- A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope 118 "Sn 120 Sn Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. 0 Sn mass relative (amu) abundance 117.9 54.% 0 119.9 Continue 46.% X S evee muuraw Hill LLC.

Considering that carbon-14 decays via beta-minus radiation, ALSO write the complete nuclear decay equation.Radioactive decay is always a first-order kinetic process. Uranium-238 decays to lead-206,which is stable, with an effective half-life of 4.51 billion years. Sediment from the oceancontains 0.00150 grams uranium-238 and 4.60 x 10-4 grams lead-206. Assume lead-206 isformed only by uranium-238 decay, and there was no lead-206 present when the sedimentformed; estimate the age of the sediment.
