Question

Can a chemical reaction be reversed by using physical means? why?

Answer 1

Answer:

PHYSICAl CHANGES:are changes that occur in the physical properties of the substance,like shape,size and nature . Physical changes may or may not be reversible changes .Like turning of water into ice is an example of reversible changes but growth in height is irreversible change.

CHEMICAL CHANGES:are changes that occur in the chemical properties of substance like its flammability , radio activity etc.All chemical changes are irreversible changes once the chemical properties of substance are changed,it becomes another substance.Thus it cannot return to its original state
