Which half reaction equation correctly represents a reduction reaction?

a. Li + e- --> Li+

b. Na + e- --> Na+

c. Br2 + 2e- --> 2Br-

d. Cl2 + e- --> 2Cl-

The half-reaction equations that correctly represent a reduction reaction are

c. Br₂ + 2e- --> 2Br-

d. Cl₂ + e- --> 2Cl-

Explanation:

The reduction corresponds to the electron gain of an atom, ion or molecule, that is, it is a reaction in which a substance captures electrons. In other words, there is reduction whenever an atom or group of atoms gains electrons, increasing its negative charges or decreasing the positive ones.   In this way, the oxidation state decreases.

The half-reaction equations that correctly represent a reduction reaction are

c. Br₂ + 2e- --> 2Br-

d. Cl₂ + e- --> 2Cl-

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

explanation:

i think option no d is the correct answer
