Which of the following is true of the relationships between heat of fusion and heat of vaporization? Using the heat of fusion, you can predict the heat of vaporization.

The heat of vaporization is typically larger than the heat of fusion.

the answer is b & c i believe : )

it is stable as it is in group 0 which have full outer shells of electrons

pv=nrt

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
