Asealed beaker of aqueous nickel sulfide was given to you by the local chemist and you put it on the window sill. after a few days, you notice that the mixture is getting thick toward the bottom. what is the nature of the initial aqueous nickel sulfide mixture, assuming that the temperature on the sill remained approximately constant?

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.
