Octanol is slightly soluble in water, and water is very soluble in octanol. why is it important to presaturate octanol with water and water with octanol when measuring ow?

Answers

Answer 1

N-Octanol and water are chosen because the connection between a substance's hydrophilicity and lipophilicity is measured by [tex]K_{OW}[/tex] (n-Octanol/Water partition coefficient). When a chemical is more dissolves in fat-like solvents like n-octanol, the value is more significant than one,  when it's more dissolved in water, the value is lower.

What is the partition coefficient?

The partition coefficient for the two-phase network comprising n-octanol and water is known as the [tex]K_{OW}[/tex] value. N-Octanol-Water Partition Ratio is another name for it.The connection between a substance's hydrophilicity (its ability to dissolve in water) and lipophilicity (its ability to dissolve in fat) is measured by [tex]K_{OW}[/tex]. The value is bigger if a drug is more accessible in fat-like liquids like n-octanol and less if a compound seems more water-soluble.Owing to linkage or fragmentation, substances that are involved in the octanol-water combination as multiple synthetic entities are each given a unique [tex]K_{OW}[/tex] ratio.

So, N-Octanol is chosen because it has a carbon/oxygen ratio that is comparable to that of lipids and because it shows both hydrophobic and hydrophilic properties. N-octanol, therefore, resembles the makeup and characteristics of cells and other living things.

A compound composed of 3. 3% h, 19. 3% c, and 77. 4% o has a molar mass of approximately 60 g/mol. What is the molecular formula of the compound?.

Answers

The molecular of the compound will be-(H₂CO₃)1= H₂CO₃

The given molecule has the molecular formula H2CO3, also known as Carbonic acid.

Given that-

Consequently,

H= 3.3%.

C=19.3%

O =77.4%

Number of H moles = 3.3/1 = 3.3

Number of C moles = 19.3/12 = 1.60

Number of O moles = 77.4/16 = 4.83

As a result, the ratio of C, H, and O atoms is 3.3: 1.60: 4.83.

Divide by the amount you obtain that is the smallest: 3.3/1.60; 1.60/1.60; 4.83/1.60 = 2: 1: 3

H2CO3 is the empirical formula.

Let (H2CO3)n be the molecular formula.

A molecular formula is a chemical formula that specifies how many atoms of each element there are in each molecule of a given substance.

Molar mass thus equals (21+112+3X16)n = 62n.

As per the inquiry, 62n = 60

alternatively, n= 0.96 (round figure is 1)

Therefore, carbonic acid is the chemical whose molecular formula is (H2CO3)1=H2CO3.

How many moles of iron metal are required to react completely with 12 moles of oxygen?

Answers

Answer:

16 moles

Explanation:

from the equation:

4Fe + 3O2 -----> Fe2O3

the mole ratio of Fe to O2 follows,

3 moles O2 reacts with 4 moles Fe.

therefore,

1 mole O2 reacts with 4/3 moles Fe

and 12 moles O2 reacts with (4/3) × 12 moles Fe = 16 moles

Answer:

9.0 moles of O2 and produce 6.0 moles of Fe2O3

Explanation:

Fe→Fe3++3e− iron. Is oxidised: it's losing electrons

O2+4e−→2O2− oxygen Is reduced, it's gaining electrons

Balance for the electrons.

The smallest common product of 3 and 4 Is 12.

4Fe→4Fe3++12e−

3O2+12e−→6O2−

Adding:

4Fe+3O2+12e−→4Fe3++12e−+6O2−

The electrons balance so they cancel out:

4Fe+3O2→4Fe3++6O2−

Since Fe and O can combine in a ratio of 2:3

Answers

Tetrahedral geometry is obtained when the central atom is bonded with four atoms.

When is the tetrahedral geometry obtained?

Tetrahedral literally means "having four faces" because the prefix tetra- specifies four and the suffix -hedral denotes a face of a solid. This shape develops when there are no lone electron pairs and four bonds are all on the same core atom. According to the VSEPR theory, the bond angles between the electron bonds are 109.5°.

Tetrahedral molecules include methane (CH4) as one example.

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.

Answers

If the change in entropy of the surroundings for a process at 451 k and constant pressure is -326 j/k, then heat flow absorbed (in kj) by the system is -147.026kJ.

What is entropy?

The entropy of particle is defined as how random it move. It shows the randomness of the system or may be disorders of the system. It is used to measure the unavailable energy for performing useful work.

Unit of entropy = J/K

Formula:

∆s = ∆Q/T

where,

∆s = change in entropy of the surrounding = -326J/K

∆Q = heat absorbed from surrounding

T = Temperature = 451K

∆Q = ∆s × T

∆Q = -326 × 451

∆Q = 147,026 J

∆Q = 147.026 kJ

The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene. This is significant because a cell reads the genetic code for proteins in groups of three nucleotides. These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein.

Given,

the mass of Na is 23 g

However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity. It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts. The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water. A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.

Mass of CCl2F2= number of moles of CF2Cl2 × molar mass of CF2Cl2= 0.2139× 120.91

Mass of CF2Cl2 (Theoretical yield) = (12.5/25.8626) × 100

Percentage yield= 48.33%

Thus, we concluded that the percentage yield of CF2Cl2 is 48.33%.

The hydrolysis of phosphatidylinositol 4,5‑bisphosphate (pip2) by phospholipase c generates which two secondary messengers?

Answers

The hydrolysis of phosphatidylinositol 4,5‑bisphosphate (pip2) by phospholipase C generates inositol 1,4,5-trisphosphate ( [tex]IP_{3}[/tex] ) and diacylglycerol (DAG) secondary messengers.

The small molecules and ions relay signals received by cell-surface receptors to effector protein is referred as second messenger.Examples of secondary messengers are cyclic AMP,cyclic GMP inositol 1,4,5-trisphosphate ( [tex]IP_{3}[/tex] ) ,diacylglycerol (DAG) ,and calcium. [tex]IP_{3}[/tex] induces a transient increase in intracellular free [tex]Ca^{+2}[/tex] ,whereas DAG directly activates protein kinase C.

There are two distinct kinds of signaling pathways that use phosphatidylinositol. Phospholipase C breaks down phosphatidylinositol-4,5-bisphosphate to create IP3, which serves as a crucial part of the Ca-signaling mechanism described earlier.

When a nonmetal bonds with a nonmetal: When a nonmetal bonds with a nonmetal: a molecular compound forms. a covalent bond is involved. electrons are shared. all of the above are true none of the above

Answers

When a nonmetal bonds with a nonmetal, a covalent bond is involved. Details about non-metals can be found below.

What is a nonmetal?

A nonmetal is an element, such as phosphorus or chlorine, that does not have the chemical or physical properties of a metal.

A metal is known to lose or donate electrons when it goes into a reaction, hence, an electrovalent bond is usually formed.

However, a nonmetal is known to accept or gain electrons when it goes into reactions. This means that when two nonmetals bonds in a chemical reaction, a covalent bond is formed between them.

Covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.
