None of the given options are correct, and the correct answer is 174 K.
<u>Explanation:</u>
Mass of N = 41.6 g
Moles =
= = 1.5 moles
Pressure, P = 815 mm Hg = 1.07 atm
Volume, V = 20 L
R = gas constant = 0.08205 L atm mol⁻¹ K⁻¹
Temperature, T = ? K
We have to use the ideal gas equation,
PV = nRT
by rearranging the equation, so that the equation becomes,
T =
Plugin the above values, we will get,
T =
= 174 K
So the temperature of the nitrogen gas is 174 K.
When nitrous acid (HNO₂) dissociates in water (H₂O), the reaction that best captures this process is:
HNO₂ (aq.) + H₂O ↔ H₃O⁺ (aq.) + NO₂⁻ (aq.)
How does one know about HNO₂?
- The chemical designation for nitrous acid is HNO₂, and it is a monoprotic acid. Three elements—hydrogen(H), oxygen(O), and nitrogen(N), all compose it.
- It is highly fragile in nature and only occurs in solutions.
- It is employed to convert amines into diazonium salts.
Is HNO₂ a basic or an acid?
Acidity is assigned to nitrous acid (HNO₂). Once dissolved in water, it gives out H+ ions. Acid is a chemical that produces H+ ions in a water-based solution or gives the protons to other molecules.
Thus, HNO₂ is acid because it causes a mixture of water to contain H+ ions. In a 10 mM concentration, it possesses a pH of 2.67.
