Consider the reaction below. Which species is(are) the Brønsted-Lowry acid(s)? HF (aq) + NHâ (aq) â NHâ⺠(aq) + Fâ» (aq) g

HF is the acid

Explanation:

The Brønsted-Lowry theory defines the acids and bases in chemistry as follows:

An acid is the species that can donate a proton

A base can accept protons.

In the reaction:

HF(aq) + NH₃(aq) → NH₄⁺(aq) + F⁻(aq)

As you can see, HF can donate its proton to produce F⁻: HF is the acid

In the same way, NH₃ is accepting a proton, NH₃ is the base.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
