Part 1)
Cobalt-60 was used in radiation therapy. It creates ionizing radiation which damages DNA of cancer cells. Given that its half life is 1925.20 days, how long does it take for 25% of a sample to decay? Answer in number of days
Part 2)
Hydrazine is somewhat toxic. Use the half reactions shown below to explain why household bleach(a highly alkaline solution of sodium hypochlorite) should not be mixed with household ammonia or glass cleansers that contain ammonia.
ClO- + H20 + 2e- --> 2OH- + Cl- E^o = 0.90V
N2H4 + 2H20 + 2e- --> 2NH3 + 2OH- E^o = -0.10V
