How quickly does stainless steel rust?
Stainless steel is resistant to rust, but it can still rust over time if not properly maintained. The rate at which stainless steel rusts depends on factors such as the grade of stainless steel, environmental conditions, and maintenance practices. In general, stainless steel rusts at a slower rate compared to other types of steel.
Is oxygen more reactive than copper?
Yes, oxygen is more reactive than copper. Oxygen can readily react with many materials, including metals like copper, to form oxides. This is why copper often forms a tarnished or oxidized surface when exposed to air.
Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
Why does hydrogen peroxide make rust orange?
Hydrogen peroxide reacts with the iron oxide (rust) on the surface of the metal, breaking it down into its chemical components. This reaction forms a hydrated iron oxide, which is typically orange in color.
Explain why you would not exspect to be able to combine magnesium and argon to produce a useful substance?
Magnesium is a highly reactive metal that easily loses electrons to form compounds, whereas argon is an inert gas that does not readily react with other elements. Because of this stark difference in reactivity, it is unlikely for magnesium and argon to form a stable compound when combined.
