The melting points of stearic acid and linoleic acid can be attributed to differences in their molecular structures.

Stearic acid, also known as octadecanoic acid, is a saturated fatty acid with a straight carbon chain consisting of 18 carbon atoms. Each carbon atom in stearic acid is bonded to two hydrogen atoms and a carboxylic acid group (-COOH). The presence of saturated carbon-carbon (C-C) bonds throughout the molecule allows for strong intermolecular interactions, such as van der Waals forces, which require a relatively higher amount of energy to break. As a result, stearic acid has a higher melting point of 69 °C.

On the other hand, linoleic acid is an unsaturated fatty acid with 18 carbon atoms, but it contains two double bonds in its carbon chain. The presence of these double bonds introduces kinks in the molecule, preventing the carbon chain from packing closely together. This reduces the strength of intermolecular forces, resulting in a lower melting point. Linoleic acid has a melting point of approximately -5 °C.

In summary, the difference in the melting points of stearic acid and linoleic acid is primarily due to the presence of saturated versus unsaturated carbon-carbon bonds in their respective molecular structures.

To generate 50.0 g of sodium chloride according to the given chemical equation, we need 91.12 g of sodium chlorate.

To calculate the grams of sodium chlorate required to generate 50.0 g of sodium chloride, we first need to use the balanced chemical equation to determine the molar ratio of sodium chlorate to sodium chloride. From the equation 2NaClO3 → 2NaCl + 3O2, we can see that for every 2 moles of sodium chlorate, 2 moles of sodium chloride are produced.
The molar mass of sodium chloride is 58.44 g/mol, and so 50.0 g of sodium chloride corresponds to 50.0 g / 58.44 g/mol = 0.8557 moles.
Since the molar ratio of sodium chlorate to sodium chloride is 2:2, or simply 1:1, we know that we need 0.8557 moles of sodium chlorate to generate 50.0 g of sodium chloride.
The molar mass of sodium chlorate is 106.44 g/mol, and so to convert moles to grams, we can simply multiply the number of moles by the molar mass. Therefore, we need:
0.8557 moles x 106.44 g/mol = 91.12 g of sodium chlorate.
Therefore, to generate 50.0 g of sodium chloride according to the given chemical equation, we need 91.12 g of sodium chlorate.

Fraccion molar del soluto = 0.06

Fraccion molar del solvente = 0.94

Explanation:

Nuestra solución está compuesta por:

Soluto: 50 g de sal

Solvente: 250 mL de agua.

%m/m %m/v molalidad, molaridad, fracción molar del soluto y del solvente son distintas formas de definir la concentración:

% m/m son los gramos de soluto cada 100 g de solución.

No sabemos la masa de solución pero con la densidad del agua (solvente), sabemos que los 250 mL contienen 250 gramos de solvente. (Densidad del agua 1g/mL). En conclusión, la masa de solución es 50 g + 250g = 300

% m/m = (50g /300g ) . 100 = 16.6%

Vamos a definir que el volumen de la solución es igual al del solvente: 250 mL.

% m/v = la masa de soluto, cada 100 mL de solución

= (50 /250) . 100 = 20 %

Molalidad, son los moles de soluto por cada kg de solvente.

Convertimos gramos a kg → 250 g . 1kg /1000g = 0.25kg

Convertimos la masa de soluto (sal) a moles.

NaCl → 50 g . 1mol/ 58.45g = 0.855 moles

m = 0.855 /0.25 → 3.42 m (molalidad)

Molaridad son los moles de soluto por cada L de solución.

Convertimos mL a L → 250 mL . 1kg / 1000mL = 0.25 L

sabiendo que los moles de soluto son 0.855, en este caso la molaridad es igual a la molalidad ( 3.42 M)

Para calcular la fracción molar, necesitamos moles de soluto y de solvente.

Ya contamos con los moles de soluto.

Moles de solvente: 250 g . 1mol /18g = 13.89 mol

Moles totales = 0.855 + 13.89 = 14.745

Fracion molar del soluto: (0.855/ 14.745) = 0.06

Fraccion molar del solvente: (13.89 / 14.745) = 0.94

The mother liquor from the recrystallization of a dinitro compound is expected to contain other products, such as nitrites, nitrates, and aqueous solutions.

Explanation: In the mother liquor from the recrystallization of the dinitro compound, other products that are expected to be found are generally impurities or by-products that are not soluble in the recrystallization solvent, as well as a small amount of the product that did not crystallize.To remove the impurities that remain in the mother liquor, it is often essential to repeat the recrystallization procedure with a different solvent or a solvent mixture until the desired purity is achieved.In general, recrystallization is a technique that allows for the purification of a chemical substance by dissolving the impure substance in a solvent and then re-crystallizing it from a fresh solvent with appropriate cooling.A dinitro compound, as the name suggests, is a compound that contains two nitro groups. The recrystallization of such compounds often occurs as a result of their insolubility in some solvents at room temperature.

The mass of neon present in the given mixture is approximately 6.13 g.

Total volume of mixture = 1.00 L, Total pressure of mixture = 1.15 atm, Temperature of the mixture = 255 K, Partial pressure of helium = 0.75 atm. We are supposed to find the mass of neon present in the mixture. The mole fraction of helium can be calculated as X(He) = P(He) / P(total)X(He) = 0.75 / 1.15X(He) = 0.6522. Similarly, the mole fraction of neon can be calculated as X(Ne) = 1 - X(He)X(Ne) = 1 - 0.6522X(Ne) = 0.3478.

