The equilibrium partial pressure of \($NH_3$\) is 0.0106 atm. \($K_c=\frac{[NH_3]^2}{[N_2][H_2]^3},$\) and \($[NH_3]=1.32\times10^{-4}\frac{mol}{L}.$\)

To decide the harmony halfway strain of \($NH_3$\) in the response vessel, we really want to think about the decent condition for the response:

\($N_2(g) + 3H_2(g)\) rightleftharpoons \(2NH_3(g)$\).

At harmony, the paces of the forward and invert responses are equivalent, and the centralizations of the reactants and items never again change. The harmony steady articulation for this response is:

\($K_c = \frac{[NH_3]^2}{[N_2][H_2]^3}$\)

We can utilize the underlying tensions of \($N_2$\) and \($H_2$\) to ascertain their fixations utilizing the best gas regulation:

\($[N_2] = \frac{P_{N_2}}{RT} = \frac{0.900 atm}{0.08206 \frac{L\cdot atm}{mol\cdot K} \times 648 K} = 0.0149 \frac{mol}{L}$\)

\($[H_2] = \frac{P_{H_2}}{RT} = \frac{0.500 atm}{0.08206 \frac{L\cdot atm}{mol\cdot K} \times 648 K} = 0.0083 \frac{mol}{L}$\)

Subbing these fixations and the harmony steady articulation into the articulation for \($K_c$\), we get:

\($K_c = \frac{[NH_3]^2}{[N_2][H_2]^3}$\)

\($K_c = \frac{([NH_3]/0.0149 \frac{mol}{L})^2}{0.0149 \frac{mol}{L} \times (0.0083 \frac{mol}{L})^3}$\)

\($K_c = \frac{[NH_3]^2}{1.05\times10^{-10}}$\)

Addressing for \($[NH_3]$\), we get:

\($[NH_3] = \sqrt{K_c \times [N_2] \times [H_2]^3}$\)

\($[NH_3] = \sqrt{1.05\times10^{-10} \times 0.0149 \frac{mol}{L} \times (0.0083 \frac{mol}{L})^3}$\)

\($[NH_3] = 1.32\times10^{-4} \frac{mol}{L}$\)

At long last, we can switch this fixation over completely to a halfway tension utilizing the best gas regulation:

\($P_{NH_3} = [NH_3] \times \frac{RT}{P}$\)

\($P_{NH_3} = (1.32\times10^{-4} \frac{mol}{L}) \times \frac{0.08206 \frac{L\cdot atm}{mol\cdot K} \times 648 K}{1 atm}$\)

\($P_{NH_3} = 0.0106 atm$\)

Consequently, the harmony halfway tension of \($NH_3$\) in the response vessel is 0.0106 atm.

The moisture content of the soil sample is approximately 27.6%. This means that the soil sample contains 27.6% water by weight.

The initial wet weight of the soil sample was 274.1 g. After drying overnight in an oven, the sample weighed 214.7 g. To calculate the moisture content of the soil sample, we can use the following formula:

Moisture Content (%) = (Wet Weight - Dry Weight) / Dry Weight * 100

Substituting the given values into the formula, we have:

Moisture Content (%) = (274.1 g - 214.7 g) / 214.7 g * 100

Simplifying the calculation:

Moisture Content (%) = 59.4 g / 214.7 g * 100

Moisture Content (%) ≈ 27.6%

Therefore, the moisture content of the soil sample is approximately 27.6%. This means that the soil sample contains 27.6% water by weight.

A hydraulic system's force is calculated using the equation f = p * a, where f stands for force, p for pressure, and a for area.

This equation is derived from Pascal's law, which states that the pressure applied to a fluid is transmitted equally throughout the fluid in all directions.

Therefore, the pressure applied to the fluid in a hydraulic system is transmitted to the piston, which generates a force that is directly proportional to the pressure and the piston's area. This equation can be used to calculate the force of a hydraulic system for various applications, such as lifting heavy objects or operating machinery.

Whole wheat loaves accounted for approximately 23.08% of the total bread sold.

To determine the percentage of whole wheat loaves out of the total bread sold, we need to calculate the proportion of whole wheat loaves and express it as a percentage. In July, the bakery sold 2070 loaves of whole wheat bread, and in total, they sold 9000 loaves of bread.

To find the percentage, we divide the number of whole wheat loaves by the total number of loaves and multiply by 100:

Percentage of whole wheat loaves = (2070 / 9000) * 100 = 23.08%

Therefore, approximately 23.08% of the bread sold were whole wheat loaves.

To determine the number of moles in 44.0 grams of sugar, we need to know the molar mass of sugar. Since sugar is a generic term and can refer to different compounds, let's assume we are referring to sucrose (C12H22O11), which is a common type of sugar.

The molar mass of sucrose (C12H22O11) can be calculated by summing up the atomic masses of all its constituent elements:

(12.01 g/mol × 12) + (1.01 g/mol × 22) + (16.00 g/mol × 11) = 342.34 g/mol

Now, using the molar mass of sucrose, we can calculate the number of moles:

Number of moles = Mass (in grams) / Molar mass

Number of moles = 44.0 g / 342.34 g/mol = 0.1284 mol

Therefore, there are approximately 0.1284 moles of sugar in 44.0 grams of sucrose.

The electronegativity periodic table is a chart that arranges elements according to their electronegativity, which is a measure of an atom's ability to attract electrons to itself. Electronegativity is a chemical property that reflects the relative tendency of an atom to draw electrons towards itself when it forms a chemical bond with another atom.

The electronegativity values are usually determined using the Pauling scale, which was developed by Linus Pauling and is widely used in chemistry. In this scale, the electronegativity of an element ranges from 0.7 for cesium to 4.0 for fluorine, with increasing electronegativity moving from left to right across a period and increasing as one moves down a group.

The electronegativity values can be useful in understanding chemical bonding and the behavior of molecules. For example, elements with high electronegativity values tend to form ionic bonds, while elements with low electronegativity values tend to form covalent bonds. Additionally, the electronegativity difference between two bonded atoms determines the type of bond, with larger differences indicating polar covalent bonds and smaller differences indicating nonpolar covalent bonds.

The reaction is given as:

AgNO₃  +  NH₄Cl  ---->   AgCl  +  NH₄NO₃

given that :

molarity of AgNO₃ = 0.500 M

volume = 31.2 mL = 0.0312 L

moles of AgNO₃  = 0.500 × 0.0312

                             = 0.0156 mol

moles of NH₄Cl = molarity × volume

                          = 0.300 × 0.025

                          = 0.0075 mol

1 mole of NH₄Cl = 1 mole of AgCl

mass of AgCl = moles × molar mass

                      = 0.0075 × 143.32

                      = 1.074 g

Using a technique called "dimensional analysis" ; as follows:

________________________

→  " \(\frac{2.34 mol Al}{1} * \frac{6.022*10^{23}atoms Al}{1 mol Al} = ?\)  

________________________

The units "mol Al" ["moles of aluminum"] cancel out; and we have:

________________________

→  "\([(2.34) * (6.022 * 10^{23})] = ?\) atoms of Al [aluminum].

________________________

Note that by definition: 1 (one) "mole" (abbreviated "mol") of anything consists of " \(6.022*10^{23}\) " units " of that particular thing.

 This number:  6.022*10^{23} —is known as:  "Avogadro's number".

________________________

→  [ 2.34 * 6.022 * 10^23] ;

     = 1.409148 * 10^24 ;

                → Round to 3 (Three) significant figures;

                →  since: "2.34" has 3 (Three) significant figures;

                  →  to get: " \(1.41 *10^{24}\)  atoms of aluminum (Al).
