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.

b)the final kilocalories per gram for food will be less since

c) the final kilocalories per gram for food will be less since the reaction will eventually go to completion

d) the final kilocalories per gram for food will be more.

Explanation:

a) the final kilocalories per gram for food will be less because the mass was reduced from 110.3 to 101.3g

b)the final kilocalories per gram for food will be less since some marshmallow fell off before the reaction

c) the final kilocalories per gram for food will be less since the reaction will eventually go to completion

d) the final kilocalories per gram for food will be more since the thermometer that got stuck will add to the value of final kilocalories per gram

Naddik [55]

The amount of substance present in a certain object with a given half-life in terms of h can be expressed through the equation,

A(t) = (A(o))(0.5)^(t/h)

where A(t) is the amount of substance after t years and A(o) is the original amount. In this item we are given that A(t)/A(o) is equal to 0.89. Substituting the known values,

0.89 = (0.5)(t / 5730 years)

The value of t from the equation is 963.34 years.
