What is oxidized in an electolytic cell with aluminum and gold electrodes?
In an electrolytic cell with aluminum and gold electrodes, aluminum would be oxidized at the anode. This is because aluminum has a higher tendency to lose electrons compared to gold, making it more likely to undergo oxidation.
What effect does vinegar have on aluminum?
Vinegar can cause aluminum to corrode or oxidize, leading to the formation of a dull, rough surface on the metal.
Why do coins oxidize?
Coins oxidize when exposed to oxygen in the air, leading to the formation of a layer of oxidation on their surface. This oxidation is typically seen as a greenish color, known as patina, which is caused by the reaction of the metal in the coin with oxygen and moisture in the air. The presence of copper in many coins makes them particularly prone to oxidation.
How does blood oxidize and what factors contribute to this process?
Blood oxidizes when oxygen molecules in the blood react with other molecules, such as iron in hemoglobin, forming compounds like oxyhemoglobin. Factors that contribute to this process include the presence of oxygen, temperature, pH levels, and the presence of certain enzymes in the blood.
How many atoms of oxygen are there in one unit of aluminum?
Well, aluminum is an element, so none. However, aluminum does oxidize, and some quantity of oxygen might be derived if you will provide the surface area of the aluminum being oxidized, and the conditions, which would estimate a rate of oxidation without actually giving you any meaningful number. Aluminum oxide--the oxidate on the surface of oxidized aluminum--is Al2O3, or 2 parts Al to 3 parts O.

Is oxidize a chemical or phyisical change?
oxidation is a chemical change
Why does a new aluminum pan become dull if it sits in a cupboard?
Exposure to air and moisture can cause aluminum to oxidize, forming a dull layer on the surface of the pan over time. This oxidation process is normal and can be removed by cleaning the pan with a mixture of vinegar and water or a specialized aluminum cleaner.
What elements or compounds can oxidize molecular Oxygen?
Substances which can oxidize molecular Oxygen(O2) are =Fluorine(F2) - It will oxidize Oxygen to +2 oxidation state:F2 + O2 ----> OF2 (Oxygen difluoride)Platinum(VI) Fluoride - It will oxidize Oxygen to +1/2 Oxidation state:O2 + PtF6 ----> O2PtF6 (Dioxygenyl Hexafluoroplatinate)
How many years does it take for a aluminum to decompose?
It never does, aluminium is an element That could possibly be false. Aluminium doesn't decompose because it is a element, however it does oxidize. So if the question is how long will it take to all oxidize the answer is that it won't because the first layer of oxide will form a shield stopping oxidation. Summary: any amount larger than a few microns will never completely oxidize, unless persuaded. (Only if the aluminum is very finely divided - powdered - will it oxidize in air.)
Why iron corrodes but aluminum does not?
Both iron and aluminum will oxidize. When iron oxidizes the product (rust) easily crumbles away, exposing more iron to oxidation. Aluminum is even more reactive than iron, but the aluminum oxide that forms is one of the hardest known substances and forms a protective layer that, even though it is microscopic, shields the aluminum from corrosion.
What effect does vinegar have on aluminum?
Vinegar can cause aluminum to corrode or oxidize, leading to the formation of a dull, rough surface on the metal.

What metal rusts by oxidation?
Many metals will oxidize but only Iron forms rust when doing so.
Why fluorine cannot be prepared by oxidation of fluoride ion?
Fluorine is so electronegative that there isn't really anything that can oxidize it.
Does aluminum oxide rust?
Yes. In fact, aluminum oxidizes faster than almost any other metal, which is why aluminum foil will, actually, remove rust: The abrasion removes the coating of aluminum oxide that covers all metallic aluminum exposed to the air, and the exposed aluminum metal wants to be oxidized so badly that it will actually steal oxygen from iron oxide, AKA rust, and reduce it back to iron metal. Which is why aluminum foil will, in fact, remove rust. This reaction, interestingly, is the same one that makes thermite work.
