WebIt’s chemical formula is H2O2, so every molecule has two hydrogen atoms and two oxygen atoms. This is super close to H2O, or water! When hydrogen peroxide breaks down, it turns into oxygen (O2)) and water … WebOption 1: Sierra is doing a lab to make elephant toothpaste. She can see from the lab that hydrogen peroxide (H 2 O 2) is reacting to form water and oxygen. Write a balanced equation for this reaction. If she measures 140g of starting solution and it is 40% hydrogen peroxide by mass, how many grams of hydrogen peroxide does she start out with?
Why does elephant toothpaste work?
WebThe proposed mechanism is as follows: H 2 O 2 (aq) + I - (aq) → IO - (aq) + H 2 O (l) H 2 O 2 (aq) + IO - (aq) → I - (aq) + O 2 (g) + H 2 O (l) The first step is believed to be the rate determining (slow) step. Recall that catalysts work by proceeding along a different reaction pathway of lower activation energy. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide (H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. Because it requires only a small number of ingredients and makes a "volcano … tripuso display solutions
