hydrogen peroxide (h₂o₂) can be used to lighten or bleach hair. it is produced on an industrial scale by reacting hydrogen (h₂) and oxygen (o₂) gases in the presence of a catalyst. which model accurately represents this reaction? h o

hydrogen peroxide (h₂o₂) can be used to lighten or bleach hair. it is produced on an industrial scale by reacting hydrogen (h₂) and oxygen (o₂) gases in the presence of a catalyst. which model accurately represents this reaction? h o

Answer

Explanation:

Step1: Write the chemical equation

The reaction of hydrogen ($H_2$) and oxygen ($O_2$) to produce hydrogen - peroxide ($H_2O_2$) is $H_2+O_2\xrightarrow{\text{catalyst}}H_2O_2$. In the molecular - model representation, a hydrogen molecule ($H_2$) consists of two hydrogen atoms bonded together ($H - H$), an oxygen molecule ($O_2$) consists of two oxygen atoms bonded together ($O = O$), and a hydrogen - peroxide molecule ($H_2O_2$) has the structure $H - O - O - H$.

Step2: Analyze the models

We need to find the model where a $H - H$ molecule and an $O = O$ molecule react to form a $H - O - O - H$ molecule.

Answer:

The first model (where a molecule with two light - colored spheres representing $H_2$ and a molecule with two dark - colored spheres representing $O_2$ react to form a molecule with two light - colored and two dark - colored spheres in the order $H - O - O - H$) accurately represents the reaction.
