When a substance loses its luster, it typically means that a protective outer layer has been removed or altered, rather than a chemical change occurring. This can result from physical processes like scratches or oxidation that disrupt the surface, causing light to be reflected differently and the substance to appear dull.

A atom loses an electron to another atom is an example of physical or chemical change?
This is an example of a chemical change. When an atom loses an electron to another atom, it undergoes a chemical reaction, resulting in the formation of new chemical compounds with different properties.
Is oxidation a physical change?
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
A substance loses energy during what two processes?
A substance loses energy during cooling and evaporation processes. During cooling, heat is transferred away from the substance, lowering its temperature. During evaporation, the substance loses energy as molecules escape from its surface, causing it to undergo a phase change from liquid to gas.
What does oxiation mean?
There is no term "oxiation." It may be a misspelling or misunderstanding. If you meant "oxidation," it refers to a chemical reaction in which a substance loses electrons, usually to oxygen, resulting in the substance being oxidized. Oxidation can lead to changes in the physical and chemical properties of the substance.
Is steam condenses on a cold window chemical change?
No, condensation of steam on a cold window is a physical change, not a chemical change. The water vapor in the steam undergoes a change in state from gas to liquid as it loses heat energy to the cold window, but the water molecules themselves remain unchanged.
A atom loses an electron to another atom is an example of physical or chemical change?
This is an example of a chemical change. When an atom loses an electron to another atom, it undergoes a chemical reaction, resulting in the formation of new chemical compounds with different properties.
When an atom gains or loses a valance electron does it have a physical or chemical change?
That is a chemical change.
Does oxidation mean it turns something to gas?
No, oxidation does not always turn something into a gas. Oxidation is a chemical reaction in which a substance loses electrons, leading to a change in its chemical composition. This process can result in various outcomes, such as the formation of a gas, solid, or solution.
Is oxidation a physical change?
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
Is removing water from a substance a chemical reaction?
In most cases, removing water is a physical change rather than a chemical change. This is often no more than a drying process where water evaporates from a substance. However there are some chemical reactions that remove water from a substance. Of course, the substance itself will also change in this case. An example is copper sulphate. Its normal composition includes water (CuSO4 pentahydrate) but as it is heated, it loses water molecules and becomes CuSO4 trihydrate.
A substance loses energy during what two processes?
A substance loses energy during cooling and evaporation processes. During cooling, heat is transferred away from the substance, lowering its temperature. During evaporation, the substance loses energy as molecules escape from its surface, causing it to undergo a phase change from liquid to gas.
Is steam turning into water chemical or physical?
Steam turning into water is a physical change called condensation. The change occurs when the water vapor loses heat energy and transforms into liquid water. No new substances are formed during this process.
Give two definitions of oxidation?
Oxidation is a chemical reaction in which a substance loses electrons, resulting in an increase in oxidation state. Oxidation can also refer to the process of combining a substance with oxygen, leading to a chemical change.
Is bouncing a ball a chemical change?
yes No. Nothing changes in its chemical nature.
When a metal loses its luster - is it because of oxidation?
Yes, when a metal loses its luster, it is often due to oxidation. Oxidation is a chemical reaction between the metal and oxygen in the air that forms a dull layer on the metal's surface, called an oxide layer, which can diminish its shiny appearance. Regular cleaning and maintenance can help prevent or reduce oxidation on metals.
What does oxiation mean?
There is no term "oxiation." It may be a misspelling or misunderstanding. If you meant "oxidation," it refers to a chemical reaction in which a substance loses electrons, usually to oxygen, resulting in the substance being oxidized. Oxidation can lead to changes in the physical and chemical properties of the substance.
What is the chemical formula of oxidation?
The general chemical formula for oxidation is A + B -> AB. This represents a chemical reaction where substance A loses electrons and substance B gains electrons.
