The partial pressures of each gas are approximately:

P(N₂) ≈ 14.74 atm

P(O₂) ≈ 8.10 atm

P(H₂) ≈ 2.68 atm

To determine the partial pressures of each gas, we can use the ideal gas law equation:

PV = nRT

where:

P is the pressure,

V is the volume,

n is the number of moles,

R is the ideal gas constant (0.0821 L·atm/(mol·K)),

and T is the temperature in Kelvin.

Volume (V) = 12.75 L

Temperature (T) = 215°C = 215 + 273.15 = 488.15 K

For nitrogen (N₂):

Number of moles (n) = 4.55 mol

Using the ideal gas law equation, we can calculate the partial pressure of nitrogen (P(N₂)):

P(N₂) = (n(N₂) * R * T) / V

= (4.55 mol * 0.0821 L·atm/(mol·K) * 488.15 K) / 12.75 L

≈ 14.74 atm

For oxygen (O₂):

Number of moles (n) = 2.72 mol

Using the ideal gas law equation, we can calculate the partial pressure of oxygen (P(O₂)):

P(O₂) = (n(O₂) * R * T) / V

= (2.72 mol * 0.0821 L·atm/(mol·K) * 488.15 K) / 12.75 L

≈ 8.10 atm

For hydrogen (H₂):

Number of moles (n) = 1.117 mol

Using the ideal gas law equation, we can calculate the partial pressure of hydrogen (P(H₂)):

P(H₂) = (n(H₂) * R * T) / V

= (1.117 mol * 0.0821 L·atm/(mol·K) * 488.15 K) / 12.75 L

a). High water demand in cities can lead to water scarcity.

b). The device then calculates the rate of water vapor leaving the leaf by measuring the humidity changes in the chamber.

c). The evaporation from the lake is 1.87 mm/hr, and the evaporation per day when the wind speed is 3.5m/s at 4 meters height is 71 mm.

a). High water demand in cities can lead to water scarcity. which is why measures should be taken to minimize water loss through evaporation. Below are three methods to help minimize evaporation:

1. Using covers to protect the water surface from solar radiation, wind and air currents.

2. Decreasing the water surface area.

3. Changing the shape of the water storage surface so that the surface area of the storage unit is minimal.

b) Transpiration is a physiological process in which plants give off water vapour through their leaves.

One method used to measure it is by gravimetric methods.

To measure transpiration, you can use a device called the porometer which is a device that measures the rate of water vapor leaving the leaf.

The porometer works by placing it on the plant leaf and then sealing it against the leaf surface.

The device then calculates the rate of water vapor leaving the leaf by measuring the humidity changes in the chamber.

c) To calculate the evaporation rate, we can use the following empirical equation:

E = P*(0.622e/(P - e)) * (w/273 + t)

where E is evaporation,

P is atmospheric pressure,

e is vapor pressure,

w is wind speed, and

t is temperature in degrees Celsius.

The given mean daily wind speed, mean air temperature, and the mean relative humidity at 2metres above the surface are:

3.0m/s, 18.0°C, and 65% respectively.

Vapor pressure is obtained from the relative humidity as follows:

e = 0.65 * es, where es is the saturation vapor pressure.

P = 101.3 kPa is the atmospheric pressure at sea level. es can be calculated using the Clausius-Clapeyron equation as:

es = 6.112 * exp(17.67t / (t + 243.5))

where t is temperature in degrees Celsius.

Thus es = 23.73 kPa and

e = 15.42 kPa.

Substituting the given values into the equation:

E = 101.3 * (0.622 * 15.42/(101.3 - 15.42)) * (3.0/273 + 18)

= 1.87 mm/hr

To calculate the evaporation per day when the wind speed is 3.5m/s at 4 meters height,

we can use the empirical formula for Lake Kariba as follows:

E = 0.57 U₁₀ (e - E/0.85) where U₁₀ is the wind speed at 10 meters height and E is the evaporation rate obtained above.

