Iron, Fe, is a solid at room temperature. Iron is a shiny, bright white metal that is soft, malleable, ductile and strong. Its surface is usually discolored by corrosion, since it combines readily with the oxygen of the air in the presence of moisture. The density of iron is 7.86 g/cc. Iron is a good conductor of electricity and heat. Consider the paragraph above. What is one chemical property of iron? A) Iron is malleable. B) The density of iron is 7.86 g/cc. C) Iron combines readily with oxygen. D) Iron is a good conductor of electricity and heat.

Know the Answer?

Sara · Answer 1

C) Iron combines readily with oxygen.

Explanation:

A physical property can be measured and observed without changing the composition or identity of the substance; while a chemical property is observed when a chemical change is given, such as a reaction.

So, the only statement that implies a chemical change is the rapid combination of iron with oxygen, forming an oxide which is a new substance.

Haylee Zavala · Answer 2

The correct answer is option C. Iron combines readily with oxygen is the chemical property of iron.

The chemical property of iron is revealed when it reacts with oxygen of the air in the presence of moisture in a chemical reaction to form iron oxide or rust.

Rust corrodes and discolors the shiny, bright white iron metal.
