It has been given that,
NO + Ag⁺ → NO₃⁻ + Ag
The oxidation half reaction is,
NO + Ag⁺ = NO₃⁻ + Ag
The reduction half reaction is,
Ag⁺ +e⁻ → Ag
The overall balanced reaction is:
3Ag⁺ + NO + 2H₂O → 3Ag + NO₃⁻

Answer:
The pressure of the flask is 0.73 atm.
Explanation:
To solve this question, we should use the ideal gas law: PV=nRT, where P represents the pressure (in atm in this case), V represents the volume (in L), n represents the number of moles of gas, R is the ideal gas constant, and T represents the temperature (in K).
Before we can plug our values into the equation, we must convert so that our units cancel out. First, we should convert our temperature from degrees Celsius to degrees K.
25°C + 273.15 = 298.15K
Next, we should convert the 0.12 g He to moles using the molar mass of He.
0.12 g He * (1 mole He/4.003 g He) = 0.029978 mol He
Now, we can plug in the values into the equation and solve for the pressure.
PV = nRT
P = (nRT)/V
P = (0.029978 mol He * 0.0821 L*atm/mol*K * 298.15 K)/(1.0 L)
P = 0.73 atm
Therefore, the correct answer is 0.73 atm.
Hope this helps!
D. Oversaturated is the answer to this question
The correct option is D.
Alchemists are early chemical scientists, who first delved into the subject of chemistry. These early scientists were able to study the characteristics of common elements, the features of compounds and some of the laboratory methods that they developed then were found useful by later scientists. One thing that alchemists are known for is their quest to turn lead into gold.
