Here we assume that disintegration has occur so the normal t½ formular will not be used
mathematically we..⅛×5600 =700
therefore it is about 700years option A

Explanation:
<span>The value of enthalpy of a reaction can be a useful tool in determining the type of reaction it is. If the enthalpy is negative the reaction is exothermic and if the enthalpy is positive the reaction is endothermic. Hope this answers the question. Have a nice day.</span>
the molarity of KCl solution prepared by dissolving 0.898 mole of KCl in 250 ml water is calculated using the below formula
molarity= moles/volume in liters
moles= 0.898 moles
volume in liters= 250/1000 =0.25 liters
molarity is therefore= 0.898/0.25= 3.592 M
