What is the order of the minerals from the softest to the hardest?
mohs hardness scale
Why might it be important to know the hardness of different minerals?
in order for us to know how hard we are going to scratch it and the materials used in scratching it. -hoping that i can help! :)
Name the 10 hardest-minerals in order.?
The hardness of minerals is measured using Mohs scale. Minerals are ranked due to their relative hardness from 1 to 10; 1 being the softest, and 10 being the hardest.10 Diamond 9 Corundum 8 Topaz 7 Quartz (porcelain - 7) 6 Orthoclase (steel file - 6.5) 5 Apatite (knife blade or nail - 5, window glass - 5.5) 4 Fluorite 3 Calcite 2 Gypsum (fingernail - 2) 1 Talc.
What is the Mons scale?
A scale for classifying minerals based on relative hardness, determined by the ability of harder minerals to scratch softer ones. The scale includes the following minerals, in order from softest to hardest: 1. talc; 2. gypsum; 3. calcite; 4. fluorite; 5. apatite; 6. orthoclase; 7. quartz; 8. topaz; 9. corundum; 10. diamond. It should be Mohs scale. Anant
How is the Mohs scale of mineral hardness used?
The Mohs scale is used to aid in quick field identification of minerals, along with other techniques. Mohs based the scale on ten minerals that are all readily available. As the hardest known naturally occurring substance, diamond is at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material. For example, if some material is scratched by apatite but not by fluorite, its hardness on the Mohs scale would fall between 4 and 5. Hardness Mineral 1 Talc (Mg3Si4O10(OH)2) 2 Gypsum (CaSO4·2H2O) 3 Calcite (CaCO3) 4 Fluorite (CaF2) 5 Apatite (Ca5(PO4)3(OH-,Cl-,F-) 6 Orthoclase (KAlSi3O8) 7 Quartz (SiO2) 8 Topaz (Al2SiO4(OH-,F-)2) 9 Corundum (Al2O3) 10 Diamond (C)

How does mineralogist identify the hardness of a mineral?
Minerologists identify mineral harness with a variety of tools. In order of hardness, they gnerally use their fingernails, nails, copper pennies, knife blades, glass, porcelain and other minerals such as quartz, topaz, corundum and diamond. The Moh's Hardness Scale gives a list of minerals in order of hardness with talc being the softest with a rating of "1" and diamond the hardest at a "10".

5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
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.
Can a mineral scratch any mineral with a higher hardness?
yes, minerals can only be scratched by other minerals with hardness equal or greater. thus this explains why a diamond can be cut and "polished" by dust or smaller diamonds
What test is most reliable for identifying pyrite and gold?
Mineralogists often use the physical properties of minerals to identify them. The most reliable test in order to identify a mineral is the test for hardness.
Are some tests better than others for identifying certain minerals?
Yes, you can usually identify the mineral salt by its taste. However, with most minerals one would apply a series of tests, eg hardness, flame test, colour, density, streak, shape in order to identify the mineral.

What is the difference between vickers hardness test and brinell hardness test?
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.

The scale includes the following minerals, in order from softest to hardest: 1. talc; 2. gypsum; 3. calcite; 4. fluorite; 5. apatite; 6. orthoclase; 7. quartz; 8. topaz; 9. corundum; 10. diamond.

How do you determine if a water sample is hard or soft?
The Mohs scale of hardness arranges ten common minerals order of increasing hardness and each is assigned a number: 1, talc; 2, gypsum; 3, calcite; 4, fluorite; 5, apatite; 6, orthoclase (feldspar); 7, quartz; 8, topaz; 9, corundum; and 10, diamond. Hardness of minerals is defined as the resistance of the smooth surface of a mineral to scratching. A soft surface is scratched more easily than a hard surface; so a hard mineral, such as diamond, will scratch a soft mineral, such as graphite, and the hard mineral will not be scratched by the soft. Hardness of metals is determined by impressing a small ball or cone of a hard material into the surface to be tested and measuring the size of the indentation. Hard metals are indented less than soft metals. This is known as the Brinell test
