Answer:
anion
Explanation:
anion undergoes reduction.
cation undergoes oxidation.
Atomic mass Calcium = 40.078 a.m.u
40.078 g ---------------- 6.02x10²³ atoms
165 g -------------------- ??
165 x ( 6.02x10²³) / 40.078 => 2.47x10²⁴ atoms
hope this helps!
Answer is: nuclear fission.
Nuclear fission<span> is </span>radioactive decay<span> process in which the </span>nucleus of an atom splits into smaller parts. <span> In this process produces free neutrons and gamma photons </span><span>and releases a very large amount of </span><span>energy.
</span>Nuclear fission produces energy for nuclear power and <span>nuclear weapons.</span>
