Physical reactions mean that the substance hasn't been altered in terms of its composition. For example, liquid water turning into an ice cube is a physical change. It is still H2O - just different form. However, burning paper is chemical change, since ash + H2O + CO2 is not paper.

What are the different between chemicals and physical reactions?
chemical effects it more than pie does
Can a chemical and physical change also be called a chemical and physical reaction?
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.
What is the total of chemical and physical reactions?
Chemical reactions involve a change in chemical composition, while physical reactions involve a change in state or appearance without changing the chemical composition. Together, they encompass the various transformations that can occur in matter.
How does a physical reaction different form a chemical reaction?
A physical reaction involves changes in the state or appearance of a substance without altering its chemical composition, such as melting, freezing, or dissolving. In contrast, a chemical reaction results in the formation of new substances with different chemical properties through the breaking and forming of bonds, as seen in processes like combustion or rusting. Essentially, physical reactions are reversible while chemical reactions often produce irreversible changes.
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.
How something reacts?
How something reacts depends on a lot of different things. Physical reactions are much different than chemical reactions for example.
Which is a characteristic of chemical equilibrium but not physical equilibrium?
Reversibility of reactions is a characteristic of chemical equilibrium but not physical equilibrium. In chemical equilibrium, the forward and reverse reactions continue to occur, while in physical equilibrium, there is no net change in the physical state of a substance.

Is reactions a chemical or physical?
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.
Can chemical and physical changes be called chemical and physical reactions?
yes it can be called physical and chemical reaction
What are the factors classified as chemical and physical reaction?
Chemical reactions involve the formation of new substances with different chemical properties, such as rusting of iron. Physical reactions involve changes in the physical state or appearance of a substance without changing its chemical composition, like melting ice.
What are examples of chemical reaction?
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.
What reaction is in antacids chemical or physical?
Chemical reactions are of course chemical changes.
How dos the same type of rock produce different soils in two different climates?
Chemical and physical reactions breaking down the rock are different.
Can a chemical and physical change also be called a chemical and physical reaction?

Is pasteurization chemical or physical change?
Pasteurization involve chemical reactions.
