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 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 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 A bronze statue develops a green coating (patina) over time is physical change or chemical?
It is chemical. The copper in bronze turns green when it oxidizes.
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 turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.

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 turing green a physical or chemical change?
It's a chemical change. Copper oxidizes to form copper oxide, which is similar to iron rusting. A color change very often indicates a chemical change.
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.
By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
Is the Statue of Liberty a physical change or a chemical change?
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
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.

It is chemical. The copper in bronze turns green when it oxidizes.
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.
If copper metal rusts would it be a physical change?
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
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.
