    ionistaion energy of H atom and energy released

    for part a , the question want ionistaion energy ... why shouldnt it be H2 atom dissciate to become 2H+ ion? but the solution gives H+ + e- = H instead? for part c , shouldnt the loss of mass from 10.0kg of LiD= 0.002988x(10^6)x10= 29.88kg? then use E= mc^2 to proceed?
