Chemical equations are a fundamental concept in chemistry, representing the interaction between reactants and products in a chemical reaction. A balanced chemical equation is a crucial aspect of understanding chemical reactions, as it provides the mole ratios of reactants and products. In this article, we will explore the concept of balanced chemical equations and mole ratios, using the given equation as an example.

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 understanding the stoichiometry of a reaction, which is the quantitative relationship between reactants and products.

The Given Equation

The given equation is:

2H2S+3O2→2SO2+2H2O{ 2 H_2 S + 3 O_2 \rightarrow 2 SO_2 + 2 H_2 O }

This equation represents the reaction between hydrogen sulfide (H2S) and oxygen (O2) to form sulfur dioxide (SO2) and water (H2O).

Understanding Mole Ratios

Mole ratios are the quantitative relationships between reactants and products in a chemical reaction. They are calculated by dividing the number of moles of one substance by the number of moles of another substance. In a balanced chemical equation, the mole ratios of reactants and products are equal.

Option A: Correct Mole Ratios?

Option A presents the following mole ratios:

H2S:SO2=2:2{ H_2 S: SO_2 = 2:2 } O2:H2O=3:2{ O_2: H_2 O = 3:2 }

To determine if these mole ratios are correct, we need to analyze the given equation.

Analyzing the Equation

From the given equation, we can see that 2 moles of H2S react with 3 moles of O2 to produce 2 moles of SO2 and 2 moles of H2O. This means that the mole ratio of H2S to SO2 is indeed 2:2, as presented in Option A.

However, the mole ratio of O2 to H2O is not 3:2. Instead, it is 3:2, which is the same as the mole ratio of O2 to H2O in the given equation. This means that Option A is incorrect.

Option B: Correct Mole Ratios?

Option B presents the following mole ratios:

H2S:SO2=2:3{ H_2 S: SO_2 = 2:3 } O2:H2O=3:2{ O_2: H_2 O = 3:2 }

To determine if these mole ratios are correct, we need to analyze the given equation.

Analyzing the Equation

From the given equation, we can see that 2 moles of H2S react with 3 moles of O2 to produce 2 moles of SO2 and 2 moles of H2O. This means that the mole ratio of H2S to SO2 is indeed 2:3, as presented in Option B.

However, the mole ratio of O2 to H2O is not 3:2. Instead, it is 3:2, which is the same as the mole ratio of O2 to H2O in the given equation. This means that Option B is incorrect.

Conclusion

In conclusion, the correct mole ratios for the given equation are:

H2S:SO2=2:2{ H_2 S: SO_2 = 2:2 } O2:H2O=3:2{ O_2: H_2 O = 3:2 }

However, neither Option A nor Option B presents the correct mole ratios. The correct mole ratios are not presented in either option.

Why is it Important to Understand Mole Ratios?

Understanding mole ratios is crucial in chemistry, as it allows us to predict the quantitative relationships between reactants and products in a chemical reaction. This is essential in understanding the stoichiometry of a reaction, which is the quantitative relationship between reactants and products.

Real-World Applications of Mole Ratios

Mole ratios have numerous real-world applications, including:

  • Chemical Synthesis: Mole ratios are essential in chemical synthesis, as they allow us to predict the quantitative relationships between reactants and products.
  • Chemical Analysis: Mole ratios are used in chemical analysis to determine the composition of a substance.
  • Chemical Engineering: Mole ratios are used in chemical engineering to design and optimize chemical processes.

Conclusion

In conclusion, understanding mole ratios is crucial in chemistry, as it allows us to predict the quantitative relationships between reactants and products in a chemical reaction. The correct mole ratios for the given equation are:

H2S:SO2=2:2{ H_2 S: SO_2 = 2:2 } O2:H2O=3:2{ O_2: H_2 O = 3:2 }

However, neither Option A nor Option B presents the correct mole ratios. The correct mole ratios are not presented in either option.
