During a dry year which plants will most likely be able to survive in clay soil

Answer:

1.00

Explanation:

I honestly have no idea. I found this online and apparently it was correct. I thought at first I would use d = RT/(Nₐ * P *π (2r)². Since all values besides T are constant, I thought the ratio would just be (273+80)/273 since 273 is standard temperature in Kelvin. However, I think the answer is 1.00 since the pressure would also increase since it is a rigid container, effectively cancelling out the increase in temperature.

The ratio of the mean free path of air molecules at 80 °C to their mean free path at STP is approximately 0.934.

The mean free path (MFP) of gas molecules is the average distance they travel between collisions with other molecules. It depends on the temperature, pressure, and molecular size of the gas. The MFP of air molecules at standard temperature and pressure (STP) is about 68 nanometers.

To find the ratio of the mean free path of air molecules at 80 °C to their mean free path at STP, we need to use the following formula:

Ratio = (MFP at 80 °C) / (MFP at STP)

The MFP at 80 °C can be calculated using the kinetic theory of gases, which states that:

MFP = (k × T) / (sqrt(2) × pi × d² × P)

where k is Boltzmann's constant, T is the temperature in Kelvin, d is the molecular diameter, and P is the pressure.

For air molecules, d is about 0.364 nanometers. At 80 °C (353 K), the pressure of air is about 101.3 kPa. Plugging these values into the formula, we get:

MFP at 80 °C = (1.38 × 10⁻²³ J/K ×353 K) / (sqrt(2) × 3.14 ×(0.364 × 10⁻⁹m)² ×101.3 × 10³ Pa)

MFP at 80 °C = 63.5 nanometers

Now we can calculate the ratio:

ratio = (MFP at 80 °C) / (MFP at STP)

ratio = 63.5 nm / 68 nm

ratio ≈ 0.934

Therefore, the ratio of the mean free path of air molecules at 80 °C to their mean free path at STP is approximately 0.934.

Answer: 2.62 moles

Explanation:

For every 2 moles of ammonia that are produced, 1 mole of nitrogen is consumed.

This means that if 5.24 moles of ammonia are produced, 5.24/2=2.62 moles of nitrogen are consumed.

The equilibrium constant gives us an idea of the extent of reaction. For the reaction; 2GeCl4(g) = 2Ge(g) + 4Cl2 (g), the equilibrium constant is 1 * 10^-20.

The equilibrium constant gives us an idea of the extent of the conversion of reactants to products in a reaction.

In this case, we know that 2GeCl4(g) = 2Ge(g) + 4Cl2 (g) is the reverse of Ge (g) + 2Cl2 (g) <-> GeCl4 (g) hence we only need to invert the value of the equilibrium constant and raise it to power 2 to have 1 * 10^-20.

The equilibrium constant of the reaction is 1.21 * 10^6 while the change in free energy is -34.7 kJ.

The equilibrium constant shows the extent of conversion of reactants to products.

Now we know from the Nernst equation that;

Ecell = E°cell - 0.0592/n logQ

E°cell = 0.52−0.16=0.36 V

Since Ecell = 0 V at equilibrium,

0 = 0.36 - 0.0592/1 log K

0.36  = 0.0592/1 log K

log K = 0.36/ 0.0592

K = antiog (0.36/ 0.0592)

K = 1.21 * 10^6

ΔG = -RT lnK

ΔG =-(8.314 * 298 * ln1.21 * 10^6)

ΔG =-34.7 kJ

A video-disc player that is not playing still uses 6.0 W of power. The current is  0.05 A.

What is Power?

The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings.  A scalar quantity is power.

Power is related to other factors; for instance, the power required to move a ground vehicle is equal to the product of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.

A motor's output power is calculated by multiplying its torque output by the angular velocity of its output shaft. Similar to how the power expended in an electrical component of a circuit is the result of the current.

Determine the amount of moles of HCl in 40.0 grams. The molecular weight of HCl is 36.46 g/mol:

[tex]\displaystyle 40.0\text{ g HCl} \cdot \frac{1\text{ mol HCl}}{36.46\text{ g HCl}} = 1.10\text{ mol HCl}[/tex]
