Answer:

the final mole of the flexible container = 12.92 moles

Explanation:

Given that :

initial volume of a flexible container = 6.13 L

initial mole of a flexible container = 6.51 mol

final volume of a flexible container = 18.3 L

final mole of a flexible container = ???

Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Therefore,

\(n= \dfrac{V_2*n_1}{V_1}\)

\(n= \dfrac{18.3*6.51}{6.13}\)

n = 19.43

\(n=n_1+n_2\)

19.43 = 6.51 + n₂

n₂ = 19.43 - 6.51

n₂ = 12.92 moles

Thus; the final mole of the flexible container = 12.92 moles

F2 has a higher heat capacity due to its more intricate electrical structure and increased number of vibrational modes.

The amount of heat needed to raise the temperature of one mole of a substance by one degree Celsius at constant volume is known as the molar constant volume heat capacity (Cv). The atomic and molecular characteristics of the substance, such as its mass, structure, and vibrational modes, determine the value of Cv.

The energy needed to dissociate a bond between two atoms in a molecule is known as the bond dissociation energy (BDE). The link between two fluorine atoms can be broken with less energy because F2 has a lower bond dissociation energy than O2 and N2.

Rounding to three significant figures, the binding energy per atom of 129Te is 0.115 MeV.

To calculate the binding energy per atom, we need to first determine the mass defect, which is the difference between the actual mass of the atom and the sum of the masses of its individual protons, neutrons, and electrons.

The number of protons in an atom of 129Te is 52 since the atomic number of tellurium is 52. Therefore, the number of neutrons is 77 (129 - 52).

The mass of 52 protons is 52 x 1.007825 amu = 52.4161 amu

The mass of 77 neutrons is 77 x 1.008665 amu = 77.7292 amu

The mass of the electrons can be ignored as they contribute very little to the overall mass of the atom.

The total mass of the individual particles is:

52.4161 amu + 77.7292 amu = 130.1453 amu

The actual mass of the atom is given as 128.906594 amu, so the mass defect is:

130.1453 amu - 128.906594 amu = 1.2387 amu

The binding energy per atom can be calculated using Einstein's famous equation \(E = mc^2\), where c is the speed of light. We will convert the mass defect from amu to kilograms and the speed of light from meters per second to centimeters per second, so the units will work out correctly in the end.

\(1 amu = 1.66054 * 10^{-27} kg\)

Speed of light,\(c = 2.99792 * 10^{10} cm/s\)

The mass defect in kilograms is:

\(1.2387 amu * 1.66054 * 10^{-27} kg/amu = 2.055 * 10^{-25} kg\)

The binding energy in joules per atom is:

\(E = (2.055 * 10^{-25} kg) * (2.99792 * 10^{10} cm/s)^2 = 1.849 * 10^{-8} J\)

Finally, we convert the binding energy from joules to MeV:

\(1 MeV = 1.60218 * 10^{-13} J\)

Therefore, the binding energy per atom in MeV is:

\((1.849 * 10^{-8} J) / (1.60218 * 10^{-13} J/MeV) = 0.115 MeV\)

Rounding to three significant figures, the binding energy per atom of 129Te is 0.115 MeV.

The changes in hybridization of the B atom which is a result of the given reaction is C. Before the reaction, boron is sp2 hybridized, and after the reaction it is sp3 hybridized.

Hybridization refers to the process of mixing the orbitals of an atom to produce new orbitals of equivalent energy. It allows for the formation of covalent bonds by changing the shapes of atomic orbitals to maximize the overlap of bonding orbitals with other atoms.

The hybridization state of an atom is determined by the type of orbital that overlaps with other atoms to form covalent bonds. The orbital hybridization of an atom is determined by its electron domain geometry, or the number of electron pairs it shares in its bonds.

The reaction of BF₃ and NH₃ to produce F₃B―NH₃ does change the hybridization of the boron (B) atom from sp2 hybridization to sp3 hybridization. Therefore, before the reaction boron is sp2 hybridized, and after the reaction, it is sp3 hybridized. Hence, the correct answer is Option C.

the bond order for Li2 is 1, and the bond order for Li2- is -0.5.To calculate the bond order for Li2 and Li2-, we need to construct their molecular orbital (MO) diagrams.

For Li2, each Li atom contributes one valence electron. In the MO diagram, we have two Li 1s orbitals that combine to form two molecular orbitals: one bonding (σ) and one antibonding (σ*). Since there are two electrons in the bonding molecular orbital and no electrons in the antibonding molecular orbital, the bond order for Li2 is (2-0)/2 = 1.

