Question

Baker’s yeast catalyzes the decomposition of hydrogen peroxide (dihydrogen dioxide) into oxygen and water.  Directions: Add 10 mL of hydrogen peroxide to an Erlenmeyer flask.  Add a few grains of yeast and watch the reaction.

hydrogen peroxide- H2O2

yeast-?

please write the unbalanced and balanced chemical equation

Answer 1

Unbalanced Chemical Reaction:

H₂O₂ $\rightarrow$ H₂O + O₂

Balanced equation:

We have:

H₂O₂ $\rightarrow$ H₂O + O₂

First, we balance the number of O atoms by multiplying the coefficient of O with 0.5. We have:

H₂O₂ $\rightarrow$ H₂O + 0.5 O₂

Since the coefficients of Equations always need to be whole numbers, we multiply throughout with 2.

We get:

2 H₂O₂ $\rightarrow$ 2 H₂O + O₂

This is the balanced equation
