Calcite is the opaque compound calcium carbonate (CaCO3). It will dissolve in carbonic acid and will fizz in stronger acids.
Quartz is the usually transparent compound silicon dioxide (SiO2). It will not dissolve in acid.
You can distinguish quartz from calcite by conducting a hardness test, as quartz is harder than calcite. Additionally, you can test for effervescence with acid - calcite will fizz in acid while quartz will not react. Lastly, observing the cleavage patterns can also help differentiate the two minerals, as quartz has no cleavage while calcite has rhombohedral cleavage.
A scientist can differentiate between calcite and quartz by testing their hardness using the Mohs scale, where quartz has a higher hardness value of 7 compared to calcite's 3. Another method is through a reaction with acid, as calcite fizzes when in contact with dilute hydrochloric acid due to its calcium carbonate composition, while quartz remains unaffected. Lastly, they can use polarized light microscopy to identify the distinctive crystal structures of each mineral.
Calcite reacts more easily with acid compared to quartz. Calcite is a carbonate mineral that effervesces or fizzes when in contact with acid due to the release of carbon dioxide gas. In contrast, quartz is a silicate mineral that is generally chemically inert and does not react with acid.
Calcite crystals will effervesce in vinegar, quartz will not. Quartz will scratch calcite. The opposite is not true. Quartz and calcite have different crystal structures and different specific gravities. The list goes on, but if you are trying to distinguish them, the above should help.
No, calcite is not the chemical name for silicon dioxide. Calcite is a mineral composed of calcium carbonate (CaCO3), while silicon dioxide is the chemical name for silica, which is composed of silicon and oxygen atoms (SiO2).
The major differences between quartz and calcite are hardness and cleavage. Quartz is about twice as hard as calcite. Quartz has little or at least very seldom any sort of obvious cleavage, whereas calcite has excellent and very obvious rhombohedral cleavage.
Calcite is calcium carbonate, and dissolves when in contact with acid.Quartz is silicon dioxide.There are lots of differences between the two... more than they have in common!See the Web Links to the left of this answer for more information.
Quartz is much harder than calcite.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Quartz because its harder than calcite and the quartz in thicker.
apatite will not scratch quartz topaz calcite or corundum

Quartz is harder than calcite, making it more scratch-resistant. Quartz also has a higher melting point than calcite. Additionally, quartz is typically transparent or translucent, whereas calcite can be transparent, translucent, or opaque.

Gold, hematite, calcite, and quartz are all mineral elements.
Quartz would scratch the calcite. Calcite would not scratch the quartz. Calcite will react with dilute hydrochloric acid. Quartz will not. Calcite will exhibit double refraction. Quartz will not. If the crystal forms are intact, quartz crystal may appear six sided with pyramidal terminations. If they are of equal size, the quartz will be heavier.