Using the given data, U₁₀ = Uz(10/z)0.143

where Uz is the wind speed at the height z, and

we take z to be 4 meters.

U₁₀ = 3.5(10/4)0.143

= 4.44 m/s

Substituting U₁₀ and E into the equation:

1.87 = 0.57 * 4.44 (e - 1.87/0.85)

The equation can be rearranged to obtain e = 2.96 mm/hr.

Therefore, the evaporation rate per day when the wind speed is 3.5m/s at 4 meters height is:

Evaporation per day = e * 24

= 2.96 * 24

= 71 mm.

Therefore, the evaporation from the lake is 1.87 mm/hr, and the evaporation per day when the wind speed is 3.5m/s at 4 meters height is 71 mm.

The molar mass of the unknown compound is 73.8 g/mol.

Given: Mass (m) = 1.44 g

  Volume (V) = 573 mL

   Pressure (P) = 809 mmHg

      Temperature (T) = 44.8 ∘C

The Ideal Gas Law is defined as

                            PV = nRT where P = pressure V = volume R = gas constant T = temperature n = moles of gas.

The first step is to convert the given volume into liters because the value of R used in the ideal gas law has units of      

                                        L•atm/mol•K.1 m

                                          L = 0.001 L573 m

                                          L = 0.573 L

Let's convert the temperature from degrees Celsius to Kelvin by adding 273.150.15 K = 318.95 K

Now the Ideal Gas Law can be written as:

                                     PV = nRTn = (PV)/(RT)

Substitute the given values: n = (0.809 atm x 0.573 L)/((0.0821 L•atm/mol•K) x 318.15 K)

                                            n = 0.0195 mol

Let's use the formula of molar mass.

                                     Molar mass = mass/moles

Substitute the given values. molar mass = 1.44 g/0.0195 mol

                                      molar mass = 73.8 g/mol

Therefore, the molar mass of the unknown compound is 73.8 g/mol. This is the required answer.

The maximum flexural stress of the rectangular beam can be determined by analyzing the shear and moment diagram and finding the maximum shear and moment values.

Analyze the Shear and Moment Diagram

To find the maximum shear and moment values, we need to analyze the shear and moment diagram for the rectangular beam. The shear diagram represents the variation of shear forces along the length of the beam, while the moment diagram represents the variation of bending moments. By examining these diagrams, we can identify the maximum values.

Identify Maximum Shear and Moment Values

In the shear diagram, the maximum shear value occurs at the point where the shear force is highest. Similarly, in the moment diagram, the maximum moment value occurs at the point where the bending moment is highest. By locating these points on the diagrams, we can determine the maximum shear and moment values.

Calculate Maximum Flexural Stress

Once we have obtained the maximum shear and moment values, we can calculate the maximum flexural stress using the formula:

Flexural Stress = (Maximum Moment) * (Distance from Neutral Axis) / (Moment of Inertia)

The distance from the neutral axis can be determined based on the dimensions of the rectangular beam (width and depth). The moment of inertia depends on the cross-sectional shape of the beam and can be calculated using standard formulas.

Now, we can simplify the equation by cross-multiplying:

0.4(2a - 1) < a + 5

0.8a - 0.4 < a + 5

0.8a - a < 5 + 0.4

-0.2a < 5.4

a > 5.4/-0.2

a > -27

So, we have determined that a must be greater than -27. However, we are looking for a specific value of a that satisfies the inequality.

To find the exact value, we can use trial and error or substitute values into the original equation. After evaluating different values, we find that a ≈ -0.474 satisfies the inequality.

Step-by-step explanation:

First, you have to find out if the angles of the triangle add up to 180. If so, then it is a triangle. If not, the angles are impossible and they can not be inserted into a triangle.

An equilateral triangle is a triangle where all of its angles are 60 degrees. (60, 60, 60)

A Scalene triangle is a triangle that has no matching angles (none of the angles are the same value. (59, 41, 80)

An isosceles triangle is a triangle that has two angles that are the same value (45, 45, 90)

Hence, the answer must be a Scalene Triangle.

