Explain why , hydrogen and oxygen are considered elements whereas water is not considered an element .

Calculate the energy released in joules and MeV in the following nuclear reaction : ._(1)^(2) H+_(1)^(2) rarr _(2)^(3)He + _(0)^(1)n Assume that the masses of ._(1)^(2)H, _(2)^(3)He and neutron (n) respectively are 2.020, 3.0160 and 1.0087 in amu.

An isotopic species of lithium hydride LiH is a potential fuel in a reactor on the basis of reaction ._(3)^(6)Li+._(1)^(2)H rarr 2._(2)^(4)He . Find the possible power production in kW assciated with the consumption of 1g of .^(6)Li^(2)H per day, if the efficiency of the process is 100 % . [M(._(3)^(6)Li) = 6.01702 am u, M(._(1)^(2)H) = 2.01474 am u, M(._(2)^(4)He) = 4.00388 am u]

The explosive in a Hydrogen bomb is a mixture of _(1)H^(2),_(1)H^(3) and _(3)Li^(6) in some condensed form.The chain reaction is given by [_(3)Li^(6)+_(0)n^(1)rarr_(2)He^(4)+_(1)H^(3)] [_(1)H^(2)+_(1)H^(3)rarr_(2)He^(4)+_(0)n^(1)] ,During the explosion the energy released is approximately (Given: ,M(Li)=6.01690"amu",M(_(1)H^(2))=2.01471"amu",M(_(2)He^(4))=4.00388 ,"amu",and "1amu=931.5MeV]

Calculate the energy released in MeV during the reaction ._(3)^(7)Li + ._(1)^(1)H to 2[._(2)^(4)He] if the masses of ._(3)^(7)Li, ._(1)^(1)H and ._(2)H_(4)He are 7.018, 1.008 and 4.004 amu respectively.
