No.
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.
Yes, graphite is harder than gypsum, so it can scratch gypsum.
Diamond can scratch talc but is not scratched by calcite. Diamond is the hardest mineral on the Mohs scale, making it capable of scratching minerals with a lower hardness, like talc.
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
Halite can scratch gypsum.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
A diamond can scratch a diamond, but one diamond cannot scratch itself.
Gypsum is the softest mineral among diamond, quartz, silver, and gypsum. It has a hardness of 2 on the Mohs scale, while diamond is the hardest with a rating of 10.
No. Only a diamond can scratch another diamond.
You can tell what Topaz can scratch by looking at the Moh's Scale of Hardness. It looks at ten well known, easily available minerals, and arranged them in order of their "scratch hardness". If a specimen to be tested can be scratched by a known mineral from the list, it is softer than that mineral. If it in turn will scratch another known mineral, it is harder than that mineral. Topaz is ranked an 8 and therefore can scratch everything lower than an 8. This includes quartz, feldspar, apatite, calcite, gypsum and talc.
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.
Nope! A diamond is the hardest substance on earth so only a diamond can scratch a diamond!