The value of x in the equilateral triangle in radical form is  [tex]\frac{10\sqrt{3} }{3}[/tex].

The figure in the image is a right an equilateral triangle, meaning all its three sides are equal.

Since all its three sides are equal, each sides is x.

Meaning half of each side is x/2.

Dividing the equilateral triangle into two wqual halves forms a right triangle:

Hypotenuse = x

Leg 1 = 5

Leg 2 = x/2

Using pythagorean theorem, we can solve for x:

( hypotenuse )² = ( leg 1 )² + (leg 2 )²

x² = 5² + ( x/2 )²

x² = 5² + ( x/2 )²

x² = 5² + x²/2²

x² = 25 + x²/4

x² - x²/4 = 25

3x²/4 = 25

3x² = 25 × 4

3x² = 100

x² = 100/3

x = √(100/3)

A small average particle size in the starting powder promotes sintering and densification during the firing of ceramics. It maximizes the bulk density of the powder compact and enhances the thermodynamic driving force for sintering. Hence, options A and B both are correct.

To promote sintering and densification during the firing of ceramics, it is desirable to have a small average particle size for the starting powder. This is because a smaller particle size maximizes the bulk density of the powder compact, which, in turn, increases the overall density of the final fired article.

Sintering is a process used to create ceramic materials that are difficult to mold through conventional means. It involves subjecting the powder to high temperatures, causing the particles to bond together and form a solid structure. The small particle size of the starting powder enhances the bulk density of the powder compact, leading to improved densification in the final fired product.

To achieve effective sintering, it is important to maximize the thermodynamic driving force. Sintering is an energy-intensive process, as it requires a high-energy state to fuse the particles together. A small particle size increases the surface area of the powder, promoting evaporation and condensation as sintering mechanisms. This enhances the thermodynamic driving force and facilitates the sintering process.

It should be noted that the average coordination number of the particles is not influenced by the particle size, so it does not directly promote sintering. Additionally, a small average particle size does not necessarily result in reduced grain growth. Grain growth may occur if the temperature during sintering is too high, which can be a factor independent of the particle size.

In conclusion, a small average particle size in the starting powder is beneficial for sintering and densification during the firing of ceramics. It maximizes bulk density, promotes evaporation-condensation mechanisms, and increases the thermodynamic driving force for sintering. Hence, option A and B both are correct.

Answer: a) p decreases and b) v decreases

Step-by-step explanation: For a), you can test whether p increases or decreases based on the position of v. If v=1 then p=4/1=4 but that p number will change as v also changes. You can try other similar numbers for v like 2 and 3 and you can see that p gets fractions that continuously get smaller. This is a direct relationship in proportion so p decreases and v increases.

For b), use the same logic as a). You can ask yourself, "If p is increasing, what do I already know about the relationship from problem A?" Now we know that as v rises in value, p gets smaller, so the opposite must be true here. As P gets larger, v must get smaller and decrease in value.

Due to the lack of specific information regarding the beam section and design code, a direct answer, calculation, and conclusion cannot be provided at this time. To perform an accurate analysis, please provide the necessary details, and I will be happy to assist you further.

Since I do not have the specific details of the beam section and design code, I am unable to provide a detailed explanation and perform the required calculations. The analysis of a beam's weight, moment capacity, shear capacity, web crippling, web yielding, and web sidesway buckling involves a comprehensive structural analysis that considers the properties and behavior of the specific beam section and follows the relevant design code provisions.

To estimate the beam weight, you can use the formula:

Weight = Length × Weight per unit length

Given that the length of the beam is 32 ft and the weight per unit length is 60 plf (pounds per linear foot), you can calculate the estimated beam weight.

For selecting the lightest section based on moment capacity, you would need the section properties (such as the moment of inertia) of various available beam sections. Comparing the moment capacity of each section based on the applied loads can help identify the lightest section that can safely resist the moments.

Similarly, for checking the section's shear capacity using Allowable Stress Design (ASD), the shear strength of the section should be compared to the applied shear force.

