Combustion and Enthalpy of FOrmation

IQ2: How much energy does it take to break bonds, and how much is released when bonds are formed?

Students:

● investigate Hess’s Law in quantifying the enthalpy change for a stepped reaction using standard enthalpy change data and bond energy data, for example:

– carbon reacting with oxygen to form carbon dioxide via carbon monoxide

● apply Hess’s Law to simple energy cycles and solve problems to quantify enthalpy changes within reactions, including but not limited to:

– heat of combustion
