It is a chemical change because chemical reactions are involved; copper become hydrated copper carbonate.
Chemical.
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
Copper turns green due to a chemical reaction with oxygen and other elements in the environment, forming a layer of copper oxide and copper carbonate on the surface. This process is known as oxidation and is a chemical change.
It is chemical. The copper in bronze turns green when it oxidizes.
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.
It is a chemical change.
Chemical.
Chemical because it is being exposed to another compound and forming a new substance
Examples of solids in a chemical change include baking soda (sodium bicarbonate) turning into carbon dioxide gas and solid copper turning into copper sulfate solution when reacting with sulfuric acid.
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.
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
Yes, the darkening of a copper penny is a chemical change. When copper is exposed to air and moisture, it reacts with oxygen and carbon dioxide, leading to the formation of copper oxide and other compounds that give the penny a darker appearance. This process alters the chemical composition of the copper, indicating a chemical change rather than a physical one.
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.
Copper turns green due to a chemical reaction with oxygen and other elements in the environment, forming a layer of copper oxide and copper carbonate on the surface. This process is known as oxidation and is a chemical change.
"chemical"
it is used as a catalyst in chemical reactions
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.
