The heat of formation formula, also known as enthalpy of formation, is a concept in chemistry that defines the total amount of energy absorbed or evolved as heat when one mole of a substance is formed from its constituent elements.
Imagine you're building a Lego tower. You start with individual blocks (elements) and end up with a completed structure (compound). The process requires energy - maybe you have to push some pieces together harder, or take breaks because your hands get tired. This is similar to the heat of formation - it's the energy required to create a compound from its individual elements.
Enthalpy: A thermodynamic quantity equivalent to the total heat content of a system.
Exothermic Reaction: A chemical reaction that releases energy by light or heat.
Endothermic Reaction: A process or reaction in which the system absorbs energy from its surroundings in the form of heat.
