Answer:
2 moles of SO₂
Step-by-step explanation:
Equation of reaction
H₂S + 3H₂SO₄ → 4H₂O + 4SO₂
From the equation of reaction above,
1 mole of H₂S will produce 4 moles of SO₂
1 mole of H₂S = 4 moles of SO₂
0.5moles of H₂S = zmoles of SO₂
z = (0.5*4) / 1
z = 2 moles of SO₂
0.5 moles of H₂S will produce 2 moles of SO₂
