Final Review Flashcards (Chemistry)

Kinetic Energy
the energy of a body or a system with respect to the motion of the body or of the particles in the system.
chemical energy
Energy liberated by a chemical reaction or absorbed in the formation of a chemical compound.
potential energy
the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Molarity formla
M=moles/L
titration/dilution formula
m1v1=m2v2
according to the law of conservation of mass, the mass of the products (sum) must always _______ the mass of the reactants (parts)
equal
