Describe how to find the hardness of unknown mineral?
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.
Can you test the hardness of chicken bones before and after they're soaked in liquid?
You certainly can test the hardness of chicken bones before and after they are soaked in liquid. You can try tapping and bending them for example.
What is a non example of calcium?
Wind is a non example of calcium.
Why can't non metals be scratched?
It depends on which non metals you mean. The ability to scratch a material depends on its hardness relative to the material you use to scratch it with. With your nails you can scratch materials softer than your nails, like some plastics and minerals. But nothing can scratch in diamond because it's the hardest material there is, but in turn diamond can scratch all other materials, since they're softer that diamond including all metals and non metals. So although most metals are relatively soft, there are many non metals that are softer that some metals. Trivia: the softest metal is mercury with a hardness of 0 (it's liquid at room temperature) The hardest metal is carbon steel with a hardness of around 8 to 9 The softest mineral is talc with a hardness of 1 The hardest mineral is diamond with a hardness of 10 (a form of pure carbon)
