 and 370 nm) and then fluoresce, reemitting light in the blue region of the spectrum (typically between 420 and 470 nm).

These additives have a "whitening" effect, which makes naturally yellow-orange materials appear less yellow or orange by making up for the lack of blue and purple light reflection by the substance's fluorophore's optical emission, which is blue and purple.

Therefore, we can conclude that it is true.

What is the mass of the molarity?

Molarity = Number of moles of solute/    volume of solution.

The mass percentage of the compound is given by % =

Mass of solute/ Mass of Solution x 100

According to the given equation,

The volume of the solution is 95.0 ml

The density of the solution is equal to the density of pure water that is 1g / mL.

Therefore the mass of solution is calculated by

Mass = Density x Volume

        =  1 g/ mL x 95.0 mL

        = 95.0 gm

If the main percentage is 0.92 % then,

Mass of solute

0.92 = Mass of solute / 95.00 gm x 100

One factor that influences the absorbance of a sample is the concentration (c). The expectation would be that, as the concentration goes up, more radiation is absorbed and the absorbance goes up. Therefore, the absorbance is directly proportional to the concentration.

What is beer lamberts law ?

The third factor is known as molar absorbance (ε), where concentrations are given in moles/liter and path lengths are given in centimeters. Some research areas talk more about extinction coefficients. When spectroscopy is used to measure the concentration of a sample, a specific wavelength of radiation is selected to irradiate the sample. As you probably know from other experience, certain chemical species absorb certain wavelengths of radiation and not others. Molar absorptivity is a measure of how much a species absorbs at a particular wavelength of radiation to which it is exposed. The process of absorbing electromagnetic radiation involves the excitation of species from ground states to higher energy excited states. This process is called an excited transition, and excited transitions have probabilities of occurrence. It is appropriate to talk about the allowed range of possible energy transitions within a chemical species. Some migrations are more legal or cheaper than others. Very favorable or very acceptable transitions have high molar absorptivity. Only slightly favorable or slightly tolerant transitions have low molar absorptivities. The higher the molar extinction coefficient, the higher the absorption. Therefore, molar absorbance is directly proportional to absorbance.

The molarity of the solution in the volumetric flask B is 0.0100 M.

This problem is solved firstly by using the concept of dilution formula which can be written as below:

M1V1 = M2V2

Given,

M1 = 1.25 M

V1 = 5 ml

V2 = 25 ml

By substituting all the values, we get

1.25 × 5 = M2 × 25 ml

M2 = 1.25 × 5 / 25

M2 = 0.25 M

Now,

Volume of solution pipet from volumetric flask A V2 = 2 ml

Molarity of solution in volumetric flask 'A' = 0.25 M = M2

Volume Volume of solution in volumetric flask B (V3) = 50 ml

Again by using dilution formula,

M2V2 = M3V3

By substituting all the values, we get

0.25 × 2 = M3 × 50 ml

M3 = 0.0100 M

Thus, we concluded that the molarity of the solution in the volumetric flask B is 0.0100 M.
