Answer: Calcium chloride contains ionic bond.
Copper pennies contain metallic bond.
Hydrochloric acid contains covalent bonds.
Explanation:
Covalent bond is a type of chemical bond in which equal sharing of the electrons takes place between both the atoms.When two atoms with slight or zero difference in their electronegatives gets combined they form covalent bond.
Calcium chloride contain ionic bond.
Ionic bond is a type of chemical bond in which completer transfer of electrons take place between both the atoms. When two atoms with large difference in their electronegatives gets combined they form ionic bond.
Hydrochloric acid has covalent bond.
Metallic bond is type of chemical bonding which holds together the metal atoms. The electrostatic force between the conduction electrons and the positively charged metal ions. In this bonding ,sharing of electrons is extended over the entire molecular structure.
Copper pennies contain metallic bond.
