Suppose a nucleus “swallows” a neutron and then decays not by fission but by beta-minus decay, in which it emits an electron and a neutrino. Which nuclide remains after this decay ?
If we split a nucleus into two smaller nuclei, with a release of energy, has the average binding energy per nucleon increased or decreased?
The uranium ore mined today contains only 0.72% of fissionable , too little to make reactor fuel for thermal-neutron fission. For this reason, the mined ore must be enriched with . Both role="math" localid="1661753958684" and are radioactive. How far back in time would natural uranium ore have been a practical reactor fuel, with a ratio of 3.0%?
Show that the energy released when three alpha particles fuse to formis. The atomic mass ofrole="math" localid="1661752248572" is, and that ofis 12.0000u.
Coal burns according to the reaction . The heat of combustion is of atomic carbon consumed. (a) Express this in terms of energy per carbon atom. (b) Express it in terms of energy per kilogram of the initial reactants, carbon and oxygen. (c) Suppose that the Sun () were made of carbon and oxygen in combustible proportions and that it continued to radiate energy at its present rate of . How long would the Sun last?
