Interpretation: The assumption made on carbon-14 in dating artifacts and the reason for the significance of the assumption has to be given.
Concept introduction: A process for dating ancient articles made from wood or cloth is called as radiocarbon dating (or) carbon-14 dating. Radiocarbon dating is based on
When neutrons of high energy from space collide with nitrogen-14, carbon-14 is produced in the atmosphere.
The half-life of
Answer to Problem 29A
The amount of carbon-14 in the atmosphere is constant. The importance of the assumption is it tells about the balance between the amount produced and the amount it naturally decays.
Explanation of Solution
A process for dating ancient articles made from wood or cloth is called as radiocarbon dating (or) carbon-14 dating. The nuclide that is used in dating artifacts is carbon-14
Radiocarbon dating is based on
When neutrons of high energy from space collide with nitrogen-14, carbon-14 is produced in the atmosphere.
The half-life of
Carbon-14 could be used to date wood and cloth artifacts because carbon-14 along with other isotopes of carbons reacts with oxygen to form carbon dioxide.
The assumption on carbon-14 is that carbon-14 in the atmosphere has not changed over time; the biosphere has the equal overall concentration of radiocarbon as the atmosphere due to equilibrium.
The assumption on carbon-14 is important because there is balance between the amount produced and the amount that naturally decays.
The amount of carbon-14 in the atmosphere is constant. The importance of the assumption is it tells about the balance between the amount produced and the amount it naturally decays.

Why? 3) Imagine that you used isoprene as diene - in that case you don't have to worry about assigning endo vs exo. Draw the "endo" and "exo" products of the Diels-Alder reaction between isoprene and maleic anhydride, and explain why the distinction is irrelevant here. 4) This does not hold for other dienes. Draw the exo and endo products of the reaction of cyclohexadiene with maleic anhydride.
