Classify the following as a physical property (phys) or a chemical property (chem). (a) Silver metal has a shiny luster. (b) Silver metal has a density of 10.49 gtcm3. (c) Silver metal and chlorine gas produce AgCl. (d) Silver metal has a melting point of 1235 "C. (e) Silver metal conducts electricity. (0 Silver metal gives no reaction in acid.

Explanation:

Hello,

The question above requires us to classify certain properties which may either fall into physical or chemical properties of that matter.

Physical properties are properties which are of intrinsic value and has no influence on the chemical nature of the substance while chemical properties are those that influence the chemical nature of the substance.

Physical properties can be measured or calculated while chemical properties of a substance is very difficult to measure.

a). Silver has a shiny luster is an example of "physical property" because the shiny nature of silver has no chemical importance.

b). Silver metal has a density of 10.49 g/cm³ is also a "physical property" because density is a physical property of a material.

Density is ratio between mass and volume which are both physical properties since they can be measured.

c). Silver metal and Chlorine gas produce Silver chloride (AgCl) is a "chemical property" since it involves combining of two elements and they both lose their original chemical identity after the reaction.

d). Silver metal has a melting point of 1235°C is a "physical property"

e). Silver metal conducts electricity is a "chemical property" since conduction of electricity are done by the availability of mobile electrons in its electron cloud.

f) silver metal gives no reaction to acid is also an example of "chemical property"
