Potassium Superoxide (KO₂) Can Simulate a Plant-Type Action by Consuming

Multiple Choice

Potassium superoxide (KO₂) can simulate a plant-type action by consuming carbon dioxide (CO₂) gas and releasing oxygen (O₂) gas. The other product is potassium carbonate (K₂CO₃) . When the equation for this process is balanced, it shows that:

A) 3 mol oxygen is produced per mol KO₂ consumed
B) 2 mol KO₂ is consumed per mol carbon dioxide
C) moles of reactants equals moles of product
D) 3 g of oxygen is produced per 2 g CO₂ consumed
E) moles of products exceed moles of reactants
