What will scratch serpentine and what does not scratch it?
The Mohs hardness of serpentine is 2,5-3; it a soft mineral. Not scrached by a graphite pen; scratched by fingernail, copper etc.
What are the features that a mineral must have in order to be a mineral?
a mineral needs to have color,luster,hardness,streack to be a mineral
What are chemical properties of minerals?
Common mineral properties include:Breakage- whether the mineral cleaves in predictable patterns or fractures in random patternsColor- some minerals have characteristic colors, while others may come in a variety of colors. Color of minerals is largely due to environmental factors during formation (temperature, radiation, pollution)Hardness- the mineral's ability to resist being scratched, measured by Mohs hardness scale.Luster- how light is reflected off the mineral, is either metallic or nonmetalic. Nonmetallic is broken into 3 subcategories: earthy, glassy, or pearlyCrystal form- the way in which the crystals pattern themselves. There are six major patterns: cubic, hexagonal, tetragonal, monoclinal, triclinal, and orthorhombic.Streak- the color of the powder left behind when a mineral is rubbed over a rough surface (streak plate), reveals the "true" color of the mineralOther Properties:Specific Gravity, magnetism, smell, taste, reaction to acid

What will if you rub a mineral with the hardness of 3 with a mineral with a hardness of 9?
The mineral with hardness 3 will get scratched.
Mineral specimen with a Mohs hardness of 5 can scratch a mineral specimen with a hardness of 3?
Correct, a 5 hardness can scratch a 5 and below.
How can you check if a rock is calcite?
Calcite reacts to acid. The best thing to do to determine if a mineral is calcite is to place a drop of dilute hydrochloric acid on a sample. If the mineral fizzes and carbon dioxide bubbles are produced, the mineral is calcite. Place a drop of dilute hydrochloric acid on the mineral. If it fizzes and carbon dioxide bubbles are produced, the mineral is calcite.
What is the mineral hardness for wulfenite?
2.75 - 3
What mineral has a hardness of 2.5-3?
Calcite is a mineral that is white or colorless and has a hardness of 2.5 and splits with cubic cleavage.
What is the mineral hardness of marble?
Marble isn't a mineral, but it is made out of around 100% calcite, which is typically 2.5 - 3 on Moh's hardness scale.
If a mineral scratches calcite but is scratched by apatite what is the minerals hardness?
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
What hardness does a mineral have if its scratched by glass?
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
Which object can scratch calcite but not apatite?
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Describe what would happen if you rubbed a mineral with a mohs hardness value of 7 against a mineral with a value of 5?
The 5 hardness mineral would like suffer scratches or abrasion.
What the hardness of sulfur?
It's about 1.5-2 on Mohs scale of mineral hardness.
