![1. Recently, the toxicity of cadmium became a concern, but nickel-cadmium (nicad)
batteries are still used commonly in many devices. The overall cell reaction is
Cd(s) + 2 NiO(OH)(s) + 2 H20(1) →2 Ni(OH)(s) + Cd(OH)2(s)
A certain nicad battery weighs 13.3 g and has a capacity of 400. mA hr (that is, the cell
can store charge equivalent to a current of 400. mA flowing for 24 minutes).
a. wnat is uie capacity of this cell in coulombs?
