Question 1

The chemical reaction occurring during the discharge of a lead storage battery can be represented by the equation:

What mass of lead sulfate would result from the complete reaction of 41.4 g of lead?
◦ 57.6 g
◦ 60.5 g
◦ 105 g
◦ 115 g
◦ 121 g

Question 2

The chemical reaction occurring during the discharge of a lead storage battery can be represented by the equation:

Pb(s) + PbO₂(s) +2 H₂SO₄(aq) → 2 PbSO₄(s) + 2 H₂O(l)

Which is the limiting reagent and the amount of PbSO₄ produced if 53.0 g of Pb, 77.3 g of PbO_2, and 534 mL of 0.544 M solution of H₂SO₄ is used?
◦ limiting reagent PbO₂, 196 g PbSO₄
◦ limiting reagent Pb, 77.6 g PbSO₄
◦ limiting reagent Pb, 155 g PbSO₄
◦ limiting reagent H₂SO₄, 88.1 g PbSO₄
◦ limiting reagent H₂SO₄, 176 g PbSO₄
