Which layer of the atmosphere is chemically stratified, with the lightest molecules riding above heavier molecules?

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.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %

I’m an electrically neutral atomic any element, there are equal numbers of
