Hailey the answer is D.
Explanation:
if liquid to solid is exothermic then then the other way around would be endorhermic
There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:
Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.
It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.
Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.

Explanation:
the physical and chemical properties of an element are periodic functions of their atomic number.
An electron because that is the only part able to be lost or gained without nuclear action needed
