5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.

Can you scratch plaster with a fingernail?
It would depend on how loosely the sandstone was cemented. Some sandstone can be crumbled in your clenched fist, and some are extremely hard.
What is gypsm?
Gypsum is a mineral, with the chemical formal CaSO4(H2O)2. It is soft and is an index mineral for Moh's Hardness Scale, with a hardness of 2. It is softer than a fingernail. It is in the monclinic crystal system and is commonly used in agriculture, manufacture of ceramics and sheet rock.
Moh's scale identifies minerals by their relative?
The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. Ithardnesses
What is the scale called to measure hardness of gemstones?
The Mohs scale. # Talc # Gypsum # Calcite # Fluorite # Apatite # Feldspar # Quartz # Topaz # Corundum # Diamond The Mohs scale, however, is an purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is almost four times as hard as corundum. Check the related link for more info.
A minerals hardness with respect to other minerals can be determined by?

What mineral that can scratch gypsum but cant scratch calcite?
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
What is the hardness of a mineral that scratches gypsum?
The mineral that scratches gypsum has a hardness greater than 2 on the Mohs scale. Gypsum has a hardness of 2 on the Mohs scale, so any mineral that can scratch it must have a hardness greater than 2.
Does gypsum scratch flourite?
No. Gypsum has a hardness on the Mohs scale of 2. Topaz has a hardness on the Mohs scale of 8. This means that topaz ranks much harder than gypsum and that gypsum cannot scratch topaz. Please do not refer to these numbers as absolute hardness. This does not mean that topaz is 4 times as hard as gypsum since they are ranked 8 and 2. The Mohs scale only designates a hardness scale of 1 through 10 so that geologists and mineralogists in the field have a quick way of determining a mineral's identity or eliminating possible options of what the mineral may be.
Which mineral has a hardness of 2?
Gypsum is the mineral listed at 2 on the Mohs hardness scale.
What can scratch gypsum but can be scratched by all other minerals?
Talc can scratch gypsum, but can be scratched by all other minerals. Talc is the softest mineral on the Mohs scale, with a hardness of 1, making it easily scratched by minerals with higher hardness values. Gypsum has a Mohs hardness of 2, so talc can leave a mark on it.
Which mineral has the same hardness as fingernails?
The mineral that has a similar hardness to fingernails is gypsum. Gypsum has a Mohs hardness of around 2 on the scale, similar to that of fingernails.
What are the two minerals that you can scratch with a fingernail?
Talc and gypsum are two minerals that can be scratched with a fingernail due to their low hardness on the Mohs scale.
What mineral would halite be able to scratch?
Halite can scratch gypsum, which has a Mohs hardness of 2.5 on the Mohs scale. Halite has a hardness of 2.5, so it can scratch any mineral with a hardness lower than 2.5.
What is the hardnessof a mineral that scratches the gypsum but can't scratch fluorite?
Between 2 and 4. Calcite, which has a hardness of 3, is one example.
What mineral scratches quartz but not gypsum and is green in color?
The mineral that scratches quartz but not gypsum and is green in color is called fluorite. It has a hardness of 4 on the Mohs scale, making it capable of scratching quartz (hardness of 7) but not gypsum (hardness of 2). Fluorite is commonly found in various shades of green, but it can also occur in other colors such as purple, yellow, and blue.
Can Gypsum can scratch diamond?
No, gypsum cannot scratch diamond. Diamond is the hardest mineral on the Mohs scale with a rating of 10, while gypsum is much softer with a rating of 2, which means diamond is able to scratch gypsum but not the other way around.
What minerals can steel file scratch?
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
