- A sample of rock was found to contain 8.23 mg of rubidium-87 and 0.47 mg of strontium-87.. (a) Calculate the age of the rock if the half-life of the decay of rubidium by emission is 4.71010 y. (b) If some S3887r was initially present in the rock, would the rock be younger, older, or the same age as the age calculated in (a)? Explain your answer.arrow_forwardWrite a balanced equation for each of the following nuclear reactions: (a) the production of 17O from 14N by a particle bombardment. (b) the production of 14C from 14N by neutron bombardment. (c) the production of 233Th from 232Th by neutron bombardment. (d) the production of 239U from 238U by H12 bombardmentarrow_forward
