Answer:
The correct answer is "uranium-238".
Explanation:
Uranium-238, is the most abundant isotope of the element uranium. Uranium-238 has not enough nuclear force to balance electrostatic forces between protons, and as a result, it is a radioactive isotope and its losing energy because of the spontaneous breakdown of its atomic nucleus. Uranium-238 has a half-life of 4.5 billion years and is used as fuel in nuclear reactors as well as for dating purposes.
The answer is C. In order to balance this equation you have to look at the 2AlCl3. The first Cl2 needs to equal 6 because 2x3=6. So the answer is 3.
The glass is half empty is an example of non-volume.
I believe the appropriate organization found in both cases would be a population. As a population consists of a single species found within a particular area and capable of interbreeding.
