Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
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.
Sure can. This is why we use " diamond tipped " bits. Diamond is one of the hardest minerals we know of besides Diorite. Both of these minerals are used in construction for " tipping " tools which means the tip of the tool, usually saw blades, are coated in these minerals so they can cut through other softer minerals with relative ease.
Yes, marble does contain quartz. Quartz is one of the minerals that can be present in marble, along with other minerals like calcite and dolomite. The amount of quartz in marble can vary, but it contributes to the overall composition and appearance of the stone.
Quartz because its harder than calcite and the quartz in thicker.
No.because calcite is softer then feldspar
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).

Calcite is commonly found in limestone rocks. It is a major component of limestone, along with other minerals such as aragonite and dolomite. Quartz, on the other hand, is not typically found in significant amounts in limestone.
Many mineral can not scratch Quartz.Remember the mnemonic for Mohs' scale of hardens "The Girls Can Flirt And Other Queer Things Can Do", where the mineral for each first letter is:(softest)TalkGypsumCalciteFluoriteApatiteOrthoclase (Feldspar)QuartsTopazCorundumDiamond(hardest) Thus minerals 1-6 can not scratch quartz.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
