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.
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
No. It is a physical process, so it technically isn't a reaction.
In a chemical reaction, the thermodynamic product is the most stable product, while the kinetic product is the product that forms the fastest. The difference lies in the energy levels and reaction rates of the products.
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
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.
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials

A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
energy released by the reaction or energy absorbed.
A physical change is reversible, a chemical change is not.
reactant + reactant = product
a physical change is reversible but a chemical change is irreversible
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
