What chemical reaction is your team doing? |
A Exothermic Reaction because the foam produced is hot. When hydrogen peroxide is combined with the yeast catalyst, it produces a chemical reaction in form of a foaming substance. |
|
|
Which is the catalyst? |
Yeast |
|
|
What is the balanced chemical equation for the reaction? |
2H2O2 → 2H2O(l) + O |
|
|
What are the names of the reactants in the chemical equation? |
*hydrogen peroxide *potassium iodide *dish soap *yeast. *2H2O2 *reactant: the substance that undergoes a change during a chemical reaction. |
|
|
What are the names of the products in the chemical equation? |
*Hydrogen peroxide *dry yeast which serves as the catalyst, *liquid dish soap *food coloring *warm water. *2H2O(l) + O |

How might you experience this chemical reaction in everyday life? Is it a useful reaction? Are there any negative aspects or problems with the reaction (pollutants released, etc.) |
*The burning of sugar *It’s a useful reactions because it is involved in baking to create substances that are edible *can also be harmful in the way that it can destroy environments without too much heat production, such as nuclear fissions (they also produce radiation, which is extremely harmful) *Examples of decomposition in everyday life includes anything that can be broken down into smaller pieces, such as bites of food |
|
|
What are the steps? |
1)Pour hydrogen peroxide into the bottle 2) add food coloring 3)add dish soap and then mix the bottle around to mix 2 reactants 4)In another cup we will pour warm water and the yeast 5) take the mixture and pour it into the soap and HP mixture. |
