Hydrogen peroxide ( H 2 O 2) is an oxidizer commonly used as a bleach. It is a clear liquid, slightly more viscous than water, that appears colorless in dilute solution. It is used as a disinfectant, antiseptic, oxidizer, and in rocket ry as a propellant. The oxidizing capacity of hydrogen

Question:2H2O2 --> O2+2H2O
that's the chemical equation for hydrogen peroxide & manganese dioxide, but i don't know how to create a balanced chemical equation for the reaction of that gas that is produced. please help?
Answers:H2O2 + H2O2 --> O2 + H2O + H2O maybe seeing it like that helps
Question:include links to the source if ppossible!!
Answers:Call your local pharmacy and ask them. They may know
who to call. You can also call your local HAZMET chapter
and ask them.
Question:What is being oxidized in the manganese dioxide and hydrochloric acid reaction?
I am so confused and I'm not sure if I worked out the oxidation states correctly; I got -1 for H in 4HCl
The equation is
MnO2(g) + 4HCl(aq) ----> MnCl2(aq) + 2H2O(l) + Cl2(g) Doesn't Cl go from -4 to 0 since its 4 HCl?
Answers:Mn goes from +4 to +2 ( reduction)
Cl goes from -1 to 0 ( oxidation)
Question:We're doing a titration involving sulfuric acid, potassium permanganate, and hydrogen peroxide. One of the questions is "write the balanced redox reaction". However, first I have to write the balanced chemical equation, but I have no idea how to find the product of the reaction (before splitting into ionic form). From what I hear, this 5H2O2 + 2KMnO4 +4H2SO4 -->2KHSO4 + 2MnSO4 + 5O2 +8H2O
is the balance chemical equation, but I don't understand how the Manganese can split off from the oxygen and attach to sulfate. I also don't understand why sulfuric acid become KHSO4.
Answers:here is the correct equation nett equation
2MnO4- +5H2O2 + 6H+ = 2Mn2++ 5O2 + 8H2O
here are the hal equations
MnO4-(aq) + 8H+(aq) + 5e-==> Mn2+(aq) + 4H2O(l)
H2O2(aq ==> O2(g) +2H+(aq) + 2e-
to get the correct nett equation multiply1 by 2 and 2 by 5 the add
balance the H's on both side .. presto !!
Elephant Toothpaste Experiment using Manganese Dioxide and Hydrogen Peroxide :This is my M5A Chemistry class doing an experiment using Manganese Dioxide (which is a really black powder), 30% hydrogen peroxide, liquid dishwashing soap, and some drops of green food coloring to produce the world famous elephant toothpaste (large snake version).
Hydrogen Peroxide Foam :Student comparing the reaction of a test tube containing hydrogen peroxide by itself, to a test tube which has hydrogen peroxide and a catalyst added (manganese dioxide). Foam has been created by the dishwashing liquid in the bottom to collect the liberated oxygen gas.
