COFC and TOFC are both terms used in the freight forwarding industry, but they refer to different types of transportation methods.The main difference between COFC and TOFC lies in the type of cargo being transported. COFC involves loading containers onto flat railcars, while TOFC involves loading entire trailers.  

Here is a detailed explanation of the difference between COFC and TOFC:

1. Definition:
- COFC: COFC stands for Container on Flat Car. It refers to a transportation method where containers are loaded directly onto flat railcars. These containers are typically standardized and can be easily transferred between different modes of transportation, such as trucks, ships, and trains.
- TOFC: TOFC stands for Trailer on Flat Car. It involves loading entire trailers onto flat railcars. Unlike COFC, where only the containers are transferred, TOFC includes the entire trailer, including the cargo inside it.

2. Loading Process:
- COFC: In COFC, containers are typically loaded onto flat railcars using cranes or other lifting equipment. The containers are securely placed on the flatcar and can be easily secured to prevent movement during transportation.
- TOFC: In TOFC, trailers are loaded onto flat railcars using ramps or other loading equipment. The trailers are driven onto the flatcar and securely attached to prevent movement.

3. Benefits and Limitations:
- COFC: COFC offers several benefits, including efficient intermodal transportation, reduced handling of cargo, and increased security of cargo. However, it has a limitation that it requires specialized containers to be used.
- TOFC: TOFC also offers efficient intermodal transportation and reduced cargo handling. However, it provides the advantage of being able to transport a wider range of cargo, including oversized or irregularly shaped items. One limitation is that it requires specialized flat railcars to accommodate the trailers.

In conclusion, the main difference between COFC and TOFC lies in the type of cargo being transported. COFC involves loading containers onto flat railcars, while TOFC involves loading entire trailers. Both methods offer efficient intermodal transportation, but COFC requires specialized containers, while TOFC can accommodate a wider range of cargo.

Explanation:

When a metal is heated the kinetic energy in the particles increases and hence the force of attraction decreases amongst the particles - as electrons try to escape due to kinetic energy. This causes the metal to expand.

The R value for air under STP, based on density and the average molar mass, is approximately 287.058 J/kg·K.

To calculate the R value based on the density and average molar mass of air under Standard Temperature and Pressure (STP).
First, let's establish the necessary information. At STP, the temperature is 273.15 K and the pressure is 1 atm (101.325 kPa). The average molar mass of air is approximately 28.97 g/mol. To calculate density at STP, we'll use the equation:
Density (ρ) = (P × M) / (R × T)
where P is pressure, M is molar mass, R is the gas constant, and T is temperature. We want to find R, so let's rearrange the equation:
R = (P × M) / (ρ × T)
Next, we need to find the density of air under STP. We can use the Ideal Gas Law:
PV = nRT
where V is volume and n is the number of moles. The density (ρ) can be expressed as:
ρ = m/V = (n × M) / V
Combining the two equations and solving for ρ, we get:
ρ = (P × M) / (R × T)
We have P, M, and T, so we can calculate ρ:
ρ = (101.325 kPa × 28.97 g/mol) / (8.314 J/mol·K × 273.15 K) ≈ 1.225 kg/m³
Now we can calculate R using the equation we derived earlier:
R = (101.325 kPa × 28.97 g/mol) / (1.225 kg/m³ × 273.15 K) ≈ 287.058 J/kg·K

When the temperature is decreased to 150 K while keeping the pressure constant at 1.5 atm, the new volume would be 1.15 L. The volume decreases from the initial volume of 2.3 L to the new volume of 1.15 L.

According to the ideal gas law, the relationship between pressure (P), volume (V), and temperature (T) of a gas is given by;

PV = nRT

Where; P = pressure (in atm)

V = volume (in liters)

n = number of moles of gas

R = ideal gas constant (0.0821 L·atm/(mol·K))

T = temperature (in Kelvin)

In this case, the pressure is constant at 1.5 atm. The initial temperature is 300 K, and the initial volume is 2.3 L. The chemist then decreases the temperature to 150 K while keeping the pressure constant.

To determine the new volume, we can use the combined gas law, which relates the initial and final conditions of pressure, volume, and temperature;

(P₁ × V₁) / T₁ = (P₂ × V₂) / T₂

Substituting the given values;

(1.5 atm × 2.3 L) / 300 K = (1.5 atm × V₂) / 150 K

Simplifying the equation;

(1.5 × 2.3) / 300 = 1.5 × V₂ / 150

0.0115 = 1.5 × V₂ / 150

V₂ = (0.0115 × 150) / 1.5

V₂ = 1.15 L

Therefore, the new volume would be 1.15 L.

Explanation:

The answer is C) 0.5 kg. This is because Plutonium-238 has a half-life of 87.7 years, which means that after 87.7 years, half of the original amount of Plutonium-238 will remain. In this case, that would be 2 kg * 0.5 = 0.5 kg.

