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! :)

What is the luster streak and hardness of a geode?
Its simple, see a lot of people would have guessed a geode is a mineral or a gem. But its not. Geode is a sedimentary rock so instead of looking for the luster steak and hardness look facts on it like from its sedimentary form. A geode might have minerals in it, but that doesn't make it a mineral itself.
What property might you test by rubbing one mineral directly against another mineral?
hardness
What are some non-minerals you might find contained in rocks?
There are many non-minerals you might find contained in rocks include gypsum. You might also find non-minerals like halite and calcite.
Name 2 tests you can determine what minerals a rock is made of?
While a precise mineralogy of a rock can be determined via optical petrography or X-ray Defractometry (XRD). two simple test that you can perform in a classroom lab are acid tests and scratch tests.Different minerals will dissolve in different acids. before the advent of spectrometry, many geologist would painstakingly dissolve rocks one mineral at a time to estimate their relative abundances. Dilute hydrochloric acid, or sometimes even vinegar, can cause certain carbonate baring rocks to bubble or fizz. This would imply the presence of Calcite, a calcium carbonate mineral, found commonly in schools in the form of chalkDifferent minerals will also have different hardnesses. while this is rarely completely diagonal, this difference does help to narrow down possible minerals in a rock. if you can scratch a rock with just your fingernail, it is much softer than a rock that can scratch metal or glass. rocks hardnesses are classified on the Mohs scale from 1 to 10, 1 being the softest, might be talc (the source of talcum powder) while a 10, the hardest, might be a diamond. The are numerous kits available, including sample minerals and scratch plates, in order to test and compare a minerals hardness.For example, if you found a white clear crystal, it might be difficult to tell just by looking at it if it were calcite or quartz. However if you could scratch it with something made of steel, like a nail. you would know that it has to have a hardness of less than 4. quartz has a hardness of 7, while calcite has a hardness of 3. If you had to pick between the two, calcite is probably the answer, and you could further test it by seeing if a drop of dilute acid makes it bubble.
Why might a geoligest aks an analytical chemist to identify the minerals in a rock?
they might want a second appinion

If a human lacks minerals what happens?
you might have sickness if you lack minerals. you might be malnourished

How can you recognize that granite is a mixture of different materials?
you can see the different bits and pieces of the rock
What is an advantage that alloys might have or many pure metals?
Some advantages are: increased hardness, resistance to corrosion, better workability, improved mechanical properties, improved or different aspect, etc.
Each mineral has a different formation?
Indeed, each different mineral has a different chemical composition and crystal structure. Sometimes you may have two minerals with the same chemical formula, but which differ in their crystallography. Calcite and Aragonite would be one example. Similarly several different minerals might form face-centred cubes, but differ in their chemistry.
What is the general shape of a mineral?
There is no general shape of a mineral. Each mineral has its own shape, even though two different minerals might have the same shape. A few examples of shapes of minerals are: Rhomboid, rock, and cubic.
What happens when a diamond is hit by a bullet?
Diamond's scratch 'hardness' is the highest amongst naturally formed minerals. The only thing that can scratch it, is itself. However it is not 'tough'. Basically, Diamond is brittle. A blow from a solid object may crack it. If a diamond was struck by a bullet, it might shatter.
