A chemical change involves a transformation that alters the chemical composition of a substance, such as rusting, burning, or digestion. In contrast, a physical change affects only the form or appearance without changing the substance's chemical identity, like melting ice or dissolving sugar in water. Therefore, any process that retains the original substance's chemical properties would not be classified as a chemical change.
What else can I help you with?
All of the following are examples of chemical change except?
All of the following are examples of chemical change except physical changes such as melting, freezing, or dissolving. In a chemical change, the substances involved undergo a transformation that results in new chemical properties, while in a physical change, the substance remains the same at the molecular level. Examples of chemical changes include rusting, burning, and digestion.
Is puddles drying a physical change?
Does the water ever change into anything except water? No, so it's not a chemical change.
What is the following causes of chemical weathering of rock and soil except?
The causes of chemical weathering include exposure to water, oxygen, carbon dioxide, and acids. Erosion is a physical weathering process, not a chemical one.
Why the rusting of an iron pole is not physical change?
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
All are examples of chemical reactions except?
Breaking a glass. This is a physical change as the glass does not transform into a different substance. Chemical reactions involve the breaking and forming of chemical bonds to produce new substances.
Is puddles drying a physical change?
Does the water ever change into anything except water? No, so it's not a chemical change.
What if your body converts chemical energy to all of the following EXCEPT?
Nuclear energy is the only energy that the human body does not produce.
In game Donald bartheleme is satirizing all of the following except?
Characters in the book are willing to accept change.
What is the following causes of chemical weathering of rock and soil except?
The causes of chemical weathering include exposure to water, oxygen, carbon dioxide, and acids. Erosion is a physical weathering process, not a chemical one.
What is the weathering in which the chemical composition has changed?
It's called chemical weathering/chemical change. Similar to the physical change of matter, except the chemical composition changes causing it to become something completely different. For example: iron turns to rust, silver tarnishes and copper turns green.

What substance can be decomposed by a chemical change Ne N2O HF or H2O?
The substance that can be decomposed by a chemical change is N2O (nitrous oxide) because it undergoes a decomposition reaction when exposed to heat or a catalyst, breaking down into its constituent elements nitrogen and oxygen.
What is chysical change?
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Is grinding salt a chemical or physical change?
physical
What quantity describes how quickly you change your speed?
acctually, you are describing two very similar quantities. th quantity that describes how quickly you change your speed, or how fast you are going is your acceleration, measured in distance per unit of time squared. the quantity that describes how quickly you change your direction is called velocity and it is identical to speed except in the fact that velocityshows how fast you go in a certain direction, or how quickly you change your direction
