Answer & Explanation:5.
For many years alchemists tried to convert lead to gold. All of the
following reasons for their failure are true EXCEPT
A. To change lead into gold,
alchemists needed to remove three protons from the nucleus of lead.
B. Alchemists were not able to
“cook” the reaction hot enough to provide the energy required to
remove protons from the lead nucleus. The energy required to overcome the
lead atom’s binding energy is enormous compared to the amount supplied by
alchemist’s “cooking”.
A.
C. Alchemists
did not know then that it is impossible to add or remove particles from the
nucleus of an atom.
D. Alchemists were conducting
ordinary chemical reactions, which only involve valence electrons and not the
nucleus. In chemical reactions atoms can change partners but not change their
elemental identity
E. Reacting lead carbonate with
acid, alchemists only broke old bonds and formed new ones. Breaking bonds
requires only a fraction of the energy required to overcome the binding
energy in the nucleus.
