What is the purpose of balancing a chemical equation?

Answer 1

To determine the stoichiometric relationship between species.

To be sure, there are many reasons to balance chemical reactions or equations, but figuring out the stoichiometric relationship between species is, in my opinion, the primary one.

Say, for instance,

#3A+2B -> 4C+1D#

Assume that A, B, C, and D are distinct chemical species, and that the reaction described above is balanced.

It is possible to infer from the reaction that 3 moles of A are needed to produce 4 moles of C, and 2 moles of B are needed to produce 4 moles of C.

The purpose of balancing a chemical equation is to ensure that the law of conservation of mass is obeyed. This means that the number of atoms of each element on the reactant side must equal the number of atoms of the same element on the product side, thereby maintaining mass balance in the reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
