If 7 g of a gas at 2.0 ATM dissolves in 1 L of water at 25°C how much will dissolve in 2 L of water at 0.6 ATM if the temperature remains constant
Answers
The value of S2 is S₂ = 2.1 g/L.Approximately 2.1 g of the gas will dissolve in 2 L of water at 0.6 ATM, assuming the temperature remains constant.
To determine the amount of gas that will dissolve in 2 L of water at 0.6 ATM, we can use Henry's law, which states that the solubility of a gas is directly proportional to the partial pressure of the gas above the liquid.
According to Henry's law, the solubility of a gas can be represented as:S₁/P₁ = S₂/P₂,,where S₁ and S₂ are the solubilities of the gas at the respective pressures P₁ and P₂.Given that 7 g of the gas dissolves in 1 L of water at 2.0 ATM, we can consider this as our initial condition, denoted by S₁/P₁.
Now, we need to find the solubility at 0.6 ATM in 2 L of water, denoted by S₂/P₂.Since the temperature remains constant, we can assume that the solubility of the gas does not change. Therefore, we can rewrite the equation as:
S₁/P₁ = S₂/P₂,
Substituting the known values, we have:
(7 g/1 L)/(2.0 ATM) = S₂/(0.6 ATM),
Solving for S₂, we get:
S₂ = (7 g/1 L) * (0.6 ATM)/(2.0 ATM),
S₂ = 2.1 g/L.

0.28
0.798
0.178
0.142
0.881
0.61
and 0.812
Answers
Answer:
The cell potential for the given galvanic cell is 0.188 V.
Explanation:
To calculate the cell potential, we can use the Nernst equation:
Ecell = E°cell - (RT/nF)ln(Q)
where E°cell is the standard cell potential, R is the gas constant (8.314 J/mol·K), T is the temperature in Kelvin (25°C = 298 K), n is the number of moles of electrons transferred (in this case, n = 2), F is the Faraday constant (96,485 C/mol), and Q is the reaction quotient.
First, we need to write the half-reactions and their standard reduction potentials:
Sn4+(aq) + 2e- → Sn2+(aq) E°red = 0.15 V
Fe3+(aq) + e- → Fe2+(aq) E°red = 0.77 V
The overall reaction is the sum of the half-reactions:
Sn2+(aq) + 2Fe3+(aq) → Sn4+(aq) + 2Fe2+(aq)
The reaction quotient Q can be expressed as:
Q = [Sn4+][Fe2+]^2 / [Sn2+][Fe3+]^2
Substituting the given concentrations, we get:
Q = (0.00655)(0.01139)^2 / (0.0624)(0.0437)^2 = 0.209
Now we can calculate the cell potential:
Ecell = 0.15 V + 0.0592 V log([Fe2+]^2/[Fe3+]) + 0.0592 V log([Sn4+]/[Sn2+])
= 0.15 V + 0.0592 V log(0.01139^2/0.0437^2) + 0.0592 V log(0.00655/0.0624)
= 0.188 V
Therefore, the cell potential for the given galvanic cell is 0.188 V.
The cell potential for the given galvanic cell in which the given reaction occurs at 25 °C is 0.188 V.
How to the cell potential of galvanic cell?To find the cell potential, we take the Nernst equation:
Ecell = E°cell - (RT/nF)ln(Q)
In which R is the gas constant (8.314 J/mol·K) and E° cell is the standard cell potential.
T temperature in Kelvin (25°C = 298 K), and n is the number of moles of electrons transferred (n = 2), Q is the reaction quotient and F is the Faraday constant (96,485 C/mol).
Firstly, write the half-reactions and then their standard reduction potentials:
Sn⁴⁺(aq) + 2e⁻ → Sn²⁺(aq) E°red = 0.15 V
Fe³⁺(aq) + e⁻ → Fe²⁺(aq) E°red = 0.77 V
The overall reaction is the sum of the half-reactions:
Sn²⁺(aq) + 2Fe³⁺(aq) → Sn⁴⁺(aq) + 2Fe²⁺(aq)
The Q reaction quotient can be written as:
Q = [Sn⁴⁺][Fe²⁺]² ÷ [Sn²⁺][Fe²⁺]²
Substituting the given concentrations, we observe:
Q = (0.00655)(0.01139)² ÷ (0.0624)(0.0437)² = 0.209
Next, we can find the cell potential:
Ecell = 0.15 V + 0.0592 V log([Fe²⁺]²/[Fe³⁺]) + 0.0592 V log([Sn⁴⁺]/[Sn²⁺])
= 0.15 V + 0.0592 V log(0.01139²÷0.0437²) + 0.0592 V log(0.00655÷0.0624)
= 0.188 V
Thus, the cell potential for the given galvanic cell is 0.188 V.

