In the equation below, identify the Brønsted-Lowry acid, Brønsted-Lowry base, conjugate acid, conjugate base.

NH4+(aq) + NO-2 (aq) = HNO2(aq) +NH3(aq)

HNO₂ is Bronsted- Lowery conjugate acid.

NH₃ is Bronsted- Lowery conjugate base.

NH₄⁺(aq)  is  Bronsted- Lowery acid.

NO₂⁻²is  Bronsted- Lowery base.

Explanation:

Bronsted- Lowery acid:

Bronsted- lowery acid is the specie which have capability to donate the proton.

Bronsted- Lowery conjugate base:

The Bronsted- Lowery conjugate base of Bronsted- Lowery acid is the specie which is formed after when an acid donate the proton.

Bronsted- Lowery base:

Bronsted- lowery base is the specie which have capability to accept the proton.

Bronsted- Lowery conjugate acid:

The Bronsted- Lowery conjugate acid of Bronsted- Lowery base is the specie which is formed after when an base accept the proton.

Chemical equation:

NH₄⁺(aq) + NO₂⁻²(aq) → HNO₂(aq) + NH₃(aq)

NH₄⁺(aq)  have an extra proton and can donate it so it is Bronsted- Lowery acid.

NO₂⁻² have negative charge and can accept the proton so it is  Bronsted- Lowery base.

HNO₂ is Bronsted- Lowery conjugate acid.

NH₃ is Bronsted- Lowery conjugate base.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
