Question

identifying types of chemical bonds
calcium chloride is used to make pickles. the calcium atom transfers electrons to chlorine atoms, leading to the formation of chemical bonds. calcium chloride contains bonds.
copper atoms are used to produce pennies. the copper pennies share many electrons. pennies contain bonds.
hydrochloric acid is the main acid that helps break down stomach. the atoms of hydrochloric acid share electrons. hydrochloric acid contains bonds.
(the dropdown options shown in the image are covalent, ionic, metallic)

Explanation:

• Calcium chloride: Electron transfer between metal (Ca) and nonmetal (Cl) indicates ionic bonds.
• Copper pennies: Metal atoms share delocalized electrons, forming metallic bonds.
• Hydrochloric acid (HCl): Electron sharing between nonmetals (H and Cl) indicates covalent bonds.

Answer:

Calcium chloride contains ionic bonds.
Pennies contain metallic bonds.
Hydrochloric acid contains covalent bonds.
