which method can be used to visualize lipids that have been separated by thin-layer chromatography by reversibly reacting with double bonds in fatty acids?

Explanation:

enzymes are biological catalysts that increase the rate of reaction without being used up in the reaction process.

this is done by providing an alternative route to the reaction progress that'll require a lower activation energy.

example - digestive enzyme Amylase, is used to breakdown sugars into glucose for cellular respiration.

the mole percent of oxygen be in the diving gas for the partial pressure of oxygen in the mixture to be 0.21 atm , the same as in air at 1 atm is 2.52%

Atm 8.32 is the total pressure.

0.21 atm is the partial pressure of oxygen gas.

The relationship between partial pressure, total pressure, and mole fraction is depicted here.

partial oxygen pressure Total pressure x Mole percent of oxygen -

Calculate the gas's mole fraction of oxygen.

0.21 atm 8.32 x Mole fraction

Mole fraction = 0.21/8.32 = 0.0252

As illustrated below, determine the mole percent of the gas. Mole percent is equal to the mole fraction divided by 100, which is 0.0252 times 100 and 2.52% respectively.

As a result, oxygen's mole percent is 2.52%.

The molarity of the K₂CO₃ solution is 2.36 M.

The unit of molarity is molar or M is the same as moles per liter, when n moles of a compound appear that have been dissolved in V liters of solution, the molarity formula is [tex]M = n/V[/tex]

M = molarity

n = number of moles

V = volume of solution

The concentration of the solution states the quantitative composition of the substance that has been dissolved and the solvent in the solution. Determination of the concentration or vice versa depends on the number of solution ratios of each substance that enters. Chemical reactions occur during the process and result from the presence of the same solution.

The equilibrium concentration of ICl is 17.97M

Equilibrium concentration is when both reactant and product are in concentration which does not change with time any more

Here given data is

Volume =  2.00L

Number of moles of ICl = 0.440 moles

Kc = 0.110

Balanced chemical equation

2ICl ⇄ I₂ + Cl₂

We have to calculate equilibrium concentration of icl = ?

Calculations for initial concentration

ICl =  0.440 moles/ 2.00L = 0.22M

I₂ = 0M

Cl₂ = 0M

Concentration of equilibrium

ICl = (0.22M - 2x)M

I₂ = xM

Cl₂ = xM

Calculation for Kc

Kc = 0.110 = [I₂][Cl₂]/[ICl]

0.110 = x²/ (0.22M-2x)²

0.332 = x(0.22M-2x)

x = 0.332×(0.22M-2x)

x = 0.0730 - 0.664x

0.664x = 0.0730

x = 0.664/0.0730

x = 9.095

The equilibrium concentration will

[I₂] = [Cl₂] = 9.095M

[ICl] =  0.22M - 2(9.095)

[ICl] = 17.97M

Equilibrium concentration of ICl is 17.97M

There is 12.4g of silver chromate.

Almost all alkali metal compounds and nitrates are soluble, but most silver compounds are not. Therefore, when the soluble salts silver nitrate and sodium chromate are mixed, insoluble silver chromate is formed and precipitated. This method involves titrating the chloride ion concentration in a solution with silver nitrate. A silver chloride precipitate forms when the silver nitrate solution is slowly added.

The endpoint of the titration is when all chloride ions have precipitated. Silver chromate precipitates as a brick-red precipitate from aqueous solutions. This reaction is also called a precipitation reaction. A precipitate is an insoluble solid that forms when solutions are mixed.

In phosphorous pentachloride, also known as pcl5, the central p atom's hybrid orbital, designated Sp3d, forms a sigma bond with an exterior cl atom. The P molecule hybridization is indicated by the symbol sp3d.

To create 5 P-Cl sigma bond in this situation, the P atom needs 5 orbitals. It needs to create the fifth sigma bond using one of its three 3d orbitals because it has three 3s and two 3p orbitals. These orbitals are combined to create five sp3d orbitals, making a triangular bipyramid.

The moles of solute per liter of solution is measured as molarity. For instance, when table salt is dissolved in water, water serves as both the solution and the solute. Sodium chloride weights 58.44 grams per mole. One liter of water and 58.44 grams of sodium chloride combine to form one molar solution, or 1M.

100 g of a solution Additionally, it is assumed that the starting density is 1.02 grandpa. We can therefore determine the volume or solution from this information. Volume of the solution is therefore equal to the solution's mass divided by its city. So we have 100 g of solutions here. Therefore, 100 g make up the majority of the solution.
