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.

Determine the ratio of amount NaOH reacting per unit amount FeCl3. Enter an integer that represents x mol NaOH/1 mol FeCl3.

earnstyle [38]

Answer is: the ratio of amount NaOH reacting per unit amount FeCl₃ is 3 mol NaOH /1 mol FeCl₃.

Balanced chemical reaction:
3NaOH(aq) + FeCl₃(aq) → 3NaCl(aq) + Fe(OH)₃(s).
NaOH is sodium hydroxide.
FeCl₃ is iron(III) chloride.
Coefficient for sodium hydroxide is three and for iron(III hydroxide is one.

Answer:

The correct answer is 4

Explanation:

Boron trifluoride (BF₃) has a molecular geometry (as shown in the image in the question) referred to as trigonal planar; this is because each of the the fluorine atoms/molecules (bonded to the central boron atom) is placed in such a way that they form the three "end points"/"domains" of an equilateral triangle. Hence, the correct option is the last option.
