Would you say reversible chemical reactions are examples of a physical change or chemical change?explain your answer
Answers
Answer:
A Physical change alters the form of a substance, but does not change it to another substance. These changes occur when matter (Anything that takes up space and has mass) changes its physical property but not its chemical nature. Eg. Folding of paper.
A chemical change is a change which matter undergoes when it becomes a new or different matter. When a substance undergoes a chemical change, in is changes into a different substance with different properties. To identify chemical change, look for signs like colour change, bubbling, fizzling, light production, smoke and presence of heat. Eg. Baking of cake.
The only reversible chemical change is the electrolysis of water in which electricity is passed to produce hydrogen and oxygen.
Hydrogen and oxygen recombine to produce water under influence of electricity that shows it is a reversible change.
It is not a physical change as new substances are formed (hydrogen and oxygen) which have different properties than the original substance.
