why should chemical equation be balanced
Answers
A chemical equation should be balanced in order to comply with the law of conservation of mass which states that matter can neither be created nor destroyed during a chemical equation. If an equation is not balanced it shows that either matter is Destroyed or Created during the reaction which should not happen.
Because that’s how chemistry works. You have to understand, the idea that matter (or in this case, atoms) can not be created or destroyed by chemical means was a MAJOR leap forward in science. Until then, it was thought that you could magically make or destroy matter, or even convert one element into another, by simply using the right chemical processes. Once Dalton and Lavoisier figured out how atoms really react, we finally began the modern age of chemistry. Rule 1: You MUST have the same number of atoms at the beginning and the end of the reaction.
