Which of the following items is a salt? (1 point)
Tems11 [23]

  • Calcium carbonate is the  salt  among the given options.

  • Calcium carbonate ( CaCO3) can be regarded as  which appears as white and odorless powder or  as a colorless crystals it is  insoluble in water.

  • The chemical  formula is CaCO3. It can be used as an antacid as well as food colouring and a  food firming agent and a fertilizer.

  • Calcium carbonate is calcium salt as well as carbonate salt with one-carbon compound

  • Salt can be regarded as substance which is  produced by reaction between acid and  base. It  consists negative ion (anion) of that acid as well as positive ion (cation) of the base.

  • Sodium hydroxide is a base and not a salt

  • Carbonic acid is an acid and not a salt

  • Therefore, calcium carbonate is the only salt in the among the given options.

Describe the reaction below by listing the
rjkz [21]

Answer:

The covalent bond in Cl₂ is break and combine with sodium to form NaCl through ionic bond.

Explanation:

Chemical equation:

Na  +  Cl₂    →   NaCl

Balanced chemical equation:

2Na  +  Cl₂    →   2NaCl

The given reaction indicate the formation of sodium chloride.

Sodium chloride is an ionic compound. It is formed by the reaction of chlorine and sodium. The type of bond in Cl₂ is covalent. Both chlorine atoms are tightly held together through sharing of electrons. When sodium chloride is formed the covalent between the chlorine atoms are break and it react with sodium . The chlorine toms thus gain the one electron from the sodium atom and became negative ion while sodium by losing its one valance electrons became positive ions. The strong electrostatic forces are develop between them and ionic bond is formed.
