Thermochemisty Flashcards
Thermochemistry
Stoichiometry including heat energu
Heat
The flow of energy
Temperature
Measurement of average kinetic energy
Enthalpy
Energy in a system
/\ H
Change in enthalpy
Joule/ calorie
Used to measure energy
Exothermic
Energy in released, more energy in reactants, -/\H
Endothermic
Energy is absorbed, +/\H, less energy in reactants
Precipitate
The formation of a solid in a liquid
Reactants
Left side of equation, what goes in
Products
Right side, what comes out
Exothermic, difference of energies in reactants and products
More energy is released in formation if bonds than needed to break bonds. Extra energy released
Endothermic, difference of energies between reactants and products
More energy require to break bonds then released to form, absorbs energy to make up for it
