Marginally. Halite has a hardness of 2 to 2.5, about the same as a fingernail.
Halite is hard. It can be scratched by a steel file and a knife with difficulty
Halite has a hardness of 2-2.5 on the Mohs scale of mineral hardness. This means it is relatively soft and can be easily scratched with a fingernail or a copper coin.
Not very. Halite has a Mohs hardness of 2.5.
Magnatite is the mineral that has a nonmatallic luster, is black, and can be scratched by a fingernail.
Talc (1 on the Mohs Hardness Scale) can be scratched by a fingernail.
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.
Halite is hard. It can be scratched by a steel file and a knife with difficulty
Halite has a hardness of 2-2.5 on the Mohs scale of mineral hardness. This means it is relatively soft and can be easily scratched with a fingernail or a copper coin.
Halite, also known as rock salt, has a hardness of 2.5 on the Mohs scale. It is a relatively soft mineral that can be easily scratched with a fingernail or a copper penny.
Not very. Halite has a Mohs hardness of 2.5.
Calcite typically effervesces in acid, whereas halite and gypsum do not. Halite is salty to taste, while gypsum is softer and can be scratched with a fingernail. Also, halite forms cubic crystals, while gypsum forms tabular crystals.
Halite, also known as rock salt, has a hardness of 2-2.5 on the Mohs scale. It is a relatively soft mineral that can be easily scratched with a fingernail or a pocket knife.
Hornblende is a mineral with a hardness of about 5 to 6 on the Mohs scale, which means it is harder than a fingernail, which has a hardness of about 2.5 to 3. Therefore, hornblende cannot be scratched by a fingernail. Instead, a fingernail would likely be scratched by hornblende if they came into contact.
Magnatite is the mineral that has a nonmatallic luster, is black, and can be scratched by a fingernail.
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
Talc (1 on the Mohs Hardness Scale) can be scratched by a fingernail.
Talc i assigned a hardness of 1 according to the Mohs scale of hardness. This implies that talc has the least hardness and therefore is soft and can be scratched by a fingernail.
