The partial pressure of krypton is 415.6 mmHg and the partial pressure of carbon dioxide is 382.4 mmHg.

To find the partial pressure of each gas in the mixture, we need to use the mole fraction of each gas.

First, we need to find the moles of each gas in the mixture:

moles of Kr = 14.2 g / 83.8 g/mol = 0.1699 mol
moles of CO2 = 6.92 g / 44.01 g/mol = 0.157 mol

Next, we need to find the total moles in the mixture:

total moles = moles of Kr + moles of CO2 = 0.1699 mol + 0.157 mol = 0.3269 mol

Now we can find the mole fraction of each gas:

mole fraction of Kr = moles of Kr / total moles = 0.1699 mol / 0.3269 mol = 0.5198
mole fraction of CO2 = moles of CO2 / total moles = 0.157 mol / 0.3269 mol = 0.4802

Finally, we can use the mole fractions to calculate the partial pressure of each gas:

partial pressure of Kr = mole fraction of Kr x total pressure = 0.5198 x 798 mmHg = 415.6 mmHg

partial pressure of CO2 = mole fraction of CO2 x total pressure = 0.4802 x 798 mmHg = 382.4 mmHg

Therefore, the partial pressure of krypton is 415.6 mmHg and the partial pressure of carbon dioxide is 382.4 mmHg.

Isomers are compounds that have the same molecular formula but different arranged differently of the atoms.

For example

So even if they have the same proportion of their atoms, the chemical identity is different

The answer is option B: no because more than one compound can have the same ratio of masses of elements if the atoms are arranged differently.

Answer:

The balanced chemical equation is:

- Ratio of Al2O3 to O2: 2:3R

- Ratio of Al2O3 to Al: 2:4R

- Ratio of Al to O2: 4:3R

Explanation:

To balance the chemical equation, it is necessary to have the same amount of elements on the reactant side as on the product side:

Now we know that the reaction is balanced, because on the reactant side and on the products side there are:

- 4 Al

- 6 O

Now that the equation is balanced, we can write the ratios with the stoichiometry of the reaction.

Biomass combustion is referred to as a process in which organic materials are burnt and their remains are used to produce energy.

The process of combustion is very simple it refers to the burning of biomass which include wood, farm waste, and crops which are further used to produce or generate energy in the form of electricity and also heat, it can be termed as renewable energy that utilized the energy of biomass to produce another form of energy.

The Grate furnace method is one of the common methods used for biomass combustion and comprises several steps for the recovery of energy.    

The first step consists of drying up the biomass by removing all the moisture using heat. The next step includes the production of flames and heat by combusting hydrogen present in it. After that, the remaining solid waste will undergo combustion in the presence of oxygen.

The last step includes the disposal of ash which gets accumulated due to incombustible materials like sand.

The camel consumed approximately 2.24 kg of protein from the Bermudagrass hay.

To calculate the amount of protein the camel consumed, we need to consider the dry matter basis of the hay. Here's how you can calculate it:

Calculate the dry matter weight of the hay:

Dry Matter Weight = Total Weight of Hay × Dry Matter Percentage

Dry Matter Weight = 18.3 kg × (83.4/100)

Dry Matter Weight = 18.3 kg × 0.834

Dry Matter Weight = 15.2442 kg

Calculate the protein content in the dry matter;

Protein Content = Dry Matter Weight × Protein Percentage

Protein Content = 15.2442 kg × (14.7/100)

Protein Content = 15.2442 kg × 0.147

Protein Content = 2.2414194 kg

Therefore, the camel consumed approximately 2.24 kg of protein from the Bermudagrass hay.

Answer:

It's the first or the second answer.

Explanation:

The solution to the equation and value of variable 21(3d - 4) + 100 = 58 is d = 2/3.

Solve the equation 21(3d - 4) + 100 = 58, we can begin by simplifying and isolating the variable:

21(3d - 4) + 100 = 58

Distribute 21 to the terms inside the parentheses:

63d - 84 + 100 = 58

Combine like terms:

63d + 16 = 58

Subtract 16 from both sides:

63d = 42

Divide both sides by 63:

d = 42/63

Simplifying the fraction gives:

d = 2/3

The solution to the equation is d = 2/3.

The solution to the equation 21(3d - 4) + 100 = 58 is d = 2/3. By simplifying the equation, we find that dividing both sides by 63 results in the solution of d = 2/3, which satisfies the original equation.

Answer:

2p is the correct representation

Explanation:

The magnitude change of H ion concentration in the second solution compared to the first is 1000-fold (10³).

The pH scale measures the acidity or basicity of a solution based on the concentration of H+ ions present. It is a logarithmic scale, which means that each change of one pH unit corresponds to a tenfold change in H⁺ concentration.

Therefore, the difference of three pH units between the two solutions corresponds to a 10³ or 1000-fold difference in H⁺ ion concentration. This means that the second solution with a pH of 2 is much more acidic than the first solution with a pH of 5, and its H⁺ ion concentration is 1000 times higher.

In general, the pH scale provides a convenient way to compare the relative acidity or basicity of different solutions, and it has many important applications in chemistry, biology, and other fields.

The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

The solvents that would likely lead to major success in nitration of benzoic acid are toluene and nitrobenzene.

Benzoic acid can be nitrated under favorable conditions using toluene, which is frequently employed as a solvent in nitration operations. Being a nitro-substituted benzene compound, nitrobenzene can also work well as a solvent for nitrating benzoic acid.

In nitration reactions, bromobenzene and o-xylene are not frequently employed as solvents, and benzaldehyde is not a good choice either.

Eight tetrahedral sites are labeled with Fe³⁺ ions and four octahedral sites are labeled with Co²⁺ ions.

To represent the inverse spinel structure of CoFe₂O₄ in a unit cell, we need to label the ions based on their positions in the crystal structure.

In the inverse spinel structure, one-half of the octahedral sites are occupied by divalent metal ions, while one-half of the tetrahedral sites and the remaining octahedral sites are occupied by trivalent metal ions. The chemical formula of CoFe₂O₄ suggests that the cobalt (Co) ions occupy one-half of the octahedral sites, while the iron (Fe) ions occupy both the tetrahedral and the remaining half of the octahedral sites.

Therefore, we can label the ions in the unit cell of CoFe₂O₄ as follows:

Eight tetrahedral sites are labeled with Fe³⁺ ions.

Four octahedral sites are labeled with Co²⁺ ions.

Four octahedral sites are labeled with Fe³⁺ ions.

The unit cell of CoFe₂O₄ can be represented by the following diagram, where the small spheres represent Co²⁺ ions, and the large spheres represent Fe³⁺ ions:

Note that this is a simplified representation of the unit cell, as it only shows one layer of ions. In reality, the structure of CoFe₂O₄ is three-dimensional, and the unit cell contains many more ions.
