10. In the classroom setting, coffee cup calorimeters are very useful in exploring systems with small energy changes. However, some experimental assumptions must be made when using these calorimeters. Explain what these assumptions are. [3] There are many assumptions suchas: 11. The enthalpy of formation for Benzene, C6H6x is 49.0kJ/mol. Represent this thermochemical reaction as: [3] a. a thermochemical equation with an energy term b. a thermochemical equation with a H value, and c. a potential energy diagram
