Answer the following question based on the previously determined balanced chemical equation (H2O2--> 2H2O + O2)

Question

Answer the following question based on the previously determined balanced chemical equation for the decomposition of hydrogen peroxide. Express your answer to two decimal places.

How many moles of H₂O₂ are needed to produce 21.55 moles of O₂?

Answer 1

Balance equation:

2H2O2 → 2H2O + O2

21.55 mole O2 x (2 mol H2O2/1 mol O2) = 43.10 mol H2O2
