When calcium nitrate is mixed with lithium carbonate, a double displacement reaction occurs, leading to the formation of calcium carbonate and lithium nitrate. This reaction involves the exchange of ions between the two compounds to form the new products.

Chalk is calcium carbonate. Cola is an acid. When these two compounds mixed, hydrogen carbonate is formed. This compound is water soluble, and thus chalk mixed with and acid like cola dissolves in water.
When iodine is mixed with hexane, it typically results in a violet or purple color in the hexane layer. This occurs because iodine is more soluble in non-polar solvents like hexane compared to polar solvents. The distinct color is due to the formation of iodine molecules that are dissolved in the hexane, which reflects the characteristic color of iodine.
Chalk is a mechanical mixture, which means it is a combination of different substances that are physically mixed together but not chemically bonded. It is composed mainly of calcium carbonate and other minerals.
When calcium sulfate (CaSO4) is mixed with iodine, it forms a yellowish-brown color due to the reaction between the calcium sulfate and iodine.
The precipitate formed when sodium carbonate and calcium chloride dihydrate are mixed is white in color. This white precipitate is calcium carbonate, which is insoluble in water.
No, calcium carbonate is not soluble in sodium chloride. When calcium carbonate is mixed with sodium chloride in water, the calcium carbonate will remain as solid particles and not dissolve into the solution.
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
The solubility of calcium carbonate in water is very low; so calcium carbonate form a suspension.
Carbon dioxide gas is produced when calcium carbonate and hydrochloric acid are mixed. This reaction occurs as the acid reacts with the calcium carbonate, releasing carbon dioxide gas as a byproduct.
Limescale is mostly calcium carbonate with some magnesium carbonate mixed in there as well. So the answer would be calcium.
Petrol changes color when mixed with iodine solution due to covalent bonding.
When hydrochloric acid (HCl) is mixed with calcium carbonate (CaCO3), it forms calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O). This is a chemical reaction where the calcium carbonate reacts with the hydrochloric acid to produce these new compounds.
If nitric acid is mixed with calcium carbonate, carbon dioxide gas would be produced along with calcium nitrate and water.
The precipitate produced by the reaction between calcium chloride and potassium carbonate is calcium carbonate. When calcium chloride and potassium carbonate are mixed together, a double displacement reaction occurs, leading to the formation of calcium carbonate, which is insoluble and thus precipitates out of the solution.
Limestone, which contains calcium carbonate, is heated in a kiln to produce lime. This lime is a key ingredient in the production of cement when mixed with other materials such as sand and water.
