Introduction:
In the physical change corresponds to change the form of chemical substance, the composition of the substance does not change. By the physical change, the physical properties of the substance change for example color, size, density, shape.
In the chemical reaction, reactants are combined to a formed product, that may or may not have the same property of the reactants.
b.
To determine:
If the stated change corresponds to a physical change or a chemical reaction in the given process.
Introduction:
In the physical change corresponds to change the form of chemical substance, the composition of the substance does not change. By the physical change, the physical properties of the substance change for example color, size, density, shape.
In the chemical reaction, reactants are combined to a formed product, that may or may not have the same property of the reactants. Chemical bonds formed during the chemical reaction. The chemical reaction can be reversible and irreversible.
