Oxygen.
Steel is more dense than oxygen. The density of steel is about 7.87 grams per cubic centimeter, whereas the density of oxygen is about 0.0013 grams per cubic centimeter.
Oxygen is the only gas which rust the metals.
Water is H2O. Hydrogen peroxide is H2O2. Hydrogen peroxide has one more oxygen atom per molecule than water. The extra oxygen is what makes it a peroxide. "Hydrogen oxide" would be water. The extra oxygen also makes hydrogen peroxide much more reactive than water due to the unstable oxygen-oxygen bond.
Steel wool corrodes in water because it contains dissolved oxygen and other electrolytes that can react with the iron in the steel wool, causing oxidation. In contrast, orange juice is acidic and contains citric acid, which can act as a protective barrier by passivating the iron surface and preventing corrosion.
No. There is more oxygen in deeper water.
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
Rusting is the result of oxidation of iron (steel). Theer's more dissolved oxygen in shallow water than there is in deep water.
A steel is considered to be stainless if it contains 13% or more chromium.
Freshwater has more oxygen than salt water but oxygen is more solublein fresh water.
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.
It makes US produced steel cheaper in the international market. Also it makes oil more expensive which in turn makes foreign steel more expensive in transportation cost. Therefore US steel industries will benefit as a whole.
The amount of oxygen disolved in water may vary. The capacity of water to absorb oxygen (which is not necessarily how much is actually absorbed) depends mainly on the temperature. I don't think the water being salty makes much of a difference.
