Question

4. Conservation of energy tells us that energy cannot be created or destroyed. Clearly, energy is required for radioactivity to occur. Where is this energy coming from? (10 points) 5. How could the age of this fragment be determined? (10 points) 6. Asteroids can be classified into two broad groups based on their composition and location: carbon-rich asteroids dominate the outer part of the asteroid belt, whereas metal-rich asteroids dominate the inner part of the belt. Analysis of the fragment we have discussed in this project reveals that it contains nearly equal amounts of metals and carbon. Can we conclude that the original asteroid had a similar composition? Form a hypothesis about the origin of this asteroid based on the available information. (20 points)

Explanation / Answer

4.Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles.
5.use the first law of chemical kinetics i.e. log(C/C0) =-kt