Now, let us calculate the number of moles of helium present in the mixture: n(He) = X(He) x V x P / RTn (He) = 0.6522 x 1.00 x 0.75 / 0.0821 x 255n(He) = 0.0224 mol. Similarly, the number of moles of neon can be calculated: n(Ne) = X(Ne) x V x P / RTn (Ne) = 0.3478 x 1.00 x 0.40 / 0.0821 x 255n(Ne) = 0.0119 mol. The mass of neon can be calculated by using the formula: mass = molar mass x number of moles mass = 20.2 g/mol x 0.0119 mol ≈ 6.13 g. Hence, the mass of neon present in the given mixture is approximately 6.13 g.

The balanced net reaction for the Sn (s) | SnCl2 (aq) || AlBr3 (aq) | Al (s) chemical cell is: 3Sn (s) + 2AlBr3 (aq) → 3SnBr2 (aq) + 2Al (s).

The given cell notation represents a redox reaction occurring in an electrochemical cell. The left half-cell consists of solid tin (Sn) in contact with an aqueous solution of tin(II) chloride (SnCl2). The right half-cell contains an aqueous solution of aluminum(III) bromide (AlBr3) and solid aluminum (Al).

To determine the balanced net reaction, we need to consider the transfer of electrons between the species involved. The oxidation half-reaction occurs at the anode, where tin (Sn) undergoes oxidation and loses electrons:

Sn (s) → Sn2+ (aq) + 2e-

The reduction half-reaction takes place at the cathode, where aluminum(III) bromide (AlBr3) is reduced and gains electrons:

2Al3+ (aq) + 6Br- (aq) → 2Al (s) + 3Br2 (aq) + 6e-

To balance the overall reaction, we need to multiply the oxidation half-reaction by 3 and the reduction half-reaction by 2 to ensure that the number of electrons transferred is equal:

3Sn (s) → 3Sn2+ (aq) + 6e-

4Al3+ (aq) + 12Br- (aq) → 4Al (s) + 6Br2 (aq) + 12e-

By adding the balanced half-reactions together, we obtain the balanced net reaction for the cell:

3Sn (s) + 2AlBr3 (aq) → 3SnBr2 (aq) + 2Al (s)

To determine the cell potential, additional information such as the standard reduction potentials of the species and the Nernst equation would be required. Without this information, it is not possible to calculate the cell potential accurately.

Answer:

C

Explanation:

Boyle's law states that "the volume of a given mass of gas is inversely proportional to its pressure at constant temperature."

Inverse proportionality means that as one quantity is increasing, the other quantity is decreasing and vice versa.

Hence, as the pressure was increased, the volume decreases accordingly in obedience to Boyle's law.

Answer:

What is TRUE about the missing volume is option C.

C. The volume will decrease due to inverse relationship of V & P

Explanation:

The given parameters of the gas are;

The initial pressure of the gas, P₁ = 2 atm

The initial volume of the gas, V₁ = 1.5 L

The final pressure of the gas, P₂ = 2 atm

Boyle's law states that, at constant temperature, the volume, 'V', of a given mass is inversely proportional to its pressure, 'P';

Mathematically, Boyle's law can be expressed as follows;

P ∝ 1/V

From which we have;

P·V = Constant

∴ P₁·V₁ = P₂·V₂

For the given gas, we get;

2 atm × 1.5 L = 6 atm × V₂

∴ V₂ = 2 atm × 1.5 L/(6 atm) = 0.5 L

Therefore, the volume decreases from 1.5 L to 0.5 L.

The anode reaction is: \(Cd(s) → Cd^2+(aq) + 2e^-\)

The cathode reaction is:\(2Br^-(aq) + Br2(l) + 2e^- → 2Br^-(aq)\)

The net cell reaction is: \(Cd(s) + Br2(l) → Cd^2+(aq) + 2Br^-(aq)\)

In a voltaic cell, the anode is where oxidation occurs, while the cathode is where reduction takes place. In this case, the anode consists of a \(Cd|Cd^2\)+ half cell, where the solid cadmium (Cd) electrode is oxidized to form cadmium ions \((Cd^2+)\) in the aqueous solution. The anode reaction is represented by the equation \(Cd(s) → Cd^2+(aq) + 2e^-\).

On the other hand, the cathode is a \(Br^-|Br2\) half cell. Here, bromide ions \((Br^-)\) from the aqueous solution are reduced, along with elemental bromine (Br2) to form additional bromide ions. The cathode reaction can be represented by the equation \(2Br^-(aq) + Br2(l) + 2e^- → 2Br^-(aq)\).

When we combine the anode and cathode reactions, we get the net cell reaction. The cadmium (Cd) from the anode reacts with the bromine (Br2) from the cathode to produce cadmium ions\((Cd^2+)\) and bromide ions (Br^-). The net cell reaction can be represented by the equation\(Cd(s) + Br2(l) → Cd^2+(aq) + 2Br^-(aq).\)

In the external circuit, electrons flow from the cadmium electrode (the anode) to the bromine electrode (the cathode), generating an electric current. The salt bridge, which connects the two half-cell compartments, allows the migration of ions to maintain charge balance. In this case, anions \((Br^-)\) migrate from the bromide half cell to the cadmium half cell through the salt bridge.
