Final answer:
The statement that is not true about hematite is that its composition contains iron and sulfur. Hematite is essentially iron (III) oxide and lacks sulfur. It displays properties typical of iron ores, such as conductivity and a red-brown streak.
Step-by-step explanation:
The statement about hematite that is NOT true is that "Its composition contains iron and sulfur". Hematite is an iron ore composed primarily of iron (III) oxide (Fe2O3), and it does not contain sulfur in its composition. Its appearance can be metallic or earthy (a), and it has a characteristic red-brown streak when scratched on a porcelain plate (c).
Hematite is indeed an ore of iron (d), as it is a primary source of iron for the steel industry.
Iron is a metal because it is solid, shiny, and conducts electricity and heat well (13). Metals like iron are typically shiny, malleable, ductile, and good conductors of electricity and heat, whereas nonmetals have varying characteristics and generally do not conduct as well (15).
