After James Chadwick discovered the neutron, atomic theory expanded to include isotopes. Isotopes have many practical uses. For
example,
scientists use the relative amount of carbon-12 to carbon-14 in ancient bones to determine how old they are.

A 2
B 6
C 8
D 14

Explanation:
Hello!
In this case, since the average rate of reaction is computed as a change given by:
In such a way, given the concentrations at the specified times, we plug them in to obtain:
Whose negative sign means the concentration decreased due to the decomposition.
Best regards!
