Answer:

<h2>D. The half-life of C-14 is 5,730 years.</h2>

Explanation:

Radiocarbon dating is method used to determine the age of an animal or object which contains organic material. This can be done thanks to the properties of radiocarbon. Basically, it's a method to measure residual radioactivity, that means after the animal dies it stops exchanging carbon.

Now, one of the most common isotope is Carbon-14. Actually it's used so often that the radiocarbon dating is also called Carbon-14 dating. One of the characteristic of this isotope is that it has a half-life of 5,730 years. This means after an organism has been dead for 50,000 years, there's no enough isotopes to do the test with Carbon-14.

Therefore, the right answer is D.

Write the expressions for the equilibrium constant expressions for K_c, and for K_p, if applicable, for the following processes:
IceJOKER [234]

The equilibrium constant could be found using the relationship Kaq = [H^+] [HCOO-]/HCOOH

<h3>What is the equilibrium constant?</h3>

The equilibrium constant is a value that shows us the extent to which reactants are converted into products. We know that a very high value of the equilibrium constant implies that the reactants are mostly converted into products.

Now we have the equation of the reaction as; HCOOH(aq)⇌H^+(aq) + 〖HCOO〗^- (aq). The equilibrium constant ca now be written in terms of Kaq.

Thus the equilibrium constant is;

Kaq = [H^+] [HCOO-]/HCOOH
