the concentration of argon gas in a saturated solution is approximately 6.26×10⁻²  and the Henry's law constant is approximately 6.26×10⁻² atm⁻¹.

What is Henry Law?

The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.

In the given scenario, 6.26×10⁻²  liters of argon gas were dissolved in 1.0 liters of water to form a saturated solution. The pressure of argon gas was 1.0 atm and the temperature was 25 degrees Celsius.

To analyze this situation, we must consider Henry's law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.

By Henry's law, we have the equation:

C = k * P

Where C is the concentration of the dissolved gas in the solution, k is the proportionality constant (Henry's law constant) and P is the partial pressure of the gas.

With regard to it regarding to it:

Partial pressure of argon gas (P) = 1.0 atm

Volume of argon gas (V) = 6.26×10⁻²  liters

Water volume (Vw) = 1.0 liter

The concentration of argon gas in a saturated solution can be subscript using the equation:

C = V / Vw

Enter the values:

C = (6.26×10⁻²  liters) / (1.0 liter)

C ≈ 6.26×10⁻²

We can now use Henry's law to determine the value of the Henry's law constant (k):

C = k * P

(6.26×10⁻² ) = k * (1.0 atm)

k ≈ (6.26×10⁻² ) / (1.0 atm)

k ≈ 6.26×10⁻²  atm⁻¹

Therefore, the concentration of argon gas in a saturated solution is approximately 6.26×10⁻²  and the Henry's law constant is approximately 6.26×10⁻²  atm⁻¹.

The value of ΔG at 298 K for a reaction mixture containing 1.9 atm N2, 1.6 atm H2, and 0.65 atm, the answer is (a) -3.86 × 10^3.

NH3 can be calculated using the equation:

ΔG = ΔG° + RT ln(Q)

where ΔG is the standard Gibbs free energy change, ΔG° is the standard Gibbs free energy change at standard conditions, R is the gas constant, T is the temperature in Kelvin, and Q is the reaction quotient.

In this case, we are given ΔG° as -33.3 kJ/mol. To calculate Q, we need to use the partial pressures of the gases in the reaction mixture. The reaction stoichiometry tells us that the ratio of the partial pressures of N2, H2, and NH3 is 1:3:2. Therefore, we can write:

Q = (P(NH3))^2 / (P(N2) * P(H2)^3)

Plugging in the given values of P(N2) = 1.9 atm, P(H2) = 1.6 atm, and P(NH3) = 0.65 atm, we can calculate Q. Then, using the value of R = 8.314 J/(mol·K) and the temperature T = 298 K, we can substitute these values into the equation and solve for ΔG.

The calculated value of ΔG at 298 K for the given reaction mixture is approximately -3.86 × 10^3 J/mol. This value is equivalent to -3.86 kJ/mol. Therefore, the answer is (a) -3.86 × 10^3.

In this case, the partial pressures of nitrogen (N2), oxygen (O2), and helium (He) are given as 219 torr, 106 torr, and 244 torr, respectively. The total pressure of the gas mixture is 569 torr.

The total pressure of a gas mixture is the sum of the partial pressures of its individual components. In this case, the partial pressures of nitrogen (N2), oxygen (O2), and helium (He) are given as 219 torr, 106 torr, and 244 torr, respectively.

To find the total pressure, we simply add these partial pressures together:

Total pressure = Partial pressure of N2 + Partial pressure of O2 + Partial pressure of He

            = 219 torr + 106 torr + 244 torr

            = 569 torr

Therefore, the total pressure of the gas mixture is 569 torr.

Emerging scientific ideas are new theories or ideas that are gaining attention in the scientific community, but have not yet been fully accepted or confirmed.

Emerging ideas refer to the new and innovative ideas or theories that have yet to gain full scientific acceptance. While a scientific consensus is a view or theory that has been universally accepted and confirmed by multiple experiments or research, an emerging scientific idea is a new and unproven theory or idea that is gaining attention in the scientific community. These emerging ideas may also be referred to as scientific hypotheses. In contrast to scientific consensus, emerging scientific ideas have not yet been subjected to rigorous testing and confirmation.

