**Educational Content: Chemistry****Topic: Chemical Reactions and Stoichiometry****Example Problem: Decomposition of Hydrogen Peroxide***Problem Statement:*Bombardier beetles inject boiling hydrogen peroxide, or \( H_2O_2 \), into their victims. It then decomposes into hydrogen and oxygen gas. How many molecules of oxygen can be produced if 4.10 moles of hydrogen peroxide are decomposed?*Solution:*First, we need to understand the decomposition reaction of hydrogen peroxide. The balanced chemical equation for the decomposition of hydrogen peroxide is:\[ 2H_2O_2 \rightarrow 2H_2O + O_2 \]This equation tells us that 2 moles of \( H_2O_2 \) decomposes to produce 1 mole of \( O_2 \).1. Find the number of moles of \( O_2 \) produced from 4.10 moles of \( H_2O_2 \): \[ \frac{1 \text{ mole } O_2}{2 \text{ moles } H_2O_2} \times 4.10 \text{ moles } H_2O_2 = \frac{4.10}{2} \text{ moles } O_2 = 2.05 \text{ moles } O_2 \]2. Convert moles of \( O_2 \) to molecules of \( O_2 \) using Avogadro's number (\( 6.022 \times 10^{23} \text{ molecules/mole} \)): \[ 2.05 \text{ moles } O_2 \times 6.022 \times 10^{23} \text{ molecules/mole} = 1.23451 \times 10^{24} \text{ molecules} \]Therefore, 4.10 moles of hydrogen peroxide can produce approximately \( 1.23 \times 10^{24} \) molecules of oxygen.

The number of moles is the mass-to-molar mass ratio. It is represented by n. The formula of the…
