Final answer:
The subject of this question is Chemistry and it is at the High School level. The chemical reaction described involves the reaction between potassium superoxide and carbon dioxide to form potassium carbonate and oxygen.
Step-by-step explanation:
The subject of this question is Chemistry.
The grade level of this question is High School.
The chemical reaction described in the question is a reaction between potassium superoxide (KO2) and carbon dioxide (CO2) to form potassium carbonate (K2CO3) and oxygen (O2).
The balanced chemical equation for this reaction is: 4 KO2(s) + 2 CO2(g) → 2 K2CO3(s) + 3 O2(g)
