In: Chemistry
Chemical property describes the ability of a substance to undergo change in identity while physical properties can be observed without changing the identity of the substance.
A. Texture : Change in texture does not change the object,s identity , hence it is physical property.
B. Toxicity : Toxicity is how dangerous a chemical to one's health. Change in toxicity also changes identity of object. Hence chemical property.
C. Conductivity : chemical property. Every substance has its own conductivity.
D. Density : Change in density does not change the identity of the substace. Hence, physical property.
E. Flammability : Flammability is chemical property.
F. Reactivity with other metals : chemical property. Because chemical change occure during reaction with metal.
answer: B, C, E, F
