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.

Traveling at the speed of light - how long would it take, in years, to reach the top of the pile of balls? Show all calculations

marusya05 [52]

The time taken for the object to reach to top of pile is 0.012 year.

<h3>Time of motion </h3>

The time taken for the object to reach to top of pile is calculated as follows;

time of motion = distance traveled/speed

time of motion = (1.1 x 10¹⁴ x 10³ m)/(3 x 10⁸ m/s)

where;

speed of light = 3 x 10⁸ m/s

time of motion = 3.67 x 10⁵ sec = 0.012 year

Thus, the time taken for the object to reach to top of pile is 0.012 year.

What principle requires that a chemical equation be balanced?

Dafna1 [17]

The principle that requires that a chemical equation be balanced would be the law of definite proportions. It states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation. Hope this answers the question.
