Answer:
Explanation:
The solid consists of positive and negative ions, so it is an ionic solid.
Ionic solids are brittle, usually water-soluble, and poor thermal conductors as solids. Thus, the correct answer is .
(A) is wrong. It describes a covalent solid, which is soft and always a poor conductor.
(B) is wrong. It describes a covalent solid, which is also low-melting.
(D) is wrong. It describes a metal, and a metal does not contain negative ions.
Answer:
See figure 1
Explanation:
In this question, we have to remember that each <u>carbon has 4 electrons</u> and each <u>hydrogen has 1 electron</u>. Additionally, the structure proposed have to have <u>8 electrons for each atom</u> <u>(except hydrogen)</u>. With this in mind, we need to have a <u>double bond</u> between the carbons, because in this arrangement each carbon would have 8 electrons <u>(octet rule)</u>.
See figure 1
I hope it helps!
