Shearing stress is most likely to occur at this boundary. Therefore, option A is correct.

Shearing stress is defined as "a type of stress that acts coplanar with the material's cross-section." Shear stress is caused by shear forces. They are the same magnitude and opposite direction forces acting on opposite sides of a body. Shear stress is measured as a vector quantity.

A strike-slip fault is a dip-slip fault with a vertical dip in the fault plane caused by shear stresses. The San Andreas Fault in California is the world's most well-known strike-slip fault.

Thus, option A is correct.

The total enthalpy change for the reaction is 200 J.

During an exothermic reaction, heat is released from the system which leads to an increase in its temperature.

The enthalpy change during an exothermic reaction is given by the equation,

Q= m × S × ΔT

Here, Q ⇒ Enthalpy change during a reaction

m ⇒ Mass of the substance

S ⇒ Specific Heat Capacity of the system

ΔT ⇒ Change in temperature of the system

On applying the given values in the above equation, we get the value of enthalpy as

Q= 10 x 2 x 10

  = 200 J.

Hence, the total enthalpy change for the reaction is 200 J.

The work done by the gas is -0.0124 L·atm and the heat absorbed from the thermostat is also -0.0124 L·atm.

To find the work done by the gas and the heat absorbed from the thermostat, we can use the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat absorbed by the system minus the work done by the system.

First, let's calculate the change in volume. The gas is allowed to double in volume, so the final volume will be 2 times the initial volume. The initial volume is 0.0124 dm^3, so the final volume will be 2 * 0.0124 dm^3 = 0.0248 dm^3.

Next, we need to calculate the work done by the gas. The work done by a gas expanding or contracting against a constant external pressure can be calculated using the equation: work = -P * ΔV, where P is the constant external pressure and ΔV is the change in volume.

In this case, the external pressure is 1.0 atm and the change in volume is (0.0248 dm^3 - 0.0124 dm^3) = 0.0124 dm^3. So, the work done by the gas is: work = -1.0 atm * 0.0124 dm^3 = -0.0124 L·atm.

To find the heat absorbed from the thermostat, we can rearrange the first law of thermodynamics equation: heat = change in internal energy + work. Since the problem states that the gas is an ideal gas, we can assume that the internal energy change is only due to changes in temperature, which means the change in internal energy is zero.

Therefore, the heat absorbed from the thermostat is equal to the work done by the gas: heat = -0.0124 L·atm.

Answer:

because each atom of helium occupies space. ... State a change in pressure that will cause the helium in the cylinder to behave more like an ideal gas.

Explanation:

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, the sample of helium can not be compressed to zero volume because each atom of helium occupies space.

Ideal gas equation is the mathematical expression that relates pressure volume and temperature. There is no force of attraction between the particles. The sample of helium can not be compressed to zero volume because each atom of helium occupies space.

Mathematically the relation between Pressure, volume and temperature can be given as

PV=nRT

P = pressure of gas

V= volume of gas

n =number of moles of gas

the number of moles of EDTA required to titrate the water sample is 0.0000872 moles.

We can use the equation for molarity to calculate the number of moles of EDTA required to titrate the water sample:

Molarity = moles of solute / liters of solution

First, we need to calculate the number of liters of EDTA solution used in the titration:

19.840 mL = 19.840 mL x (1 L / 1000 mL) = 0.019840 L

Next, we can use the equation for molarity to solve for the number of moles of EDTA:

Molarity = 4.395x

\( {10}^{3} \)

M

Liters of solution = 0.019840 L

moles of solute = Molarity x liters of solution

moles of EDTA = (4.395x

\( {10}^{ - 3} \)

M) x (0.019840 L) = 8.720x

\( {10}^{ - 5} \)

moles

Therefore, the number of moles of EDTA required to titrate the water sample is 8.720x

Explanation:

The heat required to raise the temperature of nitrogen gas from 50 K to 100 K at constant pressure is 417.84 J. The change in enthalpy of this process is 834.00 J. If the process proceeds at constant volume, the heat required is also 417.84 J. No work is done by the gas in the constant volume process.

To calculate the heat required at constant pressure, we use the heat capacity at constant pressure (Cp). The heat capacity at constant pressure represents the amount of heat required to raise the temperature of one mole of a substance by 1 degree Celsius. By multiplying the heat capacity at constant pressure (29.1 J/mol-C) by the change in temperature (50 K to 100 K = 50 K), we can calculate the heat required: 29.1 J/mol-C × 50 K = 1455 J.

The change in enthalpy (ΔH) of the process can be determined by the equation ΔH = nCpΔT, where n is the number of moles, Cp is the heat capacity at constant pressure, and ΔT is the change in temperature. In this case, we are considering one mole of nitrogen gas, so n = 1. By substituting the values, we get ΔH = 1 mol × 29.1 J/mol-C × 50 K = 1455 J.

When the process proceeds at constant volume, the heat required is the same as at constant pressure because the heat capacity at constant volume (Cv) and the heat capacity at constant pressure (Cp) for an ideal gas are related by the equation Cp - Cv = R, where R is the gas constant. Therefore, the heat required at constant volume is also 417.84 J.

In the constant volume process, no work is done by the gas because there is no change in volume. Work is given by the equation W = -ΔV × P, where ΔV is the change in volume and P is the pressure. Since ΔV is zero, the work done is also zero.

The molality of an aqueous solution that is 6.2% by mass calcium chloride with 1.18 g/mL density is 0.0528 mol/kg.

To calculate the molality of an aqueous solution of calcium chloride, we need to know the mass of solute (calcium chloride) in the solution and the mass of solvent (water) in the solution.

First, let's convert the concentration from percentage by mass to grams of solute per kilogram of solvent:

6.2% = 6.2 g/100 g = 0.062 g/g = 0.062 g/1000 g = 0.062 g/kg

Next, we need to determine the mass of water in the solution. We can use the density of the solution to do this. Assuming the volume of the solution is 1 mL, we have:

mass of water = volume * density = 1 mL * 1.18 g/mL = 1.18 g

Finally, we can use the mass of solute and mass of solvent to calculate the molality:

molality = moles of solute / kilograms of solvent = 0.062 g / 1.18 g = 0.0528 mol/kg (rounded to four decimal places)
