Does talc or graphite have more metallic luster advances?
Graphite has more metallic luster properties compared to talc. Graphite has a greasy feel, excellent conductivity, and metallic luster properties due to its layered atomic structure, whereas talc has a pearly luster and is not a good conductor of electricity.
A human fingernail has a hardness of approximately 2.5 Which two minerals are softer than a human fingernail?
Talc and gypsum are two minerals that are softer than a human fingernail. Talc has a hardness of 1 on the Mohs scale, while gypsum has a hardness of 2.
The mineral talc is soft enough to leave a streak on paper and is commonly used in?
Talc is commonly used in cosmetics, such as baby powder and face powder, due to its softness and ability to absorb moisture. It is also used in industrial applications for its lubricating and anti-stick properties.
Name the hardest and softest substances occurring in nature?
diamond is the hardest and graphite is the softest
What are 2 minerals that can be scratched by a fingernail?
Quartz (Mohs 7.0) and diamond (Mohs 10,0) are two of many minerals that are harder than copper (Mohs 2.5-3.0).
Does talc or graphite have more metallic luster advances?
Graphite has more metallic luster properties compared to talc. Graphite has a greasy feel, excellent conductivity, and metallic luster properties due to its layered atomic structure, whereas talc has a pearly luster and is not a good conductor of electricity.
Is talc graphite?
No, talc is not graphite. Talc is a mineral composed mainly of magnesium, silicon, and oxygen, characterized by its softness and greasy feel, often used in talcum powder and cosmetics. Graphite, on the other hand, is a form of carbon known for its layered structure, electrical conductivity, and use in pencils and lubricants. While both are naturally occurring minerals, they have distinct chemical compositions and properties.
What are some minerals?
Amethyst ,Graphite, talc, calcite, corrundum, flourite, ruby, etc.
What is a Metamorphic rock containing minerals such as talc and mica and quartz or graphite called?
schist
Are there any minerals softer than talc?
There are no other minerals that are softer than talc. On Moh's hardness scale, diamonds are the hardest mineral, and talc is the softest mineral in the world.
A human fingernail has a hardness of approximately 2.5 Which two minerals are softer than a human fingernail?
Talc and gypsum are two minerals that are softer than a human fingernail. Talc has a hardness of 1 on the Mohs scale, while gypsum has a hardness of 2.
Why mineral such as graphite and talc are so soft?
The most probable explanation is the specific structure of grouped crystals - a lamellar type.
What if you had two white samples of talc and gypsum how could you tell them apart?
Gypsum is soluble in water - Talc isn't
What is a good slogan for a ad for talc?
Talk about talc!
Is talc a form of carbon?
No, talc is not a form of carbon. Talc is a mineral composed primarily of magnesium, silicon, and oxygen, with the chemical formula Mg3Si4O10(OH)2. It is a hydrated magnesium silicate and is known for its softness, often used in talcum powder and various industrial applications. Carbon, on the other hand, is a distinct element with different properties and forms, such as graphite and diamond.
Have mineral crystals arranged in bands?
Yes. The most extreme examples of this would be the micas, and perhaps graphite. You may like to check whether talc also has this character.
The mineral talc is soft enough to leave a streak on paper and is commonly used in?
Talc is commonly used in cosmetics, such as baby powder and face powder, due to its softness and ability to absorb moisture. It is also used in industrial applications for its lubricating and anti-stick properties.
