Answer is: A. the rate of decay for certain isotopes.

For example, radiocarbon dating is called Carbon-14 dating.

Carbon-14 is a radioactive isotope of carbon, with a half-life of 5730 years.

Carbon bound in fossil fuels has different isotopes than carbon in atmosphere. Fossil fuels are underground and cosmic rays do not affect carbon in them same as atmosphere carbon. Carbon in fossil fuels that is underground longer than ten thousand years has only C-12 isotope and not C-14.

Determine whether the stopcock should be completely open, partially open, or completely closed for each activity involved with t
densk [106]

Answer:

Close to the calculated endpoint of a titration - <u>Partially open</u>

At the beginning of a titration - <u>Completely open</u>

Filling the buret with titrant - <u>Completely closed</u>

Conditioning the buret with the titrant - <u>Completely closed</u>

Explanation:

'Titration' is depicted as the process under which the concentration of some substances in a solution is determined by adding measured amounts of some other substance until a rection is displayed to be complete.

As per the question, the stopcock would remain completely open when the process of titration starts. After the buret is successfully placed, the titrant is carefully put through the buret in the stopcock which is entirely closed. Thereafter, when the titrant and the buret are conditioned, the stopcock must remain closed for correct results. Then, when the process is near the estimated end-point and the solution begins to turn its color, the stopcock would be slightly open before the reading of the endpoint for adding the drops of titrant for final observation.
