While the discharging of a lead storage battery following reaction take place. PbO_(2) +Pb +4H^(+) +2SO_(4)^(-2) rarr 2PbSO_(4) +2H_(2)O ,E^(@) = 2.01 Calculate the energy (in kJ) obtained from a lead storage battery in which 0.014 mol of lead is consumed. Assume a constant concentration of 10.M H_(@)SO_(4)(log2 = 0.3)

How many complexes are involved in electron transport in mitochondria ?

Let a fully charged lead storage battery contains 1.5 L 5 M H_(2)SO_(4) . What will be the concentration of H_(2)SO_(4) in the battery after 2.5 ampere current is drawn from the battery for 6 hour?

Calculate number of moles in 392 g of H_(2)SO_(4) ?

How many moles of lead (II) choride will be formed from a reaction between 6.5 g of PbO and 3.2 g of HCl?

A lead storage battery is the most important type of secondary cell having a lead anode and a grid of lead packed with PbO_(2) as cathode. A 38% solution of sulphuric acid is used as electrolyte. (Density=1.294 g mL^(-1)) battery holds 3.5 L of the acid. During the discharge of the battery, the density of H_(2)SO_(4) falls to 1.139 g mL^(-1).(20%H_(2)SO_(4) by mass) Lead storage battery is considered a secondary cell. Why?
