Q1. What is Heat of formation
Ans. 
Heat of formation is the energy released or absorbed when one mole of a compound is formed from its elements in their standard states.
• Heat of formation is also known as standard enthalpy of formation.

• It is typically measured in units of kJ/mol.

• Negative heat of formation indicates exothermic reaction, while positive heat of formation indicates endothermic reaction.

• For example, the heat of formation of water (H2O) is -28
