A Comprehensive Analysis of the Given Chemical Equation

Understanding the Chemical Equation

The given chemical equation is $${ 8 \text{Ag}_2\text{S} \rightarrow 10 \text{Ag} + \text{S}_8 }$$. This equation represents a chemical reaction where silver sulfide (Ag2S) is converted into silver (Ag) and sulfur (S8). In this reaction, 8 moles of silver sulfide are converted into 10 moles of silver and 1 mole of sulfur octasulfide (S8).

Balancing Chemical Equations

A balanced chemical equation is one where the number of atoms of each element is the same on both the reactant and product sides. This is crucial in understanding the stoichiometry of the reaction, which is the quantitative relationship between reactants and products. In the given equation, we need to determine if it is balanced or not.

Analyzing the Given Equation

Let's analyze the given equation to determine if it is balanced or not. On the reactant side, we have 8 moles of Ag2S, which means we have a total of 16 moles of silver (Ag) and 8 moles of sulfur (S). On the product side, we have 10 moles of silver (Ag) and 8 moles of sulfur (S8).

Determining the Balance of the Equation

To determine if the equation is balanced, we need to compare the number of atoms of each element on both sides of the equation. On the reactant side, we have 16 moles of silver (Ag) and 8 moles of sulfur (S). On the product side, we have 10 moles of silver (Ag) and 8 moles of sulfur (S8).

Conclusion

Based on the analysis, we can conclude that the given chemical equation is not balanced. The number of silver (Ag) atoms on the product side (10 moles) is not equal to the number of silver (Ag) atoms on the reactant side (16 moles). Therefore, the correct answer is:

A. It is not balanced because the products contain a different number of sulfur (S) atoms than the reactants.

Why is Balancing Chemical Equations Important?

Balancing chemical equations is crucial in understanding the stoichiometry of a reaction, which is the quantitative relationship between reactants and products. It helps us to determine the amount of reactants and products required for a reaction to occur. In addition, balancing chemical equations is essential in predicting the products of a reaction and understanding the energy changes that occur during a reaction.

How to Balance Chemical Equations

Balancing chemical equations involves adjusting the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation. This can be done by adding or subtracting coefficients from the reactants and products. The coefficients are numbers that are placed in front of the formulas of the reactants and products to indicate the number of moles of each substance that is involved in the reaction.
