The difference between them is that in a chemical reaction, the chemical make up of the substance put into the experiment is changed or modified. In a physical change, only the physical attributes of the substance is changed, like size, shape, color, density, etc.

∙ 11y agoChemical reaction is when two or more chemicals combine and react to change (into one single chemical, two different chemicals that are not identical as the original or into more chemicals). Physical change refers to changes that are visible or can be sensed (usually touch for temperature change or simply color/state change).

∙ 14y agoit is diffrent becaus a physical change is when the form of an object changes and a chemical change is when 2 or more substances or two or more elements create a chemical reaction.

A chemical change transform the molecule A in another molecule B.

What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
How can you tell the difference between a chemical reaction and not a chemical reaction?
