Which species is the oxidizing agent in the following equation? Hint: the oxidizing agent accepts the electrons in an electron transfer reaction.
K + O2 ---> KO2

a. K

b. O2

c. KO2

d. This is not an oxidation-reduction reaction

acts as oxidizing agent.

Explanation:

Oxidation reaction : When there is an increase in oxidation state number.

Reduction reaction : when there is a decrease in oxidation state number.

Potassium metal has undergone oxidation, as its oxidation state is changing from 0 to +1. Potassium metal is getting converted into potassium ions.

Oxygen has undergone reduction, as its oxidation state is changing from 0 to -1.

The chemical agent which itself get oxidized and reduce others is called reducing agent and the chemical agent which itself get reduced and oxidizes others is called oxidising agent. Thus acts as oxidizing agent.

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.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
