What property would be the most useful in telling hematite and magnetite apart?
The property that would be most useful in telling hematite and magnetite apart is magnetism. Magnetite is strongly magnetic, whereas hematite is not magnetic. This distinction can help differentiate between the two minerals.
What kind of rock did the ancient Chinese use to point to the leading star?
The ancient Chinese used a type of rock called "magnetite" to point to the leading star. Magnetite is a naturally occurring magnetic mineral that aligns itself with the Earth's magnetic field, allowing it to indicate direction. This property made it useful for navigation, as ancient Chinese mariners and travelers could utilize it to locate the North Star, which served as a reliable reference point in the night sky.
A mineral that can act as a magnet?
Magnetite is a mineral that can act as a magnet due to its strong magnetic properties. It is an iron oxide (Fe3O4) and is one of the main ores of iron. Magnetite exhibits ferromagnetism, meaning it can become magnetized in the presence of a magnetic field and retain that magnetism even after the field is removed. This property makes it useful in various applications, including magnetic storage media and compasses.
What property is generally least useful in identifying minerals?
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.

What would happen to travelers relying on a compass if they traveled in an area with a large magnetite deposit?
Travelers relying on a compass in an area with a large magnetite deposit may experience compass interference due to the magnetic properties of magnetite. This could cause the compass to give inaccurate readings, leading travelers to navigate in the wrong direction. To mitigate this issue, travelers should cross-check their navigation using other methods such as landmarks or GPS.
