A good chemical test to determine the primary mineral in limestone is the acid reaction test. Limestone primarily consists of the mineral calcite, which reacts with dilute hydrochloric acid to produce bubbles of carbon dioxide gas. This effervescence confirms the presence of calcite as the primary mineral in limestone.
The resistance of a mineral to scratching is measured using the Mohs scale of mineral hardness. This scale ranks minerals from 1 (softest) to 10 (hardest). The resistance to scratching is determined by testing the mineral's ability to scratch or be scratched by another mineral on the scale.
If your cat is wearing a collar TAKE IT OFF have her checked out at a vet, she may be allergic to something or maybe she/he has fleas and do not let your cat outside, it will take 5 years off a cat's life.

One could purchase a used cat scratching post at a flea market, yard sale, or a swap meet. One could also check the classified advertisements in their local newspaper.

Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
Mineral hardness is tested on a glass plate or usually a finger nail.
It is called a streak and its purpose is to find the hardness of the mineral.
The Moh's scale is used to test the hardness of a mineral. It will be tested by a fingernail scratching it.
False. The streak test is not a test of mineral density but is used to determine the color of a mineral in powdered form by scratching it on a ceramic plate.
Most likely you would be testing to see if the mineral was harder or softer than the nail.
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
no is not a mineral
The color of a mineral's powder found by scratching the mineral on a white tile is referred to as the mineral's streak color.
