Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
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.
Does a physical or chemical change take place when an apple is exposed to oxygen over time with peroxide on it?
chemical
Copper turns green when exposed to the environment chemical or physical?
it is a chemical change because copper is one of the elements on the periodical table .
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
Electrolysis of water is a chemical change. Exposing sodium chloride to sunlight would cause some heating, but no chemical changes.
Is the baseball that strikes a roof a chemical change?
Not even a change at all. My chemistry teacher always told us, if you can't reverse it so that the product will be identical as before it's a chemical reaction. I.e. Melting a Chocolate bar, it can solidify but not exactly the same (shape and whatnot) as before, or exploding, not even reversible.
What chemical change takes place when steel is exposed to water?
Corrosion occur if oxygen exist also.
Is silver tarnishing is a chemical change?
Tarnishing is a chemical change. It results from the oxidization of silver exposed to oxygen in the air that produces a thin layer of silver oxide on the surface of the silver.
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 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.
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).
