A chemical change is a process that results in the formation of new substances with different chemical compositions from the original substances. This process involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include burning, rusting, and digestion.

Is sublimation of iodine represents a chemical change?
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Why are volcanoes a chemical change?
Volcanoes involve the release of gases, such as sulfur dioxide and carbon dioxide, through chemical reactions. These gases are produced as a result of the breakdown of rocks and minerals inside the Earth's crust, which represents a chemical change. Additionally, the formation of new minerals within volcanic rocks during the cooling process also represents a chemical change.
Is corrosiveness a physical change or a chemical change?
Corrosion represents a CHEMICAL change.
When table salt is added to water the ionic compound dissolves. Does this represent a physical change or a chemical change?
Dissolving table salt in water represents a physical change, not a chemical change. The salt molecules remain intact and simply disperse in the water, without any chemical bonds being broken or formed.
Is the chemical formula H2o physical or chemical change?
The chemical formula H2O represents water. It is a chemical formula that describes the composition of a substance, in this case, water. Therefore, it is related to a chemical change rather than a physical change.
Consider the burning of gasoline and the evaporation of gasoline which process represents a chemical change and which represents a physical change?
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
Which process represents a chemical change...Melting of ice OR Evaporation of water?
The process that represents a chemical change is the evaporation of water. This is because the bonds between the H and O atoms in water molecules are broken during evaporation, leading to a change in the substance's chemical composition. The melting of ice, on the other hand, is a physical change where the state of water changes from solid to liquid without altering its chemical structure.
Is sublimation of iodine represents a chemical change?
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Is breaded toast a physical or chemical change?
Toasting bread represents a chemical change.
Is digestion of a candy bar a physical change or chemical change?
Chemical property

Is a spoiled pear a physical or chemical change?
Spoiled food of any kind represents a CHEMICAL change.
When an old car sits in a junk yard and rusts is it a chemical change?
Rusting of a metal, be it a car or any other item, represents an oxidation reaction, and this is a chemical change because the metal is becoming a metal oxide in the process.
What step in the digestive process represents a chemical change in food?
From the moment ingested food is exposed to saliva to acids in the stomach until it is absorbed into the blood in the stomach or intestines different food products are undergoing chemical change.
Is the color change experienced by the statue of liberty a physical or a chemical change?
i m pretty sure a colour change represents a Chemical change
Is a banana ripening on a counter a chemical change?
Ripening is a chemical process.
Is a pancake a physical change or chemical change?
Cooking is a chemical process.
