The statement which describes how NO2- reacts in this equilibrium:
<span>H2SO3(aq) + NO2-(aq) HSO3-(aq) + HNO2(aq
is the second option - </span><span>B. as a Brønsted-Lowry base by accepting a proton.
</span>This is because bases take proton H+ in order to become HNO2.

Answer : Option B) as a Brønsted-Lowry base by accepting a proton.

Explanation : In the given reaction H_{2}SO_{3}_{(aq)} + NO_{2}^{-}_{(aq)} ----> HSO_{3}^{-}_{(aq)} + HNO_{2}_{(aq)}

According to the Bronsted-Lowry theory of acids and bases, the formation of conjugate acids and bases forms the central theory.

Wherein, the conjugate base is the ion or molecule which remains after the acid has lost its proton, and the conjugate acid is the species which is created when a base accepts that proton.

In the given question NO_{2}^{-} is the species which is acting as a Bronsted-Lowry base, as this the species which is accepting a proton and getting converted into HNO_{2}.

The number of particles in 1 mole of hydrogen gas is ________.
ivanzaharov [21]
Hidrogen gas is a diatomic gas, this is H2, which means that one molecule of gas has two atoms (every molecule of hydrogen gas consists in H2).

The particles in gases are the molecules, not atoms.

So, every molecule is a particle, and when you are told that you have 1 mole of hygrogen gas means that you have 1 mole of H2 molecules which is the same that 1 mole of particles.

Therefore, the answer is one mole.

Why do different isotopes of an element generally have the same physical and chemical properties?
tresset_1 [31]

Answer:

The correct answer is because they have same number of protons but different number of neutrons.

Explanation:

Isotopes are atoms of the same element but differ only in the number of neutrons in the nucleus, i.e. they have same atomic number but different mass number.

Mass number is affected as they have different number of neutrons, thus effecting their physical properties.

The number of electrons and protons are same, i.e. their atomic number is same and thus their chemical properties are same as chemical properties are determined by the atom’s electronic configuration and that relates to number of protons.