Plutonium-238 is a radioactive element used as a power source in spacecraft like Voyager and New Horizons. It has a half-life of 87.7 years. Suppose we have 2 kg of plutonium-238 right now. Radioactive decay is a random event. So, it is impossible to predict when a specific atom will decay. But we can find how much radioactive material is remaining after a specific period of time.

The half-life of a radioactive material is the time required for half of the radioactive material to decay. The formula to calculate the remaining material is:

N(t) = N0 × (1/2)^(t/t1/2)

Where N(t) is the remaining material at time t, N0 is the initial material, t1/2 is the half-life, and t is the elapsed time.

The initial material is 2 kg, half-life is 87.7 years, and the elapsed time is also 87.7 years.

N(87.7) = 2 kg × (1/2)^(87.7/87.7)= 1 kg × 0.5= 0.5 kg

Therefore, the amount of plutonium remaining after 87.7 years will be 0.5 kg. So, the answer is option C.

Explanation:

The following data were obtained from the question:

Mass of compound = 0.144 g

Mass of CO2 = 0.352 g

Mass of H2O = 0.0480 g

Empirical formula of compound =?

Next, we shall determine the mass of carbon (C), hydrogen (H) and oxygen (O) present in the compound. This can be obtained as follow:

For carbon (C):

Molar mass of CO2 = 12 + (2×16)

Molar mass of CO2 = 44 g/mol

Mass of CO2 = 0.352 g

Mass of C in the compound

= 12/44 × 0.352

= 0.096 g

For Hydrogen (H):

Molar mass of H2O = (2×1) + 16

Molar mass of H2O = 18 g/mol

Mass of H2O = 0.0480 g

Mass of H in the compound

= 2/18 × 0.0480

= 0.0053 g

For oxygen (O):

Mass of O = mass of compound – (mass of C + mass of H)

Mass of compound = 0.144 g

Mass of C = 0.096 g

Mass of H = 0.0053 g

Mass of O = 0.144 – (0.096 + 0.0053)

Mass of O = 0.144 – 0.1013

Mass of O = 0.0427 g

Finally, we shall determine the empirical formula of the compound as follow:

C = 0.096 g

H = 0.0053 g

O = 0.0427 g

Divide both side by their molar mass

C = 0.096 / 12 = 0.008

H = 0.0053 / 1 = 0.0053

O = 0.0427 / 16 = 0.0027

Divide by the smallest

C = 0.008 / 0.0027 = 3

H = 0.0053 / 0.0027 = 2

O = 0.0027 / 0.0027 = 1

Therefore, the empirical formula of the compound is C3H2O1

The energy associated with the annihilation of a positron and an electron is approximately 2.7416 × 10⁻⁸ kilojoules per mole.

When a positron and an electron annihilate each other, their combined mass is completely converted into energy according to Einstein's mass-energy equivalence principle (E=mc²). To calculate the energy associated with this process in kilojoules per mole (kJ/mol), we need to determine the mass of the positron-electron pair and then apply the appropriate conversion factors.

The mass of an electron is approximately 9.10938356 × 10⁻³¹ kilograms, and since the positron has the same mass, the combined mass of the pair is twice that value. To convert this mass to moles, we need to divide it by Avogadro's number, which is 6.022 × 10²³ particles/mol.

Now, to calculate the energy associated with the annihilation process, we can use the equation E=mc². The mass of the positron-electron pair is multiplied by the square of the speed of light, c, which is approximately 2.998 × 10⁸ meters per second.

Therefore, the energy associated with the annihilation of a positron and an electron can be calculated as follows:

Energy (E) = (2 * mass of electron) * (speed of light)²

Substituting the known values and performing the calculation, we find:

E = (2 * 9.10938356 × 10⁻³¹ kg) * (2.998 × 10⁸ m/s)²

Finally, convert the energy to kilojoules per mole by dividing by Avogadro's number:

Energy (E) = [(2 * 9.10938356 × 10⁻³¹ kg) * (2.998 × 10⁸ m/s)²] / (6.022 × 10²³ particles/mol)

= 2.7416 × 10⁻³⁶ kg m²/s²/particles * mol

To convert this energy to kilojoules per mole, we need to multiply by the conversion factor. The conversion factor is given by 1 J/mol = 1 kg m²/s²/mol. Additionally, 1 kJ = 1000 J.

Energy (E) = (2.7416 × 10⁻³⁶ kg m²/s²/particles * mol) * (1 J/mol / 1 kg m²/s²) * (1 kJ / 1000 J)

= 2.7416 × 10⁻³⁶ * 10⁻³ * 10⁻³ kJ/mol

= 2.7416 × 10⁻⁸ kJ/mol
