5 Multiple choice questions
- states that if you can add two or more thermochemical equations to produce a final equation for a reaction, then the sum of the enthalpy changes for the individual reactions is the enthalpy change for the final reaction
- energy that is in the process of flowing from a warmer object to a cooler object.
- balanced chemical equation that includes the physical states of all reactants and products, and the energy change, usually expressed as the change in enthalpy
- the change in enthalpy for a reaction
- heat content of a system at a constant pressure.
5 True/False questions
Law of Conservation of Energy → in any chemical reaction or physical process, energy can be converted from one form to another, but it is neither created nor destroyed
Specific Heat → energy that is in the process of flowing from a warmer object to a cooler object.
Molar Enthalpy of vaporization → heat required to melt one mole of a solid substance
Thermochemistry → the study of heat changes that accompany chemical reactions and phase changes
Energy → measure of the disorder or randomness of the particles that make up a system
