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 atoms in pennies share many electrons. Pennies contain bonds. Hydrochloric acid is the main acid that helps break down food in the stomach. The atoms of hydrochloric acid share electrons. Hydrochloric acid contains bonds.

Answer:

If it is a multi select question, it is:

1. Calcium Chlorine (ionic)

2. Copper/Pennies (metallic)

3. Hydrochloric Acid (covalent)

Explanation:

if this isn't the answer im sorry...

In this question, you have to find out the nature of each compound:

A chemical bond may be defined as a type of attraction that is significantly present between atoms, ions, or molecules that authorizes the formation of chemical compounds. In a more simple sense, it may be characterized as a process through which different atoms in a molecule are held together.

Calcium chloride is an ionic compound because the calcium atom transfers electrons to chlorine atoms, leading to the formation of chemical bonds. Whereas the attraction between copper and pennies illustrates a metallic bond because copper atoms in pennies share many electrons.

While the atoms of HCl share electrons in order to break down food in the stomach. So, this reveals an example of a covalent bond.
