Why is oxygen teeth and honey not a mineral?
A mineral must follow a certain criteria. It has to be naturally occurring, generally inorganic homogeneous solid with a crystalline structure and a definite (but not fixed) chemical composition. Water cannot be a mineral because it is a liquid. Honey cannot be a mineral because it is a liquid and is organic Oxygen cannot be a mineral because it is a gas. Teeth cannot be a mineral they are organic. Ice, however, can be a mineral if it is formed naturally. Ice forming on your windshield is a mineral but ice from an ice cube tray is not a mineral.
Which is an example if a mineral whose streak cannot be determined with a porcelin streak plate?
Hematite, gold, feldspar or magnetite
What mineral property cannot be used to identify a mineral?
Mass
Why can you determine the identity of a mineral by showing what it cannot be?
Determining the identity of a mineral by showing what it cannot be relies on the process of elimination, where specific properties are assessed to rule out potential candidates. By testing characteristics such as hardness, luster, color, streak, and cleavage, one can narrow down the possibilities. If a mineral fails to meet the defining criteria of known minerals, it can be effectively excluded from consideration, thereby clarifying its identity through contrast. This method leverages the unique combination of properties that distinguish one mineral from another.
What is mineral water?
Mineral water is rain water that fell as distilled water, then drained into the ground where it dissolved out some of the minerals that are in the rocks. i.e. it became "mineralised" or polluted by, or contaminated by the ground minerals present in that area which can include poisons such as arsnic and cadmium. All bottelled mineral water should be checked for toxicity, read the label. You cannot beat rain water for drinking.
What mineral cannot be scratched by another mineral?
A diamond. Actually, a diamond can be scratched my other minerals.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
What mineral can only be scratched by one mineral?
Diamond is the hardest mineral and can only be scratched by another diamond.
Is fluorite harder than calcite?
Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.
What mineral cannot be scratched by anything but quartz?
There is none because diamond is at the top of the scale so it can scratch anything.
Which mineral ranked the highest hardness?
A diamond is the hardest mineral. A diamond can scratch all other minerals or rocks and cannot be scratched by another mineral or rock except another diamond.
What minerals can a steel knife scratch?
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
Which mineral cannot scratch any mineral by itself?
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
What mineral can scratch itself but no other mineral can scratch it?
A diamond is the only material that cannot be scratched by any other than itself.
Can hornblende be scratched from a fingernail?
Hornblende is a mineral with a hardness of about 5 to 6 on the Mohs scale, which means it is harder than a fingernail, which has a hardness of about 2.5 to 3. Therefore, hornblende cannot be scratched by a fingernail. Instead, a fingernail would likely be scratched by hornblende if they came into contact.
What mineral has no clevage and cannot be scratched with a steel file?
The mineral that has no cleavage and cannot be scratched with a steel file is typically quartz. Quartz is known for its hardness, ranking 7 on the Mohs scale, which means it can only be scratched by harder materials. Its lack of cleavage results in conchoidal fractures, giving it a distinctive break pattern. Other minerals with similar characteristics may include certain varieties of garnet or tourmaline, but quartz is the most commonly referenced.
Can apatite be scratched by quartz?
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