Question 2 options:
4.0 L
0.9 L
0.8 L
0.5 L
Answers
Answer:
\( \boxed{\sf \: 0.8 \: litres }\)
Explanation:
Given:
intial Molarity of MgSO4 solution,
M1 = 0.5 M
Final molarity of MgSo4 solution
M2 = 0.2 M
in volume V2 = 2 Litres.
To find:
volume of the stock solution needed to make 2.0 L of 0.20M MgSO4=?
Solution:
M1V1 = M2V2
0.5 × V1 = 2 × 0.2
\(V_1 = \frac{2 \times 0.2}{0.5} \)
\(V_1 = \frac{ 0.4}{0.5} \)
\(V_1 = \frac{ 4}{5} \)
\(V_1 = 0.8L\)
Conclusion diluting 0.8 L (800 ml) of 0.5 M MgSO4 solution upto 2 Litre will decrease the molarity from 0.5 M to 0.2 M.
Hence Correct answer is 0.8 L
\(\sf \small \pink{Thanks }\: \green{for} \: \blue{joining} \: \orange{brainly } \: \red{community}!\)
Answer:
C) 0.8 L
Explanation:
To calculate the volume of the Magnesium Sulphate (MgSO₄) stock solution needed to make the desired concentration, we can use the dilation formula:
\(\boxed{\sf M_1V_1 = M_2V_2}\)
where:
M₁ = Initial molarity of the solution.V₁ = Initial volume of the solution.M₂ = Final molarity of the solution.V₂ = Final volume of the solution.Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution. The symbol for molarity is "M".
Given values:
M₁ = 0.5 MM₂ = 0.2 MV₂ = 2.0 LSubstitute the given values into the dilution formula and solve for V₁:
\(\sf 0.5\;M \cdot V_1=0.2\;M \cdot 2.0\;L\)
\(\sf V_1=\dfrac{0.2\;M \cdot 2.0\;L}{0.5\;M}\)
\(\sf V_1=\dfrac{0.4\;L}{0.5}\)
\(\sf V_1=0.8\;L\)
Therefore, the volume of the stock solution needed to make 2.0 L of 0.20 M MgSO₄ is 0.8 L.

find the ΔG°rxn for a reaction that has a K = 17.23 at 371 K. Is the reaction spontaneous. Note: R = 8.314 J/mol.K
Answers
The value of ΔG°rxn is - 6979 J/mol, and the reaction is spontaneous.
The change in Gibbs free energy (ΔG°rxn) for a reaction can be calculated using the equation;
ΔG°rxn = -RT ln(K)
where; R = gas constant = 8.314 J/mol.K
T = temperature in Kelvin (K)
K = equilibrium constant for the reaction
Given;
K = 17.23
T = 371 K
R = 8.314 J/mol.K
Plugging in the given values into the equation;
ΔG°rxn = - (8.314 J/mol.K) × (371 K) * ln(17.23)
Using a calculator, we can calculate the natural logarithm of 17.23:
ln(17.23) ≈ 2.848
Plugging this value back into the equation;
ΔG°rxn = - (8.314 J/mol.K) × (371 K) × 2.848
ΔG°rxn ≈ - 6979 J/mol
The negative value of ΔG°rxn indicates that the reaction is spontaneous, as ΔG°rxn < 0.
Therefore, the reaction will occur spontaneously in the forward direction at 371 K when the equilibrium constant (K) is 17.23.

