|We have learned this week about chemical reactions, mostly on paper.
Let’s try to see some of those reactions happening.
For this discussion board we will share videos of experiments/demonstrations in which chemical reactions are performed and we will explain the reaction happening.

b. The overall equation for this reaction is:
2 H2O2(aq) → 2 H2O(l) + O2(g)
The decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion.
30% hydrogen peroxide (H2O2)
When hydrogen peroxide (H2O2) decomposes, it breaks down to form water (H2O) and oxygen (O2). Sodium iodide acts as a catalyst speeding up the decomposition of hydrogen peroxide. The soap bubbles that erupt from the container are filled with oxygen. As the reaction takes place, steam rises from the erupting foam. This shows that the reaction is exothermic, meaning that it gives off heat.
