Reaction on positive electrode (cathode):
PbSO₄₍s₎ + 2H₂O₍l₎ → 2e⁻ + PbO₂₍s₎ + 4H⁺₍aq₎ + SO₄²⁻₍aq₎.
s - solid.
l - liquid.
aq - dissolve in water.
PbSO4 is converted to Pb at one electrode (anode) and to PbO₂ at the other (cathode). Lead battery can be recharged, during recharging, an external source of energy is used.

Answer: The bond length of the HI molecule is 158.0 pm
Explanation: Please see the attachment below
In order to solve, take the total and times the percentage:
200 x 0.12 = 24 < 24 represents the number of baseballs that HAD defects.
To find which ones did not have defects, subtract 200-24, which is 176.
Answer: 176
