Limestone is a sedimentary rock that is composed largely of the minerals 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).
All four minerals—quartz, pyroxene, olivine, and calcite—contain silicon as a common element. Quartz and olivine are silicate minerals, meaning they are composed primarily of silicon and oxygen, while pyroxene is also a silicate that includes other metal elements. Calcite, although a carbonate mineral, contains carbon and oxygen in addition to calcium but does not contain silicon. Thus, silicon is specifically common to the silicate minerals among them.

No. Quartz is the most common single mineral.
Limestone is a sedimentary rock that is composed largely of the minerals calcite.
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.
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.

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.
