Arrange the gases in increasing order of the number of atoms that make up its molecule from left to right. CH4 CO2 C2H2 Br2. For a given element, in which state of potential energy would you expect to have (a) the greatest and (b) the least amount of potential energy? Explain you answers in terms of the chemical energy holding atoms together.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
