Question

why do we need to balance a chemical equation? explain it with an example

Answer 1

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side

Answer 2

hemical equations need to be balanced in order to satisfy the law of conservation of matter, which states that in a closed system matter is neither created nor destroyed.


Take for example the combustion of methane
