Nuclear fission describes a nuclear reaction in which a heavy nucleus, such as uranium, is bombarded by neutrons causing the atom to split into two or more smaller atoms. The fission reactions take relatively little energy input to occur and do not occur in nature. Fission produces many highly radioactive particles and releases large amounts of energy. Predict the changes in the nucleus as uranium-235 is split in a nuclear reactor.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
