No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
This is a chemical change. Chemical reactions are chemical changes.
This process involve chemical reactions but also physical changes.
Yes, chemical changes can be referred to as chemical reactions, as they involve the transformation of substances into different chemical entities. Similarly, physical changes may be described as physical reactions, as they involve alterations in the state or appearance of a substance without changing its chemical composition. However, the term "reaction" is more commonly associated with chemical changes, while "change" is often used for both types.
Physical changes refer to changes in appearance, texture, or state of matter without altering the chemical composition, such as melting, freezing, or dissolving. Chemical changes involve a rearrangement of atoms and result in the formation of new substances with different chemical properties, such as rusting, burning, or fermenting.
yes it can be called physical and chemical reaction
Chemical reactions are of course chemical changes.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
All physical changes are reversible.
These are chemical reactions (changes).
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
chemical reactions are irreversible but physical changes are reversible
A lot of chemical reactions are initiated by physical changes - specifically, heating something.
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
The chemical reactions of sulfuric acid are chemical changes.
This is a chemical change. Chemical reactions are chemical changes.
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
