Think of an experiment you did in a past science class. ( nd answer the questions of wht u did in the past class)
a- describe the experiment
b- what was the experimental variable?
c- what were two control variables?
d- what was the outcome of the experiment?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
