Why can't the formation of carbon monoxide and aluminium oxide cannot be determined directly by experimental means?
carbon monoxide is readily oxidized to carbon dioxide and and aluminium oxide coats al forming an inert layer preventing further reaction.
What is nature of the oxide formed by aluminum?
Aluminium forms the oxide Al2O3, often called alumina or corundum. It is a hard substance. Chemically it is classed as amphoteric because it reacts with acids and bases. It forms on the surface of aluminium very rapidly and passivates the surface. Aluminium is actually a reactive metal but because ot the invisible, thin oxide layer appears quite inert; without the layer aluminium would react with water to generate hydrogen.
How can a layer of aluminum oxide be made thicker and what is the process called?
The layer can 't thickned further because Al2O3 aluminium oxide or in other words corrosion. IT is the tendency of aluminium that the layer of aluminium oxide(white in colour) or corrosion prevents the metal from further corrosion.So only one layer of aluminium oxide can be on the meatal it cant be thickned.
Why is the magnesium strip polished before weighing?
To remove the oxide layer (magnesium oxide) on it
How do some reactive metals avoid serious corrosion damage?
Some reactive metals avoid complete corrosion by the formation of a stable oxide on their surface. Oxygen oxidizes the metal on the surface of the metal, forming a metal oxide. In some cases, this oxide does not easily separate from the rest of the metal, and is inert under the conditions present. In this case, the rest of the metal avoids corrosion, as oxygen cannot penetrate through the oxide layer to react further.

Is titanium oxide highly reactive?
no it is inert and used as pigments for white paints ....

What is pilling bedworth rule?
According to Pilling-Bedworth rule, if the volume of oxide layer formed is greater than the volume of the metal, the oxide layer is protective and non-porous. However if the oxide layer formed has volume lesser than that of the underlying metal then the oxide layer is porous and non-protective.
What are the differences in the properties between the silicon substrate and the oxide layer?
Silicon Substrate Silicon substrates are mainly used for power semiconductors in automotive, electronics and HF front-end pa. silicon that can be fused with other materials, such as thermal oxide and or silicon nitrite. Oxide Layer An oxide layer is a thin layer or coating of an oxide, such as iron oxide. Such a coating may be protective, decorative or functional. It is a passivizing layer on the surface of the metal, preventing further corrosion.

How does iron oxide harm the environment?
Because the oxide hits the ozone layer and I think that is why

What chemical attacks the ozone layer?
CFCs, nitrous oxide.
What are the dangers in the ozone layer of the stratosphere?
Freons + Nitric Oxide are a danger to the ozone layer in the stratosphere.
Are there any known helium compounds?
No. It"s an inert gas,inert gases do not form compounds. Reactive gases(like Hydrogen ) do, like H-2-O or Hydrogen-Di-Oxide-better known as water.
