The Russian Space Agency uses potassium superoxide (KO2) for chemical oxygen generators in their spacesuits. If the mass of O2 is 380 grams, what mass of KO2 is needed in the reaction? 4KO2 + 2H2O + 4CO2 --> 4KHCO3 + 3O2

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.
