D. C₄H₁₀ and C₂H₅
<h2>
What is a empirical formula?</h2>
A chemical formula indicating the elements of a compound and their relative proportions, as (CH₂O)n.
Since an empirical formula indicates the ratio (proportions) of the elements in the compound, it can be used, along with the molar weight of the compound, to determine the molecular formula.
The empirical formula provides the smallest whole-number ratio among elements or compounds within a molecular compound. A compound is a chemical formed from atoms of different chemical elements.
Hence, Option D is correct.

<span>Molds are created to achieve a
specific design of a material. These materials either came from a process of
having a higher or lower temperature. Therefore, the molder must have thermal
resistant properties. Low melting points means that the material to be shaped
came from a cooler process. Wood and metal have higher thermal conductivity and
therefore can easily be cooled. The wax can turn really hard and can be
unbreakable when present in colder materials due to the lipids present in it. Clay
however can become a mold because of its low melting point.</span>
Yes it is a pure substance
The nuclear fission process of the power plant bombards the uranium element with a neutron to start a series of reactions to release a large amount of energy. Thus, option B is correct.
<h3>What is nuclear fission?</h3>
Nuclear fission is a process of generating energy by the collision of the neutron particle with the element. The element under collision splits and releases more neutrons.
As the neutrons are produced they collide with more elements resulting in more energy. It is used to convert water into steam and generate electricity.
Therefore, option B. the neutron collides with elements to produce energy in a nuclear power plant.
