Question 1

Given the reaction:

2KMnO₄ + 10 KI + 8 H₂SO₄→ 6 K₂SO₄ + 2 MnSO₄ + 5 I₂ + 8 H₂O

How many moles of H₂SO₄ are required to produce 2.0 moles of I₂, given the other reactants are in excess?
◦ 0.80 mol
◦ 1.3 mol
◦ 3.2 mol
◦ 4.0 mol
◦ 1.6 mol

Question 2

Given the reaction:

P₄(l) + 6 Cl₂(g) → 4 PCl₃(l)

If the percent yield is 82%, what mass of P₄ is required to obtain 2.30 g PCl₃ (Cl₂ in excess)?
◦ 0.63 g
◦ 0.52 g
◦ 0.43 g
◦ 0.16 g
◦ 0.95 g
