Under certain circumstances, a nucleus can decay by emitting a particle more massive than an a-particle. Consider the following decay processes: ""_(88)^(223)Ra to ""(82)^(209)Pb + ""_(6)^(14)C . ""_(88)^(223)Ra to ""_(86)^(219)Rn + ""_(2)^(4)He Calculate the Q-values for these decays and determine that both are energetically allowed.

While the discharging of a lead storage battery following reaction take place.

Assume a constant concentration of 10.M H_(@)SO_(4)(log2 = 0.3)

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.294 g mL^(-1) to 1.139 g mL^(-) . Sulphuric acid of density 1.294 g mL^(-1) is 39% by weight and that of density 1.139 g mL^(-1) is 20% by weight. The battery hold 3.5 litre of acid and discharge. Calculate the no. of ampere hour for which the battery must have been used. The charging and discharging reactions are: Pb+SO_(4)^(2-) rarr PbSO_(4)+2e (charging) PbO_(2)+4H^(+)+SO_(4)^(2-)+2e rarr PbSO_(4)+2H_(2)O (discharging)
