A chemical change is a process where substances transform into new substances with different properties. This occurs through chemical reactions, where bonds between atoms are broken and formed. Indicators of a chemical change include changes in color, temperature, gas production, or the formation of a precipitate. Unlike physical changes, which only alter the state or appearance of a substance, chemical changes result in the creation of new materials.
Nitrogen oxide is formed after reaction with ozone. It is also an ozone depleting substance.
Salt water is a solution, it does not have a single chemical formula.
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
not always, like the change is in the display without change in composition then it is change of state, other then will be chemical change

The chemical formula for hydrochloric acid is HCl. The percentage strength can vary depending on the concentration of the solution. Common concentrations include 10%, 20%, and 37% hydrochloric acid.
Chemical energy is a form of potential energy stored within the chemical bonds of molecules. It is released when these bonds are broken during a chemical reaction. This energy can be converted into other forms, such as heat or mechanical energy.
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.

No, change of state is a physical change.
A change of state is a molecular change.
no a change in shape is physical change
