classify these as either a chemical property or physical property. matter has many properties. physical properties do not change the composition or chemical nature of the matter. chemical properties represent an ability or inability to undergo a process that does change the composition or chemical nature of the matter. another way to put this is that chemical properties describe the way a substance may change or react to form other substances. distinguishing these is an important skill\n\nchemical property\n\nphysical property\n\nsize reactivity hardness conductivity luster ph viscosity toxicity half - life enthalpy
Answer
Brief Explanations:
Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Chemical properties involve a substance's ability to undergo chemical changes. Size, hardness, conductivity, luster, and viscosity are physical as they don't change the chemical nature. Reactivity, pH, toxicity, half - life, and enthalpy are chemical as they relate to chemical reactions or changes in composition.
Answer:
Chemical Property: Reactivity, pH, Toxicity, Half - life, Enthalpy Physical Property: Size, Hardness, Conductivity, Luster, Viscosity
