Assignment Classifying Physical and Chemical Properties Define physical property Define chemical property Explain how a physical property is different than a chemical property. List 10 Physical Properties 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. List 3 Chemical Properties 1. 2. 3. 4. Chemical Formula ex. H₂O Directions: Classify the following examples as a chemical or physical property. a. a substance changes from a liquid to a gas at 276 C b. a substance will create a gas when put in an acid. c. a substance is a good electrical conductor d. a substance will explode when ignited with air. e. a substance is colorless and liquid. f. a substance exposed to oxygen turns a greenish color. g. a substance sparks in water. h. a substance is has luster and is malleable.
Directions: Classify as physical or chemical property, then choose all properties that apply for underlined parts. 1. Calcium carbonate is a white, solid that sinks in water: 2.71 g/cm³. c. color d. luster e. state of matter f. reactivity g. density 2. Sodium like most metal combines with non-metals. For example, Chlorine bonds with sodium to form table salt. c. flammability d. odor e. conductivity f. reactivity g. density 3. Ethanol burns in air. b. odor d. flammability e. state of matter f. reactivity g. volume 4. Sodium is a silvery white, shiny metal that can be pounded into a sheet. c. color d. luster e. malleable f. ph g. density 5. The Statue Liberty was made out of brownish orange cooper because it was easy to pound and hammer into the shape of Lady Liberty. c. color d. luster e. ductility f. reactivity g. malleable 6. Calcium carbonate produces carbon dioxide when combined with acid c. ph d. luster e. malleable f. reactivity g. ductility 7. Ethanol is a colorless, liquid. c. color d. viscosity e. state of matter f. ph g. mass 8. When first made Lady Liberty was made out of cooper but after years of exposure to oxygen and water in the air the statue has tarnished (turned a green) c. state of matter d. luster e. color f. reactivity g. density
List 10 Physical Properties State of matter Flexibility Color, Clarity elasticity Shape Hardness Luster hardness Malleable Ductile Conductivity taste Metal/Non Metal texture Mass Crystal form Volume Density Melting, boiling and freezing point Odor size temperature viscosity List 4 Chemical Properties Flammability Reactive Acid/Base Chemical Formula Classify the following as either chemical or physical properties of a substance. a. a substance has a melting point = 276 C Physical, melting point b. a substance will create a gas when put in an acid. Chemical, reactive, acid/base c. a substance is a good electrical conductor physical conductivity d. a substance will explode when ignited with air. Chemical reactive, flammable e. a substance is colorless and liquid. Physical color, state of matter f. a substance exposed to oxygen turns a greenish color. Chemical reactive g. a substance sparks in water. Chemical reactive, flammable h. a substance is a metal. Physical metal Identify each of these characteristics as physical and chemical properties. 1. Calcium carbonate is a white, solid with a density of 2.71 g/cm3. It produces carbon dioxide when combined with acid Physical property: color, state of matter, density Chemical property: reactive 2. Sodium is a silvery white, metal. Sodium like most metal combines with non-metals. For example, Chlorine bonds with sodium to form table salt. Physical property: color, metal Chemical property: reactive
3. Ethanol is a colorless, liquid. Ethanol burns in air. Physical property: color, state of matter Chemical property: reactive, flammability