The determination of the minimum length of bearing required at the supports from the standpoint of web crippling and web yielding depends on the specific beam section and its design parameters.

Lastly, checking web sidesway buckling involves analyzing the stability of the web under lateral loads, considering factors such as the slenderness ratio and the properties of the material.

The molecular formula of the compound is C₈H₁₀N₄O₂. The correct answer is option b.

To determine the molecular formula of the compound, we need to find the empirical formula first. The empirical formula represents the simplest whole-number ratio of atoms in a compound.

Calculate the number of moles of each element:

Carbon (C): 49.48% of 194.19 g = 96.09 g

Moles of C = 96.09 g / 12.01 g/mol = 7.999 mol (approximately 8 mol)

Hydrogen (H): 5.19% of 194.19 g = 10.08 g

Moles of H = 10.08 g / 1.01 g/mol = 9.981 mol (approximately 10 mol)

Nitrogen (N): 28.85% of 194.19 g = 56.02 g

Moles of N = 56.02 g / 14.01 g/mol = 3.998 mol (approximately 4 mol)

Oxygen (O): 16.48% of 194.19 g = 32.02 g

Moles of O = 32.02 g / 16.00 g/mol = 2.001 mol (approximately 2 mol)

Find the simplest whole-number ratio:

Divide the number of moles of each element by the smallest number of moles (in this case, 2 mol) to obtain the simplest whole-number ratio:

C: 8 mol / 2 mol = 4

H: 10 mol / 2 mol = 5

N: 4 mol / 2 mol = 2

O: 2 mol / 2 mol = 1

The empirical formula is C₄H₅N₂O

To determine the molecular formula, we need to compare the empirical formula's molar mass to the given molecular weight (194.19 g/mol).

Empirical formula mass: C₄H₅N₂O = 4(12.01 g/mol) + 5(1.01 g/mol) + 2(14.01 g/mol) + 16.00 g/mol = 98.10 g/mol

To find the molecular formula, we divide the molecular weight by the empirical formula mass:

Molecular weight / Empirical formula mass = 194.19 g/mol / 98.10 g/mol = 1.98 (approximately 2)

Multiply the subscripts in the empirical formula by 2 to obtain the molecular formula:

C₄H₅N₂O * 2 = C₈H₁₀N₄O₂

Therefore, the molecular formula of the compound is C₈H₁₀N₄O₂ (option b).

At STP, 9g of diborane (B2H6) occupies approximately 4.48 liters. At 10°C and a pressure of 0.55 atm, the volume it occupies can be calculated using the ideal gas law.

To find the volume of diborane (B2H6) at STP, we can use the molar mass of diborane (B2H6), which is approximately 27.67 g/mol. First, we need to convert the mass of 9g into moles by dividing it by the molar mass:

9g / 27.67 g/mol = 0.325 mol

Next, we can use the ideal gas law equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/(mol·K)), and T is the temperature in Kelvin.

At STP, the pressure is 1 atm and the temperature is 273 K. Plugging these values into the ideal gas law equation:

(1 atm) * V = (0.325 mol) * (0.0821 L·atm/(mol·K)) * (273 K)

Simplifying the equation:

V = (0.325 mol) * (0.0821 L·atm/(mol·K)) * (273 K) / (1 atm)
V ≈ 4.48 L

Therefore, at STP, 9g of diborane (B2H6) occupies approximately 4.48 liters.

To find the volume at 10°C and a pressure of 0.55 atm, we can use the same ideal gas law equation, but this time we need to convert the temperature from Celsius to Kelvin.

10°C + 273 = 283 K

Plugging in the new temperature and the given pressure value:

(0.55 atm) * V = (0.325 mol) * (0.0821 L·atm/(mol·K)) * (283 K)

Simplifying the equation:

V = (0.325 mol) * (0.0821 L·atm/(mol·K)) * (283 K) / (0.55 atm)
V ≈ 13.1 L

Therefore, at 10°C and a pressure of 0.55 atm, 9g of diborane (B2H6) occupies approximately 13.1 liters.
