Oxygen can be prepared by decomposition of Hydrogen peroxide(H2O2), catalyzed by Manganese dioxide(MnO2).
2 H2O2 ---MnO2---> 2 H2O + O2
In addition, electrolysis of water will also produce oxygen at one electrode and hydrogen at the other electrode.
There are a few different methods that are used to prepare oxygen for different purposes. To prepare oxygen you can pressurize it, heat it, or mix it with other substances such as trace amounts of carbon to stabilize it.
Making pure atmospheric gases is fairly easy if you've got the right equipment. It works because when you compress air it heats up because the molecules in it are excited, and when you decompress air it cools down. If you were to take the heated compressed air and cool it before you decompress it, the decompression cooling will drop the temperature of the gas below its condensation point. The process is as follows: compress air.
cool the compressed air. Decompressing air reduces its temperature by a known amount, so they cool the air to the point where decompressing it will lower its temperature to -183C, the condensation temperature of oxygen. Some plants require several compress-decompress cycles to get the gas cold enough to condense.
collect the condensed oxygen and store it in a Dewar flask.
At this point you've got liquid oxygen. This is a very useful product on its own--concentrated liquid oxygen is more cost-effective to transport than is gaseous oxygen, so if they need to move it from the gasification plant to a dealer's warehouse, that's how they move it. It's good for military applications too--they put a small tank of it in fighter planes, heat it up and supply the oxygen to the pilot for breathing. Some hospitals get it this way too--they can heat it up for patients to breathe, and store a lot more oxygen in liquid form than they could ever store as compressed gas. When they've removed oxygen from the air, they have a gas mixture with other valuable gases, like nitrogen, and to recover them they just continue the compress/cool/decompress cycle until all the valuable gases have been removed.
Oxygen can be prepared in the laboratory by red mercuric oxide, or by heating Potassium Chlorate in a test tube in the presence of Maganesedioxide.
Fit a test tube with a delivery tube and place the delivery tube under a gas jar filled with water and placed on beehive shelve in a water tub. Heat the test tube containing Potassium Chlorate and Maganesedioxide. The oxygen produced in this reaction is passing through the delivery tube to the gas jar by the downward displacement of water.
Electrolysis of water will produce oxygen in the lab. It does need a trace of acid to help. Another common way is to heat a chlorate salt such as potassium chlorate.
2KClO3 ----> 2KCl + 3O2
Oxygen is not made - it is present naturally in the earths atmosphere. It is PRODUCED industrially by fractionation of liquid air
One of the laboratory prepare preparation of oxygen is by thermal dissociation of tetraoxochlorate V
Animals obtain oxygen by breathing.
It is made by reacting it with carbon dioxide it forms sodium carbonate and oxygen. This makes it useful in scrubbing carbon dioxide and producing oxygen in submarines.
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
Nothing! Because oxygen is a chemical!!!! -------- Oxygen can be prepared by separation from air or by water electrolysis; preparation from HgO and other chemicals are now obsolete.
Chlorine gas is commercially prepared by electrolysis of aquaeous sodium chloride.
they are different isotopes of oxygen, oxygen-17 has one more neutron than oxygen-16 making it slightly heavier. Oxygen-17 will react slightly slower than oxygen-16 since it has more mass.
Oxygen can be prepared by the electrolysis of water. 2H2O + electricity --> 2H2 + O2
Ozone is prepared in laboratories by a chemical process. When oxygen is treated with UV radiations oxygen gets converted into ozone.
Pure oxygen gas can be prepared in the laboratory by the decomposition of solid potassium chlorate to form solid potassium chloride and oxygen gas. 34.0 g
It's too costly to prepare oxygen in lab to be commercially successful.
It is made by reacting it with carbon dioxide it forms sodium carbonate and oxygen. This makes it useful in scrubbing carbon dioxide and producing oxygen in submarines.
Thioglycollate medium is correctly prepared when a red/brown color appears at the top of the broth. This is beacuse of the Reazurin which is reactive to oxygen.
yes KClO3 + heat --> KCl + O2
steel prepared by the mixing of pig iron,scrap iron,heamatite in the presence of oxygen
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
ozone can be prepared from oxygen by by passing electric discharge through oxygen gas. it is necessory to use silent discharge because sparking would generate heat energy which decomposes ozone produced. the apparatus used for converting oxygen into ozone is known as ozonizer.
i work at a transmission shop i see these all the time it is an oxygen sensor. they can be expensive so be prepared
Phosphite ion consists of Phosphorus and Oxygen as PO33- and hydrogen phosphites (HPO32-) and dihydrogen-phosphites (H2PO3-) consist of phosphorus, oxygen and Hydrogen. Phosphite salts are generally prepared from Phosphorous Acid (H3PO3)
