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.

Answer:
110.7 kpa or 1.097 atm your choice of pressure units
Explanation:
We can assume the Volume is constant since we are not told other wise and it is indeed a car. We can Use P1/T1= P2/T2
So (T2xP1 )/ T1 = P2
(318Kx101.3kpa)/291k = 110.7 kpa or 1.097 atm your choice of pressure units
if your wondering why i used Kelvin gas laws are always in units of Kelvin
Answer:
Mass = 0.6 g
Explanation:
Given data:
Moles of NaOH = 0.015 mol
Mass of NaOH = ?
Solution:
Number of moles = mass/ molar mass
by rearranging this formula,
Mass = number of moles × molar mass
Molar mass of NaOH is 40 g/mol
by putting values,
Mass = 0.015 mol × 40 g/mol
Mass = 0.6 g
Answer:
C. 64
Explanation:
Given:
The number of equally likely sample outcomes of a single stage = 4
Unknown:
Total number of elements if there are three stages= ?
Solution;
Probability is the likelihood of an event to occur.
In this problem;
For a single stage, the likely outcome is 4
So therefore;
For the 3 stages 4 x 4 x 4 = 64
Therefore, the total number of elements in the sample space of an experiment with 3 stages is 64
Answer: C. Quart
Explanation:
Quart is a unit of measurement for liquids and is equivalent to 2 pints.
