The rusting of metal is an example of what change?
Is an example of chemical change, reacting to air
Why rusting is a chemical change and not a physical change?
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
Is copper when it turns green in the air a chemical change?
The green color on copper when it oxidizes in the air is a physical change, not a chemical change. The process is primarily due to the formation of a layer of copper oxide on the surface of the copper, which alters the appearance without changing the chemical composition of the copper itself.
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).
Copper turns a greenish color is it chemical or physical change?
The color change of copper to green is a chemical change. This is due to the formation of a green patina on the surface of the copper, typically caused by oxidation reactions with the air and moisture.
Is copper metal turning green on exposure to air and water a physical or chemical change?
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
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 copper turning green when expose to environment a chemical change and why?
Yes, the green patina that forms on copper is a chemical change called oxidation. When copper reacts with oxygen and moisture in the air, it forms copper oxide and then copper carbonate, creating the green color seen on aged copper surfaces.
Is reacting to air chemical or physical property?
This is a chemical property.
How is letting a copper kettle tarnish a chemical change?
Letting a copper kettle tarnish is a chemical change because it involves a reaction between the surface of the copper and elements in the air, like oxygen and sulfur compounds, forming new compounds like copper oxide or copper sulfide on the surface. This chemical reaction alters the composition of the copper material, leading to a permanent change in its appearance.
Is reacting to air a physical or chemical property?
Reacting to air is a chemical property because it involves a change in the chemical composition of the substance when it comes into contact with oxygen in the air, leading to the formation of new compounds. It reflects how a substance interacts with its environment on a molecular level.
When copper turns green when exposed to air a physical or chemical change?
When copper turns green upon exposure to air, it undergoes a chemical change. This process occurs due to the reaction of copper with oxygen and moisture in the environment, forming copper carbonate and other compounds, commonly referred to as patina. Unlike physical changes, which do not alter the substance's chemical identity, this transformation changes the composition of the material.
