Physical properties can be . observed. and measured without changing the . identity. of the substance. . Phase. Changes: . Melting. Point: the temperature at which a substance . Because . entropy is a state function, . the property is what it is regardless of pathway, the . entropy change for a given reaction can be calculated by taking the difference between the . standard entropy.

Molecule representation. 2-hydroxypropanoic acid. IUPAC nomenclature. Molecular formula. Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. 2) Change in temperature. Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. Stoichiometry. (identity and relative amounts of reactants and products).. Spontaneity (feasibility of the reaction, based on thermodynamics).. Speed…KINETICS (reaction rates).. Stopping…when will the reaction stop? (Equilibrium-next chapter). All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. .
