step 1 In answering this question, we are going to be using the extension of the ideal gas law. Recall

The gas hydrogen sulfide, H2 S, has the offensive smell...

The gas hydrogen sulfide, $\mathrm{H}_{2} \mathrm{~S}$, has the offensive smell associated with rotten eggs. It reacts slowly with the oxygen in the atmosphere to form sulfur dioxide and water. What volume of sulfur dioxide gas, in liters, forms at constant pressure and temperature from $2.44 \mathrm{~L}$ hydrogen sulfide, and what volume of oxygen gas is consumed?

Key Concepts

Balanced Chemical Equations

Balanced chemical equations express the conservation of mass in a chemical reaction. They indicate the mole ratios of reactants and products through their coefficients, which is essential for calculating the relative amounts or volumes of substances involved in the reaction.

Avogadro's Law

Avogadro's Law states that, at constant temperature and pressure, equal volumes of gases contain an equal number of molecules. This implies that the volume ratios of gases participating in a reaction are directly proportional to their mole ratios, allowing for direct volume comparisons without converting to moles.

Stoichiometry in Gas Reactions

Stoichiometry in gas reactions involves using the mole ratios from the balanced chemical equation, combined with the concept of Avogadro's Law, to relate the volumes of different gaseous substances. This enables the determination of how much volume of a product forms or a reactant is consumed based on a known volume of another gas under constant conditions.
