Which uses of iron are due to its chemical properties? Check all that apply.

producing colored sparks in fireworks changing from liquid to gas at 2,862°C
rusting in the presence of water and oxygen
changing from solid to liquid if heated to 1,538°C
conducting electricity and heat

Respuesta :

Answer: producing colored sparks in fireworks and rusting in the presence of water and oxygen

Explanation: Chemical properties are properties which involve change in chemical composition of substances.

Rusting is oxidation of iron to ferric oxide.

[tex]Fe+O_2+H_2O\rightarrow Fe_2O_3.xH_2O[/tex]

Colored sparks are produced when hot iron reacts with oxygen in the presence of oxygen.

Changing from liquid to gas at 2,862°C: It represents a physical change as there is no change in chemical composition.

Changing from solid to liquid if heated to 1,538°C:  It represents a physical change as there is no change in chemical composition.

Conducting electricity and heat: It represents a physical change as there is no change in chemical composition.