They are generally proposed to explain new observations or experimental results, which have not yet been fully understood or explained by established scientific theories. Emerging scientific ideas can have the potential to challenge the current scientific consensus. If an emerging scientific idea is found to be valid, it can ultimately lead to the establishment of a new scientific consensus. For example, the emerging scientific idea of the Higgs boson particle led to the discovery of a new field in particle physics, which is now an established scientific consensus.

The entropy change for a 555. g,the final temperature of the 555.0 g sample of acetone is 21.11°C.

To calculate the final temperature of a 555.0 g sample of acetone (CH3COCH3) with an entropy change of 150.0 J/K, we can use the following steps:

Step 1: Convert the mass of acetone to moles
First, determine the molar mass of acetone: CH3COCH3 has 3 carbons (12.01 g/mol each), 6 hydrogens (1.01 g/mol each), and 1 oxygen (16.00 g/mol). The molar mass is (3*12.01 + 6*1.01 + 16.00) = 58.08 g/mol.

Now, convert the mass of acetone to moles:
moles = mass / molar mass = 555.0 g / 58.08 g/mol = 9.55 mol

Step 2: Calculate the heat change (q)
Use the entropy change (ΔS) and the definition of entropy to find the heat change (q):
q = ΔS * T
Since ΔS = 150.0 J/K, we need to find T.

Step 3: Calculate the heat capacity (C)
Use the molar heat capacity (Cp) and the number of moles to find the total heat capacity (C) of the sample:
C = Cp * moles = 141.5 J/molK * 9.55 mol = 1350.73 J/K

Step 4: Calculate the temperature change (ΔT)
Use the heat change (q) and the heat capacity (C) to find the temperature change (ΔT):
ΔT = q / C
Since we need to find T, we can rewrite this equation as:
T = q / C + T_initial
We know the initial temperature (T_initial) is 10.0°C.

Step 5: Calculate the final temperature (T_final)
Now, substitute the values into the equation to find the final temperature (T_final):
T_final = (150.0 J/K * T) / 1350.73 J/K + 10.0°C

After solving for T, we get:
T_final = 21.11°C

So, the final temperature of the 555.0 g sample of acetone is 21.11°C.

The number of atoms in one mole of hydrogen is 6.022 × 10²³. 2 moles of water contains 4 moles of hydrogen  thus, 1.2 × 10²⁴. Hence, the statement is false.

Any substance containing 6.022 × 10²³ number of atoms is called one mole of the substance. This number is called Avogadro number. Therefore one mole of every elements contains Avogadro number of atoms.

Thus, one mole of hydrogen gas contains 6.022 × 10²³ H₂.

One  mole of water contains  6.022 × 10²³  water molecules. One water molecule is made of two hydrogens and one oxygens. One mole of water contains 6.022 × 10²³  molecules.

Therefore, two moles of water contains 2 × 6.022 × 10²³ = 1.2 × 10²⁴  H₂ Therefore, the number of hydrogen atoms in one mole of  H₂ gas and two moles of water are not equal.

M1 = 12m

M2 = 0.15m

V1 = 30ml

V2 = ?

By putting the values in the equation as follows;

M1 × V1 = M2 × V2

Answer:

Only elements are pure substances.

Answer: c

Explanation:

answer is B value of approximation

solving

The heat of vaporization for water is 40.7 kJ/mol, which means that it takes 40.7 kJ of energy to convert 1 mole of water from a liquid to a gas phase.

The energy required to boil the water is given as 63.8 kJ.

We can set up a proportion using these values:

40.7 kJ/1 mol = 63.8 kJ/x mol

To solve for x (the number of moles of water), we can cross-multiply and solve the equation:

40.7 kJ * x mol = 63.8 kJ * 1 mol

x mol = (63.8 kJ * 1 mol) / 40.7 kJ

x mol ≈ 1.57 mol

Since we know the molar mass of water is approximately 18.015 g/mol, we can convert moles to grams:

1.57 mol * 18.015 g/mol ≈ 28.29 g

Therefore, the mass of the sample of water is approximately 28.29 grams.
