Is iron tendency to rust when exposed is exposed to oxygen and water chemical change?
First of all rust is formed when iron is exposed to both oxygen and water/ water vapopurs. The formula for rust is Fe203.xH20. Now the x varies which determines the extent to which rust is formed. Basically Rust is formed throughout the surface of the iron thus preventing rusting of the inner layers.

Is tendency to rust a chemical change or a physical change?
Rusting is a chemical change because of the reaction between certain chemicals, whereas in a physical change, some thing is growing or physically change, like a baby.Another physical change is phase change (from solid to liquid when melting).The tendency to rust is not a change, it is a property.its chemical.
When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.
Is forming ozone from oxygen a chemical change?
Putting oxygen in tanks (under pressure) is a physical change, not a chemical change. The chemical nature of the oxygen has not been altered, and it is possible to recover the original substance, thus it is not a chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.

Is the tendency of iron to rust physical or chemical?
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
What chemical change takes place when steel is exposed to water?
Corrosion occur if oxygen exist also.
Is a silver teapot turning black a chemical or physical change?
It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
Is sodium turning black when exposed to air a chemical change?
the answer is yes because sodium is a solid right right so being exposed by a chemical is changed.
Is white phosphorus that glows when exposed to air a chemical change or a physical change?
White phosphorus is a very reactive chemical because of its structure. When it is heated some, it can react with oxygen to create phosphorus pentoxide (it is in this exothermic reaction that you see the glow). So it is indeed a chemical change.
What element turns into rust after a chemical change?
Iron. Iron, when exposed to oxygen, turns into iron oxide - better known as rust.
When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.

Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
What chemical is rust?
Iron and water exposed to oxygen Ferrous oxide