Answers
Answer: 2 SO2 (g) + O2 (g) Kp = 7.69 If a vessel at this temperature initially ... and if the partial pressure of sulfur trioxide at equilibrium is 0.100 atm,
Explanation:
As sulfur dioxide has an equilibrium partial pressure of 0.100 atm. Hence, the partial pressure of O\(_2\) will be half of 0.100 atm, it is 0.05 atm.
What is partial pressure?Each gas that makes up a mixture of gases has a partial pressure, which would be the notional pressure of that gas as if it alone filled the original combination's complete volume at the same temperature.
The thermodynamic activity of a gas's molecules is gauged by its partial pressure. Gases react, disperse, and dissolve based on their partial pressures rather than the concentrations they have in liquids or other gas combinations.
2 SO\(_2\) (g) + O\(_2\) (g) → SO\(_3\) Kp = 7.69
As sulfur dioxide has an equilibrium partial pressure of 0.100 atm. Hence, the partial pressure of O\(_2\) will be half of 0.100 atm, it is 0.05 atm.
Therefore, 0.05 atm is the partial pressure of O\(_2\) .

To balance the equation and identify the type of reaction, let's start by assigning coefficients to each compound: 2H2O + 1SO3 -> 1H2SO4
To balance the equation, we need to ensure that the number of atoms on both sides is the same. Here, we have two hydrogen (H) atoms on the left side and two on the right side, so hydrogen is already balanced.
We have two oxygen (O) atoms on the left side and four on the right side, so we need to balance oxygen by adding a coefficient of 2 in front of the water molecule:
2H2O + 1SO3 -> 1H2SO4
Now the equation is balanced with two hydrogen, four oxygen, and one sulfur (S) atom on both sides.
The type of reaction represented by this equation is a combination or synthesis reaction. In a combination reaction, two or more substances combine to form a new compound. In this case, water (H2O) and sulfur trioxide (SO3) combine to form sulfuric acid (H2SO4).

Answers
The balanced redox reaction is \(Fe^{3+}+NO^{2-}+H_{2}O- > Fe^{2+}+H^{+}+NO^{3-}+H_{2}O\)
To balance the redox reaction: \(Fe^{3+}+NO^{2-}+H_{2}O- > Fe^{2+}+H^{+}+NO^{3-}\), we need to ensure that the number of atoms and charges are balanced on both sides of the equation.
First, let's balance the atoms. We have one Fe atom on both sides, so it's already balanced. Next, we have two oxygen atoms on the reactant side (from \(NO^{2-}\) and \(H_{2}O\)) and three on the product side (from \(NO^{3-}\)). To balance oxygen, we can add an \(H_{2}O\) molecule to the reactant side:
\(Fe^{3+}+NO^{2-}+H_{2}O- > Fe^{2+}+H^{+}+NO^{3-}+H_{2}O\)
Now, let's balance the charges. On the reactant side, the total charge is 3+ (from \(Fe^{3+}\) ) + 1- (from \(NO^{2-}\)) = 2+. On the product side, the total charge is 2+ (from \(Fe^{2+}\)) + 1+ (from \(H^{+}\)) + 1- (from \(NO^{3-}\)) = 2+. The charges are already balanced.
Therefore, the balanced redox reaction is:
\(Fe^{3+}+NO^{2-}+H_{2}O- > Fe^{2+}+H^{+}+NO^{3-}+H_{2}O\)
By adding an additional H2O molecule to the reactant side, we balanced both the atoms and charges in the equation.
