Introduction

Balancing chemical equations is a crucial step in understanding chemical reactions. It involves making sure that the number of atoms for each element is the same on both the reactant and product sides of the equation. In this article, we will focus on balancing the given incomplete reaction: Ba(ClO3)2 → + 3 O2. We will identify the type of reaction, balance the equation, and determine the other product.

Identifying the Type of Reaction

The given reaction involves the decomposition of barium chlorate (Ba(ClO3)2) to produce oxygen gas (O2). This type of reaction is known as a decomposition reaction, where a single compound breaks down into two or more simpler substances.

Balancing the Equation

To balance the equation, we need to make sure that the number of atoms for each element is the same on both sides. Let's start by counting the number of atoms for each element on the reactant side:

Ba: 1
Cl: 2
O: 6

On the product side, we have:

O: 6

We can see that the number of oxygen atoms is already balanced. However, we need to balance the number of barium and chlorine atoms. To do this, we can add a coefficient of 3 in front of the oxygen gas (O2) on the product side:

Ba(ClO3)2 → Ba + 3 O2

However, this is not a balanced equation yet. We need to add a coefficient of 2 in front of the barium atom on the product side to balance the number of barium atoms:

Ba(ClO3)2 → 2 Ba + 3 O2

Now, let's count the number of atoms for each element on both sides:

Ba: 2 (reactant) = 2 (product)
Cl: 2 (reactant) = 6 (product)
O: 6 (reactant) = 6 (product)

The equation is now balanced.

Determining the Other Product

In addition to oxygen gas (O2), the other product of the reaction is barium (Ba). The balanced equation is:

Ba(ClO3)2 → 2 Ba + 3 O2

Conclusion

Balancing chemical equations is an essential step in understanding chemical reactions. By identifying the type of reaction, balancing the equation, and determining the other product, we can gain a deeper understanding of the reaction. In this article, we balanced the given incomplete reaction and determined the other product to be barium (Ba).
