Lead storage batteries are rated by ampere hours, that is, the number of amperes they can deliver in an hour. (a) Show that 1 A ? h 5 3600 C. (b) The lead anodes of a certain lead-storage battery have a total mass of 406 g. Calculate the maximum theoretical capacity of the battery in ampere hours. Explain why in practice we can never extract this much energy from the battery. (Hint: Assume all of the lead will be used up in the electrochemical reaction and refer to the electrode reactions on p. 833.) (c) Calculate E cell and DG for the battery.

Personalized ■ Socialized changing people for the greater good ■ Personalized changing people for your own good Uncertainty ● Examples include lack of knowledge, lack of resources, etc ● More concrete, taskorientated forces when there is more uncertainty ● Related to transformational and influences whether transformations are needed or not Does
