Document Summary
Chemical change: formation of one or more new chemical substances with a distinct composition; change in the net amounts of some chemical species. Physical properties: color, state of matter, electrical conductivity. When chemical reactions occur in closed environments, the total mass of the system before and after the process remains constant. Chemical reactions occur at varying speeds; the speed is dependent on temperature, pressure, and concentration of the reacting species. Assumption 1: chemical reactions are processes in which the particles that make up the reactants are rearranged. As a result of these rearrangements, substances with a different chemical composition are formed. Assumption 2: rearrangement of atoms during a chemical reaction involves electron redistribution among different atoms. As a result of this process, the internal potential energy of particles in the system changes. Internal potential energy: the energy associated with the internal interactions and movement of the electrons that make up the particles.
