The mineral calcite.
When calcium carbonate is heated, it breaks down by thermal decomposition to carbon dioxide & calcium oxide (quicklime). Here is the word equation: Calcium carbonate --> Calcium oxide + Carbon dioxide Here is the chemical equation: CaCO3 (s) --> CaO (s) + CO2 (g)
Table salt is sodium chloride. Its crystals are cubical.

No, limestone is a carbonate rock formed through chemical precipitation. Sandstone is a classification used for sedimentary rocks ranging in various sizes and compositions. Limestone is CaCO3 where as sandstones are usually quartz (SiO2) and feldspars.
Carbonates contain the carbonate ion CO32-. Acids release hydrogen ions, H+. In the presence of an an acid, the carbonate ion will form carbonic acid, H2CO3, an unstable molecule that readily breaks down into water and carbon dioxide.
calcite
The egg doesn't actually turn into rubber. The vinegar is an acid and the eggshell contains calcium carbonate which is a salt. The acidic vinegar breaks down the calcium carbonate of the shell (the calcium acetate is formed) and therefore dissolves it leaving only the thick membrane surrounding the hard boiled egg. It is only an egg without a shell.
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
When calcium carbonate, or any carbonate is placed in acid, the carbonate ion (CO3^2-) accepts protons from the acid, forming carbonic acid (H2CO3), which is unstable and spontaneous breaks down into carbon dioxide gas (the cause of the bubbles) and water. H2CO3 --> CO2 + H2O
Limestone is calcium carbonate (Ca(CO)3. When sufficiently heated it breaks down into lime (calcium oxide, CaO), and water (H2O).

Halite
This only happens with carbonate minerals. Vinegar contains acetic acid. When an acid reacts with a carbonate there is a substitution reaction that results in the formation of carbonic acid, which rapidly breaks down into water and carbon dioxide. The carbon dioxide, being a gas, will produce bubbles.
Limestone is mainly calcium carbonate, CaCO3. When heated, it breaks down to form calcium oxide and carbon dioxide. Calcium oxide reacts with water to produce calcium hydroxide. Limestone and its products have many uses: for example, in mortar, cement, concrete and glass.
haven't got a clue, i looked this up for my science coursework, but there was nothing! which was really unhelpful :( HELPP! xsame here matey :( idont now poop either ;/ not good isi what we gunna do arghhhhhh im a piarate :L:L:L:L howa you then? wanna be friends? xLimestone is broken down by a thermal decomposition into Quicklime :)Limestone is the same as Calcium Carbonate (CaCO3). When Calcium Carbonate is heated, it breaks down into Calcium Oxide (CaO) and Carbon Dioxide (C02). This is thermal decomposition.Hope this helped. :)
A mineral that breaks into jagged pieces exhibits fracture.
Eggshells contain the calcium carbonate, which is a base. It is the same substance found in limestone. The carbonate (CO32-) ion reacts with acids to form the bicarbonate ion (HCO3-), or carbonic acid (H2CO3), a very weak acid that easily breaks down.
