Calcium
No, it is not. Calcium is a metal but calcium carbonate is not.
Calcium is a metal
No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.
The reaction between calcium carbonate and sodium metal is likely to produce calcium oxide, sodium carbonate, and carbon as products. Calcium oxide is formed from the decomposition of calcium carbonate, while sodium carbonate is formed from the reaction of sodium metal with carbon dioxide released from the decomposition of calcium carbonate. Carbon is produced as a byproduct.
Calcium oxide
The scientific name for marble is calcium carbonate. Other things that fall under the IUPAC name calcium carbonate are limestone, chalk, aragonite, and calcite.
The Chemical name for limestone is Calcium Carbonate - CaCO3
Magnesium metal is extracted from dolomite, which is a mineral composed of calcium magnesium carbonate. The process typically involves thermal reduction of dolomite to produce magnesium metal and calcium oxide.
The most likely products formed from the reaction between calcium carbonate and sodium metal are calcium oxide (CaO) and sodium carbonate (Na2CO3). Calcium carbonate will react with sodium metal to form calcium oxide, sodium carbonate, and carbon in the form of soot.
The product formed between calcium carbonate and sodium metal is calcium carbide. Sodium metal reacts with calcium carbonate to form calcium carbide, sodium oxide, and carbon dioxide. This reaction is highly exothermic and can result in a violent release of heat.
Calcium Carbonate - also called limestone, calcite, chalk, and marble.
The chemical name for limestone is calcium carbonate.
