3. A radioactive substance Zevonium decays into 4 different daughter products, Wachtelite Kunkelate. Calderonium, and Kortchmarium. Wachtelite is radioactive and has a boiling point of 1200 °C. Kunkelate is stable and has a boiling point of -112 . Calderonium is stable and has a boiling point of 1300 °C, and Kortchmarium is radioactive and has a boiling point of -150°C. Which of these daughter products would be most useful in aging recks.

A certain radioactive substance decays at a rate proportional to its remaining mass M. a. Express this rate of decay as a differential equation. b. When a living organism dies it ceases to replace the carbon isotope C-14, and 48. the C-14 that is present decays with a half-ife of about 5730 years. If archeologists discover a fossilized bone that has 30% of the C-14 of a live bone, approximately how old is it?
