Answer:
7664.06249 N/m
Explanation:
m = Mass of mug = 0.5 kg
x = Compression of spring = 0.08 m
h = Height of fall = 5 m
g = Acceleration due to gravity = 9.81 m/s²
The kinetic energy of the spring and potential energy of the fall are conserved

The spring constant of the spring is 7664.06249 N/m
The chemical change is are to water breaking down into hydrogen and oxygen.
