Is turning cloudy a chemical change?
A solution turning cloudy is evidence of 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 apple slices turning brown a physical change?
Yes, apple slices turning brown is a physical change. This browning occurs due to enzymatic reactions when the fruit's cells are exposed to oxygen, leading to the oxidation of phenolic compounds. While the appearance of the apple changes, its chemical composition remains fundamentally the same. Thus, it is a physical change rather than a chemical one.
Is copper penny turning dark a chemical change?
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.
Is turning litmus paper red from blue a chemical change?
Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.
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 a copper penny turning dark a chemical change or physical change?
Chemical.
Is turning cloudy a chemical change?
A solution turning cloudy is evidence of a chemical change.
Is bannan turning rotten a chemical or physical change?
This is 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).
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 krypton gas turning into plasma a chemical change?
Yes, it is a chemical change.
Is milk turning sour a physical or chemical change?
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
What is a flower petal turning brown a physical or chemical change?
A flower petal turning brown is a chemical change. This is because the process involves a chemical reaction that alters the composition of the pigment in the petal, causing it to change color.
Is apple slices turning brown a physical change?
Yes, apple slices turning brown is a physical change. This browning occurs due to enzymatic reactions when the fruit's cells are exposed to oxygen, leading to the oxidation of phenolic compounds. While the appearance of the apple changes, its chemical composition remains fundamentally the same. Thus, it is a physical change rather than a chemical one.
Would something turning hot to cold be a chemical change?
A decrease in temperature is a physical change, not chemical.
