Transcribed Image Text:### Chemistry Problem: Gas Production in a Chemical Reaction
#### Problem Statement:
The following reaction occurs:
793 mL of a 0.823 M sodium sulfide solution is reacted with 0.452 L of a 0.923 M solution of phosphoric acid. One of the products is the insoluble gas, H₂S.
Determine the volume of hydrogen sulfide gas produced at 45.12°C and 834.2 mm Hg.

In this problem, you are provided with the reactants:
1. 793 mL of a 0.823 M sodium sulfide solution
2. 0.452 L of a 0.923 M phosphoric acid solution
You are asked to find the volume of the created hydrogen sulfide (H₂S) gas at specific conditions of temperature and pressure, specifically at 45.12°C and 834.2 mm Hg. This will involve the use of the ideal gas law and stoichiometric conversions between reactants and products.
To solve this problem, follow these steps:
1. Determine the moles of each reactant.
2. Identify the limiting reactant.
3. Use stoichiometry to find the moles of H₂S gas produced.
4. Convert the moles of H₂S to volume using the ideal gas law (PV=nRT).
#### Note:
Under real-world conditions, gas laws and stoichiometric relationships must consider potential deviations from ideal behavior, but for educational purposes, we assume ideal gas conditions.
