Hydrogen sulfide reacts with sulfur dioxide to give H2O and S, H2S + SO2 = H2O + S(solid), unbalanced. If 6.0 L of H2S gas at 750 torr produced 3.2 g of sulfur, what is the temperature in Celsius?
The temperature is 810 °C.
There are four steps in this problem:
- Write the balanced chemical equation.
- Calculate the moles of sulfur.
- Calculate the moles of H₂S.
- Use the Ideal Gas Law to calculate the temperature.
1. Write the balanced chemical equation
2H₂S + SO₂ → 2H₂O + 3S
2. Calculate the moles of sulfur
Moles of S = 3.2 g S ×
3. Calculate the moles of H₂S
Moles of H₂S = 0.0998 mol S ×
4. Calculate the temperature
