Question: The NiCad cell, which generates a voltage of 1.40 V, uses the reaction Ni(OH) 4 (s) + Cd(s) Ni(OH) 2 (s) + Cd(OH) 2

The NiCad cell, which generates a voltage of 1.40 V, uses the reaction

Ni(OH)₄ (s) + Cd(s) → Ni(OH)₂ (s) + Cd(OH)₂ (s)

A particular cell contains 4.50 g of Cd and an excess of Ni(OH)₄ Assuming that the cell provides a constant current of 0.100 amperes, the maximum time (hours) for which it could provide the current is...
