Balance the following redox reaction in basic solution. cl ⒠(aq) + mno ⒠4 (aq) → cl 2 (g) + mno 2 (s)

Three molecules contain six chlorine atoms. Three would thus correspond to six ions.

Combining six , two ions, three ions, and two would balance the changes in oxidation state.

(NOT BALANCED)

Still, the product side lacks four oxygen atoms.

Each oxygen atom combine with a water molecule to produce two hydroxide ions. Adding four water molecules and eight hydroxide ions would balance the equation.

answer: mercury

explanation:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
