Question

which of the following is a decomposition reaction​

Answer 1

Ur question is incomplete dude.

My greatest achievement in life so far is learning how to accept my failures. It is my motivation. It makes me stouter, wiser in choosing actions that I shall take, and strive more to do better in my next steps in life. ... My failure made me feel that I'm not smart enough and I'm not capable of doing things around me.

Answer 2

Answer:

Hydrogen peroxide is a widely used disinfectant for minor cuts and scrapes. You may have a bottle of hydrogen peroxide like the one pictured here in your medicine cabinet at home. Did you ever notice that hydrogen peroxide is always kept in a dark brown bottle like this one? Do you know why? The reason is that hydrogen peroxide needs to be protected from light. If it isn’t, it will gradually break down to water and oxygen. This is a decomposition reaction.  

Explanation:

What Is A Decomposition Reaction?

A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation:

AB → A + B

In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction. The arrow shows the direction in which the reaction occurs.

Q: What is the chemical equation for the decomposition of hydrogen peroxide (H2O2) to water (H2O) and oxygen (O2)?

A: The equation for this decomposition reaction is:

2 H2O2 → 2 H2O + O2
