Chemical equations are a fundamental aspect of chemistry, representing the transformation of one or more substances into another. However, not all chemical equations are balanced, meaning the number of atoms of each element is the same on both the reactant and product sides. In this article, we will explore the concept of balancing chemical equations and determine which of the given equations is balanced.

What is a Balanced Chemical Equation?

A balanced chemical equation is a chemical equation in which the number of atoms of each element is the same on both the reactant and product sides. This means that the number of atoms of each element is conserved during the reaction. A balanced chemical equation is essential in chemistry as it helps to:

  • Predict the products of a reaction: By balancing a chemical equation, we can predict the products of a reaction and understand the stoichiometry of the reaction.
  • Calculate the amount of reactants and products: A balanced chemical equation allows us to calculate the amount of reactants and products required for a reaction.
  • Understand the mechanism of a reaction: A balanced chemical equation provides insight into the mechanism of a reaction, helping us to understand how the reactants are converted into products.

How to Balance a Chemical Equation

Balancing a chemical equation involves adding coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides. The steps involved in balancing a chemical equation are:

  1. Write the unbalanced equation: Write the chemical equation with the reactants on the left and the products on the right.
  2. Count the atoms: Count the number of atoms of each element on both the reactant and product sides.
  3. Add coefficients: Add coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides.
