Determine the energy released per kilogram of fuel used.

given mev per reaction, calculate energy in joules per kilogram of reactants.
consider 1 mole of uranium-235 to be a mole of “reactions” (molar mass = 235 grams).

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
