Question

what is a balanced chemical equation? why should chemical equations be balanced.​

Answer 1

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. 

Answer 2

Step-by-step explanation:

$<font color = red>$

What is a balanced chemical equation?

$<font color = blue>$

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

$<font color = red>$

Why should chemical equations be balanced?

$<font color = blue>$

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. Balancing chemical equations is a process of trial and error.
