Answer:
E = 4.78×10^−19 J
Explanation:
The chemical equation for the energy of a photon is given by:
E =hν , where h is the Planck constant and ν is the frequency.
E =hν = 6.626×10^−34 Js × 7.21×10^ 14
s−1 = 4.78 × 10^−19 J
I looked up the half life for nickel-63 and then used the half life formula which is No=Nt*e^(kt) so the final answer is 20000 years for 26g of nickel-63 to decay to 6.5g
