An oxidation-reduction reaction involves the
(1) sharing of electrons
(2) sharing of protons
(3) transfer of electrons
(4) transfer of protons

The best answer is (3)

In these kind of reactions, there is a transfer of electrons from one reactant to another. electrons are lost from one substance and gained by another.

Oxidation is loss of electrons from a substance, and Reduction is gain of electrons  by a substance.

These two processes cannot occur without the other. If there is a reduction there must be an oxidation reaction and vice versa. The reactions  usually occur simultaneously.

For example, table salt is formed by a redox reaction. Sodium is oxidized i.e. loses an electron (and becomes positively charged) while chlorine gas is reduced i.e. gains the electron (and become negatively charged). The result is formation of sodium chloride.

2b2t

explanation:

2b2t

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
