The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry.
The regulation of chemicals is the legislative intent of a variety of national laws or international initiatives such as agreements, strategies or conventions.These international initiatives define the policy of further regulations to be implemented locally as well as exposure or emission limits.

Chemistry education is important because the field of chemistry is fundamental to our world. The universe is subject to the laws of chemistry, while human beings depend on the orderly progress of chemical reactions within their bodies. [2] Described as the central science, chemistry connects physical sciences with the life sciences and applied ...
