Answer:
C. It has no delocalised electrons and each carbon atom forms four covalent bonds with other carbon atoms.
Explanation:
- Diamond is composed solely by carbon atoms. As the difference of electronegativity between atoms is 0, diamond is a <em>fully covalent compound</em>.
- The lack of electrical conductivity stems from a<em> lack of available electrons</em>, this means that there are no delocalised electrons.
The information in the first point discards options A and D, while the second point discards option B. Thus the answer is option C.
Percent yield is 108.3%
<u>Explanation:</u>
Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,
Percent yield =
It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,
Percent yield =
So the percent yield is 108.3%.
I think the answer is a molecule
Loess, which can be carried by wind over long distances.