For Li2-, we have an additional electron, resulting in a total of three valence electrons. In the MO diagram, one electron occupies the bonding molecular orbital (σ) and the other two occupy the antibonding molecular orbital (σ*). Therefore, the bond order for Li2- is (1-2)/2 = -0.5.

So, the bond order for Li2 is 1, and the bond order for Li2- is -0.5.

The treatment of an alkene with Br2 and water adds the substituents Br across the double bond to form a halohydrin. This reaction is known as halogenation.

The Br2 molecule is first polarized by the double bond of the alkene, causing the bromine molecule to break apart and form a bromonium ion. The bromonium ion then reacts with water, which acts as a nucleophile, attacking the positive charge of the bromonium ion and displacing one of the bromine atoms. This results in the addition of a bromine atom and a hydroxyl group (OH) across the double bond, forming a halohydrin. In conclusion, the treatment of an alkene with Br2 and water leads to the formation of a halohydrin, with a bromine atom and a hydroxyl group added across the double bond.

Factors affecting the number of energy storage molecules producers make include light intensity, carbon dioxide concentration, temperature, and water availability, which all influence the rate of photosynthesis.

Photosynthesis is the process by which producers (mainly plants) create energy storage molecules, such as glucose, using light energy, water, and carbon dioxide. Four primary factors affect the rate of photosynthesis and, therefore, the production of energy storage molecules:
1. Light intensity: As light intensity increases, photosynthesis rate increases, leading to more energy storage molecules being produced, up to a certain point.
2. Carbon dioxide concentration: Higher CO2 levels result in increased photosynthesis rates, providing more building blocks for energy storage molecules.
3. Temperature: Photosynthesis is temperature-dependent, with optimal rates occurring within a specific range for each plant species.
4. Water availability: Sufficient water is necessary for photosynthesis to occur, as it is a crucial reactant in the process.

These factors work together to determine the number of energy storage molecules a producer can make.

According to Steno’s laws of Stratigraphy, the layers of rocks that are older according to the questions are A (Law of Cross-cutting relationships), D (Law of Cross-cutting relationships), D (Law of Original horizontality), J (Law of Superposition).

Geology and the Earth sciences have a discipline known as stratigraphy that focuses on layering (stratification) and rock layers (strata). It is mostly used towards the study of layered volcanic rocks and sedimentary rocks.

Stratigraphy examines the origin, makeup, and spread of these rock layers in addition to their organization and succession. Therefore, evaluating Time and Space is essential for the investigation of archaeological and natural stratification.

The patterns of rock layer deposition are described by Steno's laws of stratigraphy. Laws of superposition, original horizontality, cross-cutting relationships, and lateral continuity are the four laws.

The oldest layer in a succession of sedimentary rock layers is at the bottom, and the layers get younger as they move up the sequence, according to the law of superposition, a key stratigraphic concept.

According to the Law of Original Horizontality, all rock strata were initially deposited horizontally and are therefore susceptible to deformation. This enables us to deduce that for the rocks to be slanted, something must have occurred to them. This comprises quakes, faulting, and mountain-building activities.

According to the Law of Crosscutting Relationships, any faults or other rock bodies that cut through other rocks must be younger in age than the rocks they cut and displace.

According to the Law of Lateral Continuity, all rock strata are laterally continuous but subject to disruption or displacement due to subsequent events. When a stream or river erodes a section of the rock strata, this can occur.

The current industrial preparation of adipic acid primarily involves the oxidation of cyclohexane with a mixture of nitric acid and air. The major by-product of this process is nitrous oxide (N₂O), which is an atmospheric pollutant.

Nitrous oxide is a potent greenhouse gas and contributes to global warming. It has a long atmospheric lifetime, estimated to be around 120 years, and is responsible for approximately 6% of the total greenhouse effect. Nitrous oxide also plays a role in the depletion of the ozone layer. It is a precursor to nitrogen oxides, which can react with ozone to destroy it. Nitrous oxide is also a major contributor to acid rain, as it can react with water vapor in the atmosphere to produce nitric acid.

In the industrial preparation of adipic acid, cyclohexane undergoes two main steps: oxidation and cleavage. First, cyclohexane is oxidized to cyclohexanol and cyclohexanone in the presence of a mixture of nitric acid and air. This reaction produces nitrogen oxides (NOx) as side products. In the next step, cyclohexanol and cyclohexanone are further oxidized to adipic acid using more nitric acid. This process releases nitrous oxide (N₂O) as the major by-product.

In conclusion, the industrial preparation of adipic acid involves the production of nitrous oxide and other nitrogen oxides as by-products. Nitrous oxide is a potent greenhouse gas and atmospheric pollutant, contributing to global warming, ozone depletion, and acid rain. Efforts are being made to reduce emissions of nitrous oxide from industrial processes through the use of more efficient technologies and processes.
