Explain with a well-labelled diagram the preparation of oxygen
Answers
Answer:
producing oxygen
Hydrogen peroxide, which slowly breaks down into water and oxygen, can be used to create oxygen:
oxygen and water form hydrogen peroxide.
O2 = 2H2O(l) + 2H2O2(aq) (g)
Manganese(IV) oxide is a catalyst that can speed up a reaction.
Bubbles of oxygen are released when hydrogen peroxide is combined with manganese(IV) oxide.
apparatus set up to gauge the gas volume in a process.
Gas from the reaction mixture exits a flask through a pipe at the top and descends into a water trough.
The water then bubbles up through a honeycomb shelf and into an upside-down glass jar.
Gas builds up at the jar's top, pushing water into the trough below as a result.

Explanation:
There are a lot of laboratory processes for producing oxygen. but one of the best processes is simply treating hydrogen peroxide in a particular manner. Oxygen can be made from hydrogen peroxide, which decomposes slowly to form water and oxygen:
hydrogen peroxide → water + oxygen
2H2O2(aq) → 2H2O(l) + O2(g)
The rate of reaction can be increased using a catalyst, manganese(IV) oxide. When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off.
To make oxygen in a laboratory, hydrogen peroxide is poured into a container (conical flask) containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. As the oxygen collects in the top of the gas jar, it pushes the water out.
This gas collecting container (conical flask) can also be substituted with a gas syringe to collect the oxygen produced by this method.
