What is a balanced chemical equation? why should chemical equations be balanced?
Answers
Answer:
A chemical equation needs to be balanced because a chemical reaction is just a rearrangement of atoms. Atoms themselves are neither created nor destroyed during the course of a chemical reaction. The chemical equation needs to be balanced to follow the law of conservation of mass
Count and compare the number of atoms of each element on the LHS and RHS of the arrow. If the number of atoms of each element the same on both the sides are equal then equation is said to be balanced chemical equation
Law of conservation of mass governs the balancing of a chemical equation. According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced law of conservation is not applicable.
