During fission, the energy released comes from converting mass into energy (calculated by Einstein's famous equation: E = mc2). Therefore, if a fission reaction releases energy, and it does, that energy came from converting mass into energy, thus reducing the mass of the reactants.
The reactant's/reactants' energy is rarely every seen in the products.
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
Mainly china but very rarely america.
The anagram is the rarely-used verb form "savvied" (to savvy).
rarely used for any products. Used only on race cars windshield's.
Volcanoes are formed. Sorry, that's all I know
Molds formed on the surface of mud or clay, then, rarely are fossilized, because they are likely to erode more quickly than the mud or clay in which they were formed can harden.
Rarely, because Romania become after 1990 an underdeveloped country.
Actinium is rarely used:- as actinium-beryllium neutron source- in radiotherapy
Biodegradable products are easy to dispose of and rarely ever cause harm to the environment. By manufacturing such products, we ensure that the environment does not become polluted.
Fission reaction gets its energy from breaking up large nuclei (e.g. uranium, plutonium) into smaller ones.Fusion reaction gets its energy from combining small nuclei (hydrogen isotopes) together to make bigger ones (helium).Modern nuclear weapons are rarely pure fission or fusion, but are typically some mixture of them in a unique arrangement to get desired effects, in a desired package size, at an affordable production cost.
The most common bacterial reproduction is by Binary Fission, which is the use of mitosis to create two identical cells from one. Rarely, bacteria can reproduce sexually (ie using meiosis to create genetically different daughter cells) but this is not the most widely used mechanism.
