Irreversible chemical change.
physical because water is H2O and ice is H2O also
A gas released during a chemical reaction is a chemical change.
Answerchemical reaction
Digesting a banana is a chemical reaction, an ireversible change.
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Physical
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
that is because salt is a physical matter
A physical change doesn't involve chemical reactions, change of the molecule structure.The chemical reactivity is about the ability of an element or compound to realize chemical reactions.
physical because water is H2O and ice is H2O also
physical change ex:Ripping, cutting, folding. physically changing the appearance of something. Burning can be either a physical or chemical change.
Chemical reaction
A gas released during a chemical reaction is a chemical change.
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
A catalyst undergoes no chemical change during a chemical reaction.
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
