Which fat-formation pathway is the most efficient and direct?.

Answer:

The average speed is = 11.1m/s

Explanation:

Recall that average speed is defined as the total distance traveled with respect to the total number of time, therefore we say that the total distance traveled is 40Km according to your question, remember, the unit of speed is metre per second, so you change 40km by multiplying it with 1000, recall that, 1000m = 1km, so 40km×1000m = 40,000m, also 1h= 60×60, =3600s

Remember the formula for average speed is = Total distance traveled÷ total time taken

Thus; 40000m/3600s

Then we had, 11.1m/s...

Explanation:

The mass of N₂ in the equilibrium mixture can be determined through the mole concept and the application of the ideal gas law. Since the equilibrium mixture contains both N₂ and O₂ gases, the equation that will be used to determine their masses is as follows:

2N₂(g) + O₂(g) ⇌ 2NO(g)

The balanced equation shows that two moles of N₂ react with one mole of O₂ to produce two moles of NO. This means that the initial number of moles of N₂ in the mixture will be twice the number of moles of NO. The mass of N₂ can be calculated using the ideal gas law, which is PV = nRT.

The given conditions can be used to calculate the partial pressure of N₂, which can then be used to determine the number of moles of N₂ in the mixture and the corresponding mass of N₂.

To calculate the partial pressure of N₂, the mole fraction of N₂ must first be determined. This can be done using the equation:

X(N₂) = n(N₂) / n(total)

where X(N₂) is the mole fraction of N₂, n(N₂) is the number of moles of N₂, and n(total) is the total number of moles of gas in the mixture. Since there are no other gases in the mixture, the mole fraction of N₂ will be equal to the number of moles of N₂ divided by the total number of moles of gas.

Using the ideal gas law, the partial pressure of N₂ can then be calculated:

P(N₂) = X(N₂) * P(total)

where P(N₂) is the partial pressure of N₂, X(N₂) is the mole fraction of N₂, and P(total) is the total pressure of the mixture. The total pressure can be calculated using Dalton's law of partial pressures, which states that the total pressure is equal to the sum of the partial pressures of all the gases in the mixture. Once the partial pressure of N₂ has been determined, the number of moles of N₂ in the mixture can be calculated using the ideal gas law:PV = nRTwhere P is the partial pressure of N₂, V is the volume of the mixture, n is the number of moles of N₂, R is the gas constant, and T is the temperature in Kelvin. Rearranging this equation to solve for n, we get:

n = PV / RT

Finally, the mass of N₂ in the mixture can be calculated using the molar mass of N₂ and the number of moles of N₂:

mass(N₂) = n(N₂) * M(N₂)

where M(N₂) is the molar mass of N₂.

The mass of N₂ in the equilibrium mixture can be determined using the ideal gas law and the mole concept. The partial pressure of N₂ can be calculated using the mole fraction of N₂ and the total pressure of the mixture. The number of moles of N₂ can then be calculated using the partial pressure, volume, temperature, and gas constant. Finally, the mass of N₂ can be calculated using the number of moles and the molar mass of N₂.

The third problem would be the same steps as the second one.

The fourth problem would be (0.460M)(5.50L)= 2.53 moles

The molarity of a solution which contains 0.256 mol of a substance dissolved in 143 mL of solution is 1.79.

Molarity of a given solution is known as the total number of moles of solute per litre of the solution.  A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

The unit of molarity is mol L⁻¹.

Molarity is temperature dependent because as temperature changes, volume of the solution also changes.

Given,

No. of moles = 0.256

Volume of solution = 143ml

Molarity = (0.256 ÷ 0.143) = 1.79

To assess whether each function represents the number of steps after m minutes, we need to consider the characteristics of step tracking. Here are a few key points to consider:

Steps are cumulative: The total number of steps increases over time. The function should reflect this cumulative nature.

Linear relationship: Assuming a constant walking pace, the number of steps should have a linear relationship with time. If the number of steps consistently increases by the same amount for each minute, the function will likely be linear.

Non-negative values: The number of steps cannot be negative. The function should output non-negative values for all valid input values.

Based on these considerations, let's evaluate the proposed functions:

Student 1: s(m) = m^2

Explanation: The function s(m) = m^2 represents a quadratic relationship, not a linear one. In this case, the number of steps would increase quadratically with time, which is not realistic for step tracking. Therefore, this function does not accurately represent the number of steps after m minutes.

Student 2: s(m) = 5m + 10

Explanation: The function s(m) = 5m + 10 represents a linear relationship. It accounts for a constant increase in the number of steps (5 steps per minute) along with an initial offset of 10 steps. This function aligns with the characteristics of step tracking, making it a reasonable representation of the number of steps after m minutes.

In summary, Student 2's function, s(m) = 5m + 10, is more likely to accurately represent the number of steps after m minutes, as it reflects the cumulative, linear relationship between time and step count.

The mass of camphor (C10H16O) that contains a million hydrogen atoms is approximately 15.068 g.

To calculate the mass of camphor (C10H16O) that contains a million (1,000,000) hydrogen atoms, we need to determine the molar mass of camphor and then use it to calculate the mass.

The molar mass of camphor (C10H16O) can be calculated by summing the atomic masses of its constituent atoms:

- Carbon (C) has a molar mass of 12.01 g/mol.

- Hydrogen (H) has a molar mass of 1.008 g/mol.

- Oxygen (O) has a molar mass of 16.00 g/mol.

So, the molar mass of camphor is:

(10 * 12.01 g/mol) + (16 * 1.008 g/mol) + (1 * 16.00 g/mol) = 152.23 g/mol.

Now, to calculate the mass of camphor containing a million hydrogen atoms, we need to determine the ratio of hydrogen atoms to camphor molecules.

From the molecular formula of camphor, we see that there are 16 hydrogen atoms per camphor molecule (C10H16O).

Therefore, the mass of camphor containing a million hydrogen atoms is calculated as follows:

Mass = (1,000,000 hydrogen atoms / 16 hydrogen atoms per camphor molecule) * (1 camphor molecule / 6.022 × 10²³ camphor molecules per mole) * (152.23 g/mol)

        = (1,000,000 / 16) * (1 / 6.022 × 10²³) * 152.23 g

Mass     ≈ 15.068 g (rounded to 4 significant digits)

The question is incomplete, the complete question is;

Consider a pure crystalline solid that is heated from absolute zero to a temperature above the boiling point of the liquid. Which of the following processes produces the greatest increase in the entropy of the substance? A ) melting the solid B ) heating the gas C ) vaporizing the liquid D ) heating the solid E ) heating the liquid

Answer:

vaporizing the liquid

Explanation:

We generally define entropy in chemistry as the degree of disorderliness in a system. The entropy of gases is greater than that of liquids and the entropy of liquids is greater than that of solids. It then logically follows that the degree of entropy in gases is the greatest among all the states of matter while the entropy of solids is the least among all the states of matter since solid particles remain in their mean positions and can only vibrate or sometimes rotate. Liquid particles may translate while gaseous particles move at high velocity with negligible intermolecular forces of attraction between them.

A phase transition from liquid to gaseous state now represents the greatest change in the entropy of the system since gases posses the highest entropy among all the states of matter, hence the answer.

Answer:

P = 2.145kPa

Explanation:

R = 8.314J/mol.K

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles if the gas

R = ideal gas constant

T = temperature of the gas

n = number of moles

n = mass / molar mass

n = 22.1 / 44 = 0.50moles
