Which phrase describes carbon-14 dating? uses the rate at which nitrogen-14 decays into carbon-14 dates the remains of organisms to determine when they died measures the number of unstable elements in ancient volcanic rocks determines the age of ancient fossils older than 50,000 years old

Carbon-14 dating is described as "a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon".

With that in mind, I think out of the four choices, your best bet is "B. dates the remains of organisms to determine when they died".

The answer is B

Explanation:

b. th3 n4zc4 pl4t3 15 c0nv3rg1ng w1th the s0uth 4m3ric4n pl4t3.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
