### Enthalpy of formation vs. heat capacity

Are these two concepts related? Are they opposites of each other, or are they two completely separate things?

Specific heat capacity is the amount of energy needed to raise the temperature of 1g of a substance by 1C. The standard enthalpy of formation, however, is the change in enthalpy when one mole of a substance is formed from its pure elements.

heat capacity is the energy required to raise temp of a substance which is much different from the energy change from forming a bond. These are separate ideas as one deals with change in temp and phase of a substance and the other is chemical changes to the substance
