Which mineral can be scratched by a steel nail?
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
Can sandstone be scratched by a nail?
Yes, sandstone can be scratched by a nail. Sandstone typically has a hardness of around 6 to 7 on the Mohs scale, depending on its composition, which means it can be scratched by materials that are harder, such as steel. Since a typical nail is made of steel, it can easily scratch the surface of sandstone.
Can halite be scratched by a nail?
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
Which physical property would be best to use to distinguish hematite from the other mineral?
One physical property that can be used to distinguish hematite from other minerals is its streak color. Hematite typically leaves a reddish-brown streak when scratched against an unglazed porcelain plate. This can help differentiate it from other minerals that may have different streak colors.
Does hematite have a streak?
Yes, hematite does have a streak. When scratched against a hard, rough surface, hematite leaves a reddish-brown streak due to the presence of iron oxide in its composition.
Can lead be scratched by a nail?
Yes.
Which mineral can be scratched by a steel nail?
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
Can sulfur get scratched by a nail?
No, sulfur is harder than a nail so it cannot be scratched by a nail. Nails are typically made of iron, which is softer than sulfur. Therefore, if a nail comes into contact with sulfur, the nail is more likely to scratch than the sulfur.
Can sandstone be scratched by a nail?
Yes, sandstone can be scratched by a nail. Sandstone typically has a hardness of around 6 to 7 on the Mohs scale, depending on its composition, which means it can be scratched by materials that are harder, such as steel. Since a typical nail is made of steel, it can easily scratch the surface of sandstone.
Can halite be scratched by a nail?
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.
Can feldspar be scratched by a nail?
Yes. It is much harder than your fingernail.
Can diamonds be scratched with a nail?
No. Only another diamond can scratch a diamond.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
Can nickel be scratched by a nail?
Yes, nickel is softer than steel, so it is possible for a nail to scratch nickel.
Can sulfur be scratched by a nail?
No, sulfur cannot be easily scratched by a nail because it is a relatively soft material compared to metals like iron or steel. Sulfur has a Mohs hardness of 1.5–2, while iron nails typically have a hardness of 4-5 on the Mohs scale.
Can talc be scratched by a steel nail?
Yes, because talc is very soft.
