What is the hardness of calcite on the MOHS hardness scale?
No one seems to know how hard scandium is on the mohs hardness scale (believe me i looked everywhere and they all say N/A) but i did manage to find it's hardness on the Brinell hardness scale. On the Brinell hardness scale it is 750 MPa. If you find how hard it is on the mohs scale please revise my awnser to also include that.
What is the hardness of promethium on the mohs scale?
Mercury's hardness is listed as '0' on interpretations of the Mohs scale.
Which rock is the hardest granite or chalk?
Chalk is a sedimentary rock composed primarily of Calcium Carbonate. Calcium carbonate is also the number one mineral at the Marble spec. Hardness of Chalk is around 3 Mohs. Granite stay at the number 7 at the Mohs scale and Granite is harder than Marble. Granite is mostly composed by feldspat (christal).
What is the hardness of Flint according to the mohs scale of hardness?
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
Is chalk harder than rubber?

Explain why blackboards are not scratched by chalk but are scratched by the sand embedded in the chalk?
The hardness of sand is higher.
Is bedrock hard?
Bedrock could vary in hardness from chalk to granite.
What is a penny on Mohs hardness scale?
A penny has a Mohs hardness of around 3.5. This means that it can be scratched by harder materials like glass or quartz, but it can scratch softer materials such as chalk or talc.

What physical properties could you use to tell the difference between chalk and snow?
Snow is cold Chalk tastes bad.
Is chalk a hard or a soft rock?
Chalk is a hard rock, with large lines of weakness so will erode by physical weathering and the sea.
Explain Why blackboards are not scratched by chalk but by the sand embedded in the chalk?
Blackboards are typically made of a material that is softer than chalk, such as slate or porcelain. When you write on a blackboard with chalk, the friction between the chalk and the board causes the chalk to wear down and leave behind tiny particles of sand or abrasive material embedded in the chalk. These abrasive particles then scratch the surface of the blackboard as you write, creating marks that can be difficult to erase.
