5 True/False questions
Enthalpy of reaction → the change in enthalpy for a reaction
Hess's Law → energy that is in the process of flowing from a warmer object to a cooler object.
Thermochemistry → the study of heat changes that accompany chemical reactions and phase changes
System → energy that is in the process of flowing from a warmer object to a cooler object.
Standard enthalpy of formation → heat required to melt one mole of a solid substance
