The capability of a substance to be stretched into thin wires without breaking is known as — A malleability
B conductivity
C luster
D ductility

The answer is D, ductility

Explanation:

The definition of ductile is "(of a metal) able to be drawn out into a thin wire."

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

c is the answer because when something is left after something evaporates that shows the chemical change.
