Question

Give examples of some chemical reversible changes.

Answer 1

N2+O2=NO2
IT is a reversible chemical change

Answer 2

Example of chemical reversible change are:-

When iron rusts, it reacts with oxygen in water or in air to create a new compound called iron oxide (rust). As in every chemical reaction, no mass is lost or gained. The same atoms from the original material are in the new materials, but in different places. If you weighed the iron oxide in this rusting ship, it would weigh the same as the original iron and oxygen.
